Here are three apps which are involving everyone in city-planning

Cities work best when everyone works together – but putting this into practice can be tricky.

Could apps have the answer? Here are three examples for any budding city-planners out there.

Prospecting for sunlight

If you like Pokémon Go and saving the planet, then you’ll love the new “Look Up” app from the carbon-cutting charity 10:10.

Launched in September 2016, this nation-wide app asks users to spot rooftops with a potential to host solar panels. There are even prizes for those who log the largest solar potential before 30 October.

“Taking action on climate change doesn’t have to be a matter of graphs, grids, floods and dying polar bears,” said Alice Bell, the head of communications at 10:10. “It can be a playful, adventurous re-imagining of how we design our futures.”

By documenting your chosen roof’s orientation and the shade around it, walkers can tackle the issue of untapped solar capacity. 10:10 will then create a national Look Up database from users’ data – with the potential to be a kind treasure-map for app users and for city planners alike.

Permanent route planning

The Strava app gives cyclists and pedestrians an opportunity to help design new bike lanes. By tracking your runs and rides via GPS, the website allows you to compare your journey times and distances to other users. 

It also records your data, and transportation planners can then access Strava Metro for a deep analysis of cyclist and pedestrian activity. This helps them assess the effectiveness of the traffic control already in place, and work out where best to place new lanes.

Vast amounts of money and time are wasted by the current methods used to count cyclists. Videotaping traffic while someone sits beside the monitor has proven to be awfully time consuming, while battery-operated bike counters only provide data for one location. 

But, claims co-founder Michael Horvath, “Strava Metro has the potential to provide the answers”.

Collaborative infrastructure

Planning urban infrastructure used to be a top-down process. Information flowed almost entirely in one-direction: planners produced a package of work, then handed it off to the architects, and never spoke to them again. Architects did the same, handing their work onto the engineers, and so on down the line.

Podaris’s cloud-based platform was developed to change that: to ensure that everyone directly or indirectly involved in producing a project is on the same page and up-to-date.

The firm’s founder Nathan Koren argues that projects that involve people with “diverse interests making changes to it on a daily basis” need effective collaboration in order to work together in a cohesive fashion. His app, he claims, does just that: enabling real-time collaboration with anyone in the world, and shortening feedback cycles “from months to milliseconds”.

Was the decline in Liverpool’s historic population really that unusual?

It is often reported that Liverpool’s population halved after the 1930s. But is this true? Or is it a myth?

Often, it’s simply assumed that it’s true. The end. Indeed, proud Londoner Lord Adonis – a leading proponent of the Liverpool-bypassing High Speed 2 railway, current chair of the National Infrastructure Commission, and generally a very influential person – stood on the stairs in Liverpool Town Hall in 2011 and said:

“The population of Liverpool has nearly halved in the last 50 years.”

This raises two questions. Firstly, did the population of the City of Liverpool really nearly halve in the 50 year period to 2011? That’s easy to check using this University of Portsmouth website – so I did just that (even though I knew he was wrong anyway). In 2011, the population of the City of Liverpool was 466,415. Fifty years earlier, in 1961, it was 737,637, which equates to a 37 per cent drop. Oops!

In fact, the City of Liverpool’s peak population was recorded in the 1931 Census as 846,302. Its lowest subsequent figure was recorded in the 2001 Census as 439,428 – which represents a 48 per cent decline from the peak population, over a 70 year period.

Compare this to the population figures for the similarly sized City of Manchester. Its peak population also recorded in the 1931 Census as 748,729, and its lowest subsequent figure was also recorded in the 2001 Census, as 392,830. This also represents a 48 per cent decline from the peak population, over the same 70 year period.

So, as can be seen here, Liverpool is not a special case at all. Which makes me wonder why it is often singled out or portrayed as exceptional in this regard, in the media and, indeed, by some badly briefed politicians. Even London has a similar story to tell, and it is told rather well in this recent article by a Londoner, for the Museum of London. (Editor’s note: It’s one of mine.)

