Stuart’s 100 #47: The Forgotten Triangle

48: The Forgotten Triangle

Day_48

What if the forgotten triangle behind Shortland Street was more than a parking lot?

Continuing the series on forgotten or underutilised spaces within the city, the steeply rising wedge of land between Shortland Street, Albert Park and Princes Street is certainly a stand out example of well-located land that should be valued and utilised for much more than just parking. Certainly, when one looks at historic photos of this part of the city, it is obvious that this area used to packed quite densely with a much more diverse array of buildings and activities than can be found there now.

It is actually quite crazy that this forgotten corner of the city has not been developed for more intensive and higher value uses, if you think about the location, just one block from both the A-grade office space of the corporate towers on Shortland Street and the high value retail of High Street, and bounded by what is a beautiful historic central city park.

The following is a simple four-point plan that is just a start to indicate how the potential of this part of the city could be reconsidered:

  • Improve the legibility, crossing opportunities and attractiveness of walking links through the area to Albert Park and the universities on the hill;
  • Develop high rise residential towers fronting Kitchener Street similar to the Metropolis tower and Precinct Apartments between Lorne and Kitchener Streets that capitalise on the outlook over the park and up high gain light, air and relative serenity above this quiet part of the city;
  • Rediscover and develop the forgotten laneways of Fields and Bacon Lanes, Chancery Lane, Bankside Street and Cruise Lane as back street extensions to the High Street District with opportunities to open out and activate the backs of Shortland Street towers into a gritty but interesting neighbourhood;
  • Make more use of the Bowen Park extension of Albert Park as a great public open space in its own right, reflecting its north-facing qualities and great views back to this part of the city skyline.

West Auckland Network with new interchanges

Last week Auckland Transport began consultation on the new network for West Auckland. I and many readers were highly critical of it as it seemed to ignore much of the network design philosophy and elements AT are implementing elsewhere and enshrined in the Regional Public Transport Plan. In particular the consultation sees a move away from the idea of a high frequency all day network that may require some to transfer to a network with lots of infrequent routes but may have not direct routes. The two different network design models are shown in the image below.

New Network Model

In most post I speculated the network proposed was a result of not having interchanges at Te Atatu and Lincoln Rd. It appears like that is exactly the case with AT now saying:

AT is redesigning the bus network across all of Auckland. Within each area, there are opportunities to improve public transport. However, the reality is that all changes will take time to implement, especially where major new infrastructure needs to be built, or where the cost of operating services will increase substantially. Both will require more ratepayer (Auckland Council) and taxpayer (New Zealand Transport Agency) funding than is currently budgeted.

For West Auckland, AT has taken the view that it is better to make as many improvements as we can afford to make in the next 2 years, to take advantage of the benefits electric trains will bring, rather than wait until all of the desirable infrastructure is in place.

The current proposal which is out for consultation is shown on the left-hand diagram below. On the right-hand diagram is the network we want to implement as soon as we have the necessary funding and consents to build interchanges at Te Atatu and Lincoln Rd, in anticipation of the long-term proposal to build a Northwestern Busway. We hope this clearly illustrates the benefits of the more frequent and better connected network that will be possible once the required infrastructure is funded and built.

West Auckland With and Without Interchanges

To me the network on the right is so much cleaner and easier to understand as well as being more useful due to the higher frequencies. What’s clear is both AT and the NZTA need to urgently get on with sorting out the interchanges at Lincoln Rd and Te Atatu to enable the new network to properly implemented. I suggest that anyone submitting on the West Auckland Network highlight the need for the right hand image to become a reality.

Climate change and New Zealand cities

Environmentalists sometimes have an uneasy relationship with cities. Because they concentrate a lot of people and economic activity in relatively small places, they also concentrate a lot of negative environmental effects. All that concrete, all that energy being consumed, the kilometres of malls and highways and subdivisions! It can’t possibly be good, can it?

As it turns out, cities can be quite environmentally friendly. The same factors that make cities economically efficient – the ease of interacting with others in a dense environment and the economies of scale that arise in large, well-connected places – can also make them environmentally efficient.

However, there are large variations in environmental efficiency within and between cities. Cities which offer better housing and transport choices tend to have much lower per-capita carbon emissions – a fact highlighted by a 2011 study of carbon emissions in 100 cities:

  • In the United States, the emissions per person in Denver are double those of people in New York, which has a greater population density and much lower reliance on private vehicles for commuting.
  • In Toronto, residential emissions per person in a dense, inner city neighbourhood with a high quality public transport system are just 1.3 tonnes of carbon dioxide equivalent, compared to 13 tonnes in a sprawling distant suburb.

Auckland’s Low Carbon Action Plan presents some of this data in a fascinating infographic:

Per-capita emissions in cities

Interestingly, Auckland doesn’t come out too bad on this comparison. We’re nowhere near as efficient as Vancouver, Stockholm, or Copenhagen, but we are in the same ballpark as moderately efficient North American cities like New York and Seattle. This is probably down to our high share of renewably generated electricity, as well as our relatively short commutes.

But can Auckland become more environmentally efficient, or will it grow in a way that causes it to lose its edge? In order to get a sense of this, I took a look at variations in carbon emissions from commutes within New Zealand’s three largest cities.

The maps below presents some preliminary estimates of carbon emissions. They’ve been calculated using the Census journey to work data presented in my recent Location Affordability Index paper, which allowed me to identify how far people were travelling to work and what mode of travel they were using, as well as some supplementary assumptions and estimates from several sources (e.g. EECA, NZTA). [I will put together a working paper on the analysis when my work at MRCagney permits!] Lighter yellows reflect lower average annual carbon emissions from commute trips, while darker blues represent higher emissions.

Annual CO2 emissions per commuter DRAFT v1

A few first thoughts about these findings:

  • These maps really show the power of proximity. People near the centre of the city tend to travel shorter distances to work, on average, because they’re closer to more jobs. This is obviously good for commuters – which is why house prices are so high in Ponsonby and Mount Eden – but it’s also great for the environment.
  • They also demonstrate the importance of transport choices. Commute emissions in Wellington suburbs tend to be much lower than in similarly-situated Auckland suburbs, because many Wellingtonians can choose between driving, an efficient electric train system, a frequent bus network, and relatively good walking and cycling.
  • Lastly, these maps highlight the perils of urban growth. Suburbs at the fringe of the city are much less environmental efficient than suburbs closer in. For example, moving from Mount Eden to Flat Bush could be expected to raise your commute emissions by one ton a year. (And leave you sitting in traffic for that much longer!) This is a particular challenge right now in Christchurch, where satellite towns with long commutes have absorbed households displaced by the earthquakes.

Of course, as a coastal city Auckland has some strong incentives to reduce its carbon emissions:

Auckland Transport’s 30 Year Project List

As part of the discussion on Alternative Transport Funding, which was launched yesterday, the Council also released a copy of Auckland Transport’s entire 30 year transport programme which includes the cost of projects and seemingly ranked according to some combination of criteria. The programme unfortunately does not include state highway projects, which makes it difficult to fully assess the merits of the overall transport packages outlined in yesterday’s announcements. However, it’s certainly clear what Auckland Transport projects can and cannot be afforded over the next 30 years under the two scenarios.

The document doesn’t explain the list in any detail, but it seems as though there are a number of projects on the first page which have some form of existing commitment or are ongoing requirements and therefore are not really considered “discretionary”. These are shown below:

committed-projectsThe ‘committed’ projects include those that appear to have contracts in place (electric trains, Albany Highway, a few things around Westgate), renewing existing assets and the City Rail Link. I actually wonder if it would be helpful for CRL to be ranked against all the other projects – rather than be included in this “other” list – as almost certainly it would rank either right at the top or very near it.

Anyway, moving on to the top of the list the projects listed below are those that are in both the Basic Network and the Auckland Plan Network – as well as some fairly broad brush allocation of funding to support sprawl in some of the areas identified by the Unitary Plan:

basic-network-projects

It’s a pretty short list for the 30 year transport programme, as well as being strangely focused on the first decade. The other key thing to notice here is the yellow boxes, which appear to be wrapped up programmes of projects (e.g. walking and cycling) where the amount of funding allocated to the programme varies quite significantly, depending on whether it’s the Auckland Plan Transport Network or the Basic Transport Network.