This leads me onto the second question: where have all those people gone: London? The Moon? Mars?

Well, it turns out that the answer is bit boring and obvious actually: after World War 2, lots of people moved to the suburbs. You know: cars, commuter trains, slum clearance, the Blitz, all that stuff. In other words, Liverpool is just like many other places: after the war, this country experienced a depopulation bonanza.


So what form did this movement to the suburbs take, as far as Liverpool was concerned? Well, people moved and were moved to the suburbs of Greater Liverpool, in what are now the outer boroughs of the city region: Halton, Knowsley, St Helens, Sefton, Wirral. Others moved further, to Cheshire West & Chester, West Lancashire, Warrington, even nearby North Wales, as previously discussed here.

In common with many cities, indeed, Liverpool City Council actually built and owned large several ‘New Town’ council estates, to which they moved tens of thousands of people to from Liverpool’s inner districts: Winsford in Cheshire West (where comedian John Bishop grew up), Runcorn in Halton (where comedian John Bishop also grew up), Skelmersdale in West Lancashire, Kirkby in Knowsley. There is nothing unique or sinister here about Liverpool (apart from comedian John Bishop). This was common practice across the country – Indeed, it was central government policy – and resulted in about 160,000 people being ‘removed’ from the Liverpool local authority area.

Many other people also moved to the nearby suburbs of Greater Liverpool to private housing – another trend reflected across the country. It’s worth acknowledging, however, that cities across the world are subject to a level of ‘churn’ in population, whereby many people move out and many people move in, over time, too.

So how did those prominent images of derelict streets in the inner-city part of the City of Liverpool local authority area come about? For that, you have to blame the last Labour government’s over-zealous ‘Housing Market Renewal Initiative’ (HMRI) disaster – and the over enthusiastic participation of the then-Lib Dem controlled city council. On the promise of ‘free’ money from central government, the latter removed hundreds of people from their homes with a view to demolishing the Victorian terraces, and building new replacements. Many of these houses, in truth, were already fully modernised, owner-occupied houses within viable and longstanding communities, as can be seen here in Voelas Street, one of the famous Welsh Streets of Liverpool:

Nonetheless: the council bought the houses and ‘tinned them up’ ready for demolition. Then the coalition Conservative/Lib Dem government, elected in 2010, pulled the plug on the scheme. 

Fast forward to 2017 and many of the condemned houses have been renovated, in a process which is still ongoing. These are over-subscribed when they come to market, suggesting that the idea was never appropriate for Liverpool on that scale. 

At any rate, it turns out that the Liverpool metropolitan population is pretty much the same as it was at its peak in 1931 (depending where the local borough boundaries are arbitrarily drawn). It just begs the question: why are well educated and supposedly clever people misrepresenting the Liverpool metropolis, in particular, in this way so often? Surely they aren’t stupid are they?


And why are some people so determined to always isolate the City of Liverpool from its hinterland, while London is always described in terms of its whole urban area? It just confuses and undermines what would otherwise often be worthwhile comparisons and discussions. Or, to put it another way: “never, ever, compare apples with larger urban zones”.

In a recent Channel 4 documentary, for example, the well-known and respected journalist Michael Burke directly compared the forecast population growths, by 2039, of the City of Liverpool single local authority area against that of the combined 33 local authority areas of Greater London: 42,722 versus 2.187,708. I mean, what bizarre point is such an inappropriate comparison even trying to make? It is like comparing the projected growth of a normal sized-person’s head with the projected growth of the whole of an obese person, over a protracted period.

Having said all that, there is an important sensible conversation to be had as to why the populations of the Greater Liverpool metropolis and others haven’t grown as fast as maybe should have been the case, whilst, in recent times, the Greater London population has been burgeoning. But constantly pitching it as some sort of rare local apocalypse helps no one.