Even taking a fairly harsh look at the list above, there doesn’t seem to be too many projects that don’t make sense doing at all over the next 30 years. For me the three most glaring ones that need to be questioned are:

  • The Reeves Rd flyover at $141 million
  • The widening of the almost $200 million and soon to be opened Te Horeta Rd for another $74 million
  • Mill Road at $472 million which is something that we’ve highlighted could be looked at for a cheaper option, especially seeing as the government are now widening the southern motorway.

The rest of the projects are those which form part of the Auckland Plan Transport Network only. Essentially, these are the additional projects from Auckland Transport which the additional funding is being asked to pay for:

auckland-plan-network-projects

While there are a few really dumb projects on the list above (Mt Albert Park & Ride, what the heck?) there’s also a lot of pretty good stuff that is missing out under the Basic Transport Network. Furthermore, while there is some, it seems at first glance that there isn’t a huge amount of really expensive dumb stuff in the programme list of Auckland Transport’s projects. That contrasts with the package of state highway projects highlighted yesterday which doesn’t appear to have been questioned at all.

Over the next few days I’ll be starting to look into the detail at the overall balance of the packages, as well as assessing the extent to which they are similar to what we proposed in the Congestion Free Network.

Alternative Transport Funding Report Released

The latest report on alternative transport funding for Auckland, prepared by the Independent Advisory Board (formerly the Consensus Building Group), has just been released. The report will form a critical part of the Council’s public consultation on the next Long Term Plan (the 10 year budget), essentially asking Aucklanders two key questions:

  • Are you willing to pay more for a better transport network?
  • If so, then should that extra money be from existing sources (rates, fuel taxes etc.) or from a “motorway user charge”?

We have been highly skeptical of past proposals that request more money to be spent on transport – in particular the first version of the Integrated Transport Programme as well as the initial report on alternative funding prepared last year by the Consensus Building Group. In fact, the Congestion Free Network came into being as a result of our frustration with the transport programme being a “build everything” and we felt a large part, if not all of the $12 billion funding gap could be resolved through removing poor value projects, rather than by requiring additional funding.

Overall, the new report is a clear step in the right direction and combined with the work being done as part of the next LTP and the next ITP it seems as though quite a lot of effort has gone into removing the more idiotic projects included in the original ITP, although there isn’t a huge amount of detail in the information that has been provided. There are, however, still many unanswered questions that the report doesn’t seem to address – plus its key recommendation of suggesting a “motorway user charge” is fraught with problems. But I’ll get onto that in a moment – first to summarise some key points from the report.

A comparison between what is in the two programmes – known as the “Basic Transport Network” (that which can be afforded under the 2.5-3.5% rates increase proposed in the LTP) and the “Auckland Plan Transport Network” (the preferred network, which requires additional funding) is shown in the series of tables below.

Firstly, for bus and ferry investment:

bus-ferry

The main difference between the two networks seems to be in the scale of the bus lane programmes and the provision of additional busways in the second and third decades, supported by service frequency improvements. The proposed Botany to Manukau busway appears to be extended to the airport like we suggested as part of the CFN however more interesting is to see a new proposal for a “cross isthmus” bus RTN between New Lynn, Onehunga and Otahuhu. I wonder what route and form that would take.

Next for rail:

railThe difference between the two networks is fairly stark in the second and third decades, with no investment at all in rail over this period in the Basic Transport Network. I must say the complete lack of rail investment in the Basic Transport Network after 2025 is a bit surprising and raises some questions about the prioritisation process that determines what’s in and what’s out of the Basic Transport Network after 2025. Importantly, CRL is in the Basic Transport Network and therefore does not require alternative funding.

Next, for roads:

roadsLooking at arterial roading projects first, it’s clear that even the Auckland Plan Transport Network is much smaller than what was proposed originally in the first version of the Integrated Transport Programme. In fact it seems like billions upon billions have been shaved off the previous ITP’s numbers, which included crazy things like nearly a billion dollars on upgrading Great South Road. We’ll take a more detailed look at this in a future post, but credit where it’s due to Auckland Transport who have responded to criticisms of the first ITP by ensuring the Auckland Plan Network has been significantly refined to deliver much better value for money.

Unfortunately the same cannot be said about the state highway programme, which doesn’t vary much between the two networks – aside from some rather optimistic “widening to reduce congestion” in the final decade (haven’t they heard of induced demand?) A whole bunch of very dodgy projects (Additional Harbour Crossing, SH16 Port Access, SH1 Warkworth to Wellsford etc.) have been included in the Basic Transport Network for some unknown reason, as well as of course being in the Auckland Plan Transport Network. This is important to keep in mind when considering the resulting “funding gap” – which of course could be a whole heap smaller if we stripped out the $5.5 billion Harbour Crossing and multiple billions on these other unnecessary projects.

Components of the walking, cycling and safety programmes for the two networks are shown in the table below:walking-cyclingIt’s not clear what the cost difference for walking and cycling is between the two networks, but it’s clear that only the Auckland Plan Transport Network goes anywhere close to delivering on the Auckland Plan vision for active transport.

Now for miscellaneous other stuff, like maintenance, renewals and supporting sprawl:

maintenance-renewalsThe shortfall in funding maintenance and renewals under the Basic Transport Network is a real concern, as the last thing we want to do is end up like the USA where infrastructure is falling to bits because politicians want to “cut ribbons” rather than look after what we already have. The lack of funding for developing the greenfield sprawl areas may not be such an issue as this could force the developers themselves to come to the party a bit more.

Overall, as I noted above it’s clear the Auckland Plan Transport Network is vastly improved from what was in the first ITP. A lot of the really poor investment in the arterial network appears to have disappeared, although there are still a few remaining remnants like Penlink and Mill Road, although even with these projects it seems like the bulk of spend has been pushed out into the future. However, the big remaining issue is that a similar exercise doesn’t seem to have occurred with the State Highway network and there are still billions upon billions of dollars in poor value for money projects – most particularly the Additional Harbour Crossing but also other duplicative projects like SH20B, Warkworth-Wellsford and others. NZTA have really dropped the ball on this one and unfortunately I suspect part of this comes about because the under the current situation motorway projects get full government funding while every other transport project has to beg for a slice of the funding pie. More than once I’ve heard council people say we should build certain projects simply because the government are paying for them.

Cut out what I estimate to be around $8 billion in very poor value for money state highway projects and we’re left with a $4 billion funding gap. If we push $8 billion of state highway projects out of both the Basic Transport Network and the Auckland Plan Network, it means we can afford $8 billion more of good projects before we have to turn to Alternative Funding and it means that we only need to find ways of raising an additional $4 billion. Over 30 years, that’s not a particularly huge issue to overcome.

So if we think back to the two questions at the top of the post, it seems as though the answer to the first one is there may well be value from paying a bit more to get a better transport network, but the actual requirement for additional funding might be around a third of what the report highlights. Now let’s turn to the second question of which would be the best way of raising this additional funding.

Essentially the two options proposed are:

  1. Increasing existing funding mechanisms like rates, fuel taxes, development contributions, central government grants etc.
  2. Introducing a charge for entering the motorway network

Some more detail on the “Rates and Fuel Tax” option are shown below:

rates-fuel-taxI must say I was pretty surprised to see how low the additional rates and fuel tax increases would need to be in order to close the funding gap. A rates increase of between 3.4 and 4.4% is actually lower than what was assumed in the 2012 Long Term Plan (that had 4.9%) while a 1.2 cent per litre annual fuel tax hike would probably get lost as a rounding error in typical price fluctuations. It’s a credit to Auckland Transport’s project prioritisation that they’ve managed to develop a network that could be fully funded under the funding assumptions of the 2012 Long Term Plan, and it’s only the political decision to have a much lower rates increase that’s essentially “re-created” the funding gap.

Combine this with the above observation that the “funding gap” could be further reduced to around $4 billion instead of $12 billion and we could see the gap closed by rates increases only 0.3% higher than otherwise or fuel tax increases of a mere 0.4 centre per litre compared to what would otherwise occur. That’s starting to look like a pretty compelling option.

The other funding option is called a “Motorway User Charge” and is summarised below:

motorway-user-chargeThere’s a lot of discussion in the document around the relative costs and benefits of the two approaches – with the report seeming to express something of a preference for the motorway user charge scheme, based on its travel demand management effects of discouraging some trips and encouraging higher levels of public transport use. We’ll look at the details of this analysis in further posts, but note that this option does come with some fairly significant set up and operational costs (~$110 million set up with opex costs of 24c per trip) as well as potentially diverting quite a lot of traffic off the motorway network and onto local roads – which seems quite counter-productive.

To summarise, there’s quite a lot to like in the Independent Advisory Board’s report. It seems like some hard work has gone on by Auckland Transport (although sadly not NZTA) to optimise their desired transport network so it’s far more realistic than what was proposed in the first ITP. Take out a few of the dumber motorway projects and we’re left with a pretty damn good 30 year transport network that can almost be funded from existing sources (just requiring 0.3% higher rates increases and 0.4 cents per litre higher fuel tax increases) or from a very low motorway user charge. Or from other ways we might think up of to find $4 billion over 30 years.

 

Update: unsurprisingly the government has once again poured cold water on the idea of tolling or fuel taxes.

The good news about intensification

I thought a commenter on a recent post about a new apartment development on Great North Road had a really great point about the state of the debate:

…the fact is the intensifiers are not winning the argument, as was noted by someone else above. I wish they were but with the tin-ear people have here for this sort of argument, it doesn’t surprise me that it is being lost. Compare the nuanced arguments made here about transport (expansive, studied proposals like the CFN) to the “developers and freemarkets will sort it out” type arguments around intensification and you’ll see what I mean.

This rings true to me. Although I would argue that a lot of thought has gone into Transportblog’s analysis of policies like the Unitary Plan or the effects of limits on density, it’s often difficult to tell the good news stories about market-led intensification.

This is challenging in part because there appear to be trade-offs. Building an apartment building in Ponsonby is obviously a good thing for new residents, as they get to live in a nice area that they might not otherwise be able to afford. But it also has some disadvantages for existing residents, who may feel like they have to put up with more traffic, less sunlight on their porches, and so on and so forth.

In short, it’s easy to fall into an “us versus them” narrative – which is what I was arguing against in the earlier post. I don’t think this is necessary. There are many positive stories about rising residential densities and a lot of benefits for existing residents. We should start telling these stories.

Basically, it boils down to this:

If more people live in a neighbourhood, more services will be available locally for all residents.

Higher population densities make it more efficient for transport agencies to run high-frequency bus routes. They make it easier for supermarkets to open up in closer proximity, competing down prices for groceries. They make it easier for councils to justify improving local parks, improving streetlighting, and upgrading streets. Density allows there to be a cafe or two on every block, so residents can easily step out for a hot drink in the morning. This is all good stuff!

Essentially, having more people around you means that there’s a bigger local market for all sorts of useful things. As densities increase, neighbourhoods will become more convenient for the people who live in them. But if they don’t, there’s never going to be a reason to run a bus every ten minutes. There’s never going to be an incentive for Countdown to open a shop one kilometre down the road from New World. The cafes and drycleaners and florists will never set up across the street.

Here are a few examples of the kinds of environments that could be enabled by intensification. Importantly, these aren’t high-density neighbourhoods – they tend to be composed of terraced houses, row houses, and 4-6 storey apartment buildings rather than massive high-rise towers.

Here’s Greenwich Village, Jane Jacob’s old hood and one of Manhattan’s medium-density neighbourhoods. Look at how many retail and dining choices the residents have:

manhattan greenwich village

Here’s a typical cafe in Paris, another city that’s great due to its density and mix of uses. The city’s awash in local cafe and restaurant options because it is dense enough to support lots of them.

paris_cafe-rainbow_tours

Here’s an example from San Francisco – the Castro district, which is one of the spiritual homes of gay and lesbian culture in North America. Medium densities in the area support fantastic (if a bit off-the-wall) nightlife.

san francisco the castro

And finally, one from Auckland: this is the Elliot Street shared space, which never would have happened without the apartment boom in the city centre. I bet a lot of people around Auckland are looking at how great this is and asking, “when will my neighbourhood get something like this?” The answer is: When your neighbourhood has enough people to support it!

ELLIOTT ST

So, what would you like to see happening in your area? Do you think that having a few more people around would help it happen?

Introducing: Vancouver Cycle Chic

Vancouver Cycle Chic documents the emerging bike culture in Vancouver. In addition to the rich imagery of their website there is also a series of amazing videos produced by Chris Bruntlett. Spoiler: the videos aren’t about bikes, transport, or other narrow subjects but about people, their stories, and how the city meets their lifestyles and aspirations.

This is my favourite.

Chris and Melissa Bruntlett will be in New Zealand this week. They are speaking at 2 Walk Cycle conference in Nelson and an Auckland Conversation next Tuesday. (RSVP to this event soon as it is filling up.)

There is also a bike ride  organised by Generation Zero, Frocks on Bikes and TransportBlog this Sunday – Blend with the Bruntletts. More details, including the route will be published shortly.

Auckland Transport Late October Board Meeting

The Auckland Transport board meet today and other than the outstanding patronage results, here are the other items on the on the agenda or in the public reports of note. Firstly the closed session which once again contains quite a few interesting topics including:

  • Newmarket Crossing – This is the Sarawia St level crossing issue.
  • Penlink Designation – AT have been looking to make changes to the existing designation to Penlink although hopefully this doesn’t mean it is moving any closer to actually being built.
  • CCFAS2 – AT are being very secretive about just what the second CCFAS is looking at.
  • Integrated Fares Business Case
  • Amendments to Statement of Intent 2014-17 – perhaps they’re correcting for the really low rail patronage targets.
  • Parking Consultation Analysis – the feedback from the draft parking strategy consultation a few months ago.
  • CBD/West Transport – I’m not sure what this is about but I was told it is confidential as involves property acquisitions (or the potential for them).

On to the items that are in the public session. From the board report:

AT are responsible for developing a region wide wayfinding system. Some of it has started to appear and they say the next stage will see precinct specific signage go through user testing and stakeholder feedback in January and February next year.

Construction of the Wolverton to Maioro cycle route will happen over the year end school holidays

AT say after reviewing feedback to the consultation on cycling routes through Wynyard they are now looking at alternative options. You may recall these are the cycling routes that many of the local marine businesses complained about claiming the loss of parking would destroy their businesses despite them having off street parking and the on-street parks being empty a large amount of the time.

AT are still working on the new Otahuhu Bus-Train interchange however they seem to be getting more vague about when it will be completed. This is important as the roll out of new network for South Auckland is reliant on the completion of this interchange and when announced at the end of last year was planned for mid-2015. In August they said the bus portion was targeted for completion in July 2015 with the rail upgrade completed by the December 2015. In September they said the target for completion was by the end September 2015 although this wasn’t specific to modes like August was. Now they are saying the interchange is scheduled for completion in the last quarter of 2015 and aligned to the new network. This suggests a delay both for the interchange and for the bus network rollout.

There are now 29 of a total 57 EMU’s now in Auckland with 24 unit’s with provisional acceptance (up from 20 in the September report). They say two more are due to arrive in November and another seven in December. Regular train users will have seen the EMUs start to be stabled at the old Auckland Railway station as Wiri only has the capacity to store 28 trains.

There is more detail about the upcoming timetable change which will be the first major one for a number of years. It will come in on the 8th December and as we found out last month all services from Pukekohe or Papakura will go via Newmarket and all services from Manukau will be via Glen Innes. The services on the Manukau line will increase to 10 minute frequencies and should also hopefully include some longer trains. Now AT are also stating that weekend trains to Onehunga will also see improvement moving to a 30 minute frequency (it would be good if they did 30 minute frequencies on weekdays too). Early testing of electric trains on the Western line has also commenced after Kiwirail finally finished in September, over a year late.

The first stage of AMETI is now effectively complete. The new road parallel to the rail line and which includes a 220m tunnel next to the station, named Te Horeta Rd, opens to traffic this Sunday 2nd November and there’s a public open day on Saturday 1st from 11am to 3pm. A separate paper to the board shows some before and after photos. AT say there is still expected to be some minor works on the project till early next year and that the final cost for this stage is expected to be $212 million compared to the project budget of $239 million. Here is a video from AT of the road.

HOP use as a percentage of all trips remained at 71% after jumping strongly in July and August following the change in fares from early July despite AT selling 15,000 new ones in September. AT say that now almost 420,000 have been sold with around 56% of them registered. The exact figures aren’t clear but it appears that HOP use for rail and bus is approximately 79% and 69% respectively. We’re now almost two years since HOP first started rolling out so this got me thinking about how the uptake of HOP compares to similar situations overseas. Back in May 2013 AT received this report from Deloitte doing just that. In the absence of the actual data behind the graphs, I’ve manually added approximately where HOP is and as you can see the result looks pretty good. I would suggest to AT staff that they might want to highlight this fact.

HOP usage compared to other cities estimation

In a good move AT now have an agreement in place with Budgetary Agencies which allows them to give out a free HOP card as part of the assistance they give to clients.

Why Demographia’s data is irrelevant and misleading

Demographia is a pro-sprawl think tank in the USA that publishes density and house price data for cities across the world. They’re often seen using their statistics to argue that the only way to deliver affordable housing is with suburban fringe expansion into greenfields land.

Demographia’s data on housing affordability has come under fire in the past for slipperiness with definitions and misleading choice of measures. But their analysis of population density has gotten less attention – although it’s even more riddled with errors.

Demographia’s approach to calculating density is simple but misleading. They have simply calculated the total number of people in each city and divided it by the total land area covered by that city – including unpopulated areas like parks and reserves. This measure of average density is actually quite irrelevant. For example, Demographia uses it to claim that Los Angeles is more dense than New York.

As Peter outlined in this recent post, what is much more relevant is the density of the neighbourhood that the average person lives in, rather than the density of the average acre of land in the city.

For argument’s sake, consider a village of one hundred acres with one hundred residents. By the measure of area weighted density the density is simple, one person per acre. Does this represent the reality of how people live? Well it could, if everyone lived alone in a separate house on an acre of land. But what if they didn’t? What if everyone lived in a single apartment block in the middle of town that sat on one acre of land? Well then the density the people actually live at would be 100 people per acre. That’s a hundred times more dense… but the same density by Demographia’s measure!

And what if it were something more complex? What if a quarter of the town lived in the one apartment building, half lived in eighth-acre sections around it, and the remaining quarter were spread out over the rest of the land? Doesn’t that sound a bit closer to the reality of most cities? One person per acre means nothing for this theoretical town, half the people live at eight times that density and a quarter at fifty times the density.

Just in case you’re still unsure, in the image below the dots represent dwellings and each box has the same number of dots in it. Overall they have the same average density however in reality they would feel like two very different places.

In short population-weighted density is a much better indicator of the density of the neighbourhoods people chose to live in, and a much better way to describe cities and housing.

With that in mind, it was a simple task to take Peter’s data and throw it on a chart. In simple terms these show how many people live in neighbourhoods (Census meshblocks to be precise) grouped by density in Auckland, Wellington and Christchurch.  I’ve also picked out the density level that Demographia says each city is.

It’s easy to see a few things here. First of all we can see that neighbourhood density can vary quite a lot within cities. One number just can’t describe how people live. Second, we can see there is something of a bell curve. Most people live within the middle range of densities, those living very low or very high are small in number, but that middle is actually quite broad. Third, we can see how far off Demographia is. Their supposed summary statistic isn’t anywhere near the middle of the curve, it’s actually near the bottom in each case.

For example it seems the Demographia figure describes the density at which roughly five percent of Aucklanders live. Nine percent live at lower densities, and 86% live at higher densities. Many people live in neighbourhoods that are two or three times more dense than Demographia’s misleading average. In short, Demographia’s figures are irrelevant for the vast majority of Aucklanders (and Wellingtonians, and Christchurchers). They don’t reflect how the majority of people choose to live.

Sorry Demographia, your data is plain useless.
