No, Brexit is probably not responsible for certain UK cities’ population decline

This year’s Cities Outlook from the Centre for Cities shows that, while the population of the UK continues to grow apace, six cities saw their populations fall. More surprising is that, of the six, four are in the Greater South East of England. So what’s going on?

This group of four is made up of Oxford (a fall of 0.5 per cent), Luton (a 0.6 per cent fall), Aldershot (0.1 per cent fall), and Ipswich (a marginal fall of 0.03 per cent, or 40 people). They’re joined by Aberdeen, which maintains the falls seen in previous years, and Sunderland – where the population growth has been sluggish for some time.

Given the strong growth in the Greater South East’s population as a whole, and the growth seen in previous years in the cities themselves (as the chart below shows), their fall in population is somewhat of a surprise. Digging into the data shows what contributed to this.

An age breakdown of this population data shows that three of the four cities – all except Ipswich – saw a decline in their population aged 25 to 49. Interestingly, this fall was seen in many other cities in the Greater South East, with a total of 15 of the 19 cities in this area losing 25 to 49-year-olds.

The components of population growth – migration to and from the rest of England and Wales, migration to and from the rest of the world, and the difference between births and deaths – show that the main cause of population decline in these cities was people leaving for elsewhere in England and Wales.

Between 2016 and 2017 the four cities lost between 1,000 to over 5,000 people to other British cities. International migration on the other hand, although not necessarily from EU countries, is actually offsetting this loss of population, as the chart below shows.

As we pointed out in our response to the recently released Immigration White Paper, cities are heavily reliant on EU immigration of high-and low-skilled labour, especially in the Greater South East, with the most successful cities, such as Cambridge, Oxford and London, among the places with the highest share of migrants. While many predicted that the 2016 referendum would lead to a decline in this migrant pool, the data available suggests that this is not the reason behind the fall in population in Aldershot, Ipswich, Luton and Oxford to date.

This, of course, is only one year’s worth of data. Only time will tell whether the cities’ population declines, and their demographic make-up, persist in the years to come.

Transport for London’s fare zones secretly go up to 15

Some of these stations are in zones 10 to 12. Ooooh. Image: TfL.

The British capital, as every true-blooded Londoner knows, is divided into six concentric zones, from zone 1 in the centre to zone 6 in the green belt-hugging outer suburbs.

These are officially fare zones, which Transport for London (TfL) uses to determine the cost of your tube or rail journey. Unofficially, though, they’ve sort of become more than that, and like postcodes double as a sort of status symbol, a marker of how London-y a district actually is.

If you’re the sort of Londoner who’s also interested in transport nerdery, or who has spent any time studying the tube map, you’ll probably know that there are three more zones on the fringes of the capital. These, numbered 7 to 9, are used to set and collect fares at non-London stations where the Oyster card still works. But they differ from the first six, in that they aren’t concentric rings, but random patches, reflecting not distance from London but pre-existing and faintly arbitrary fares. Thus it is that at some points (on the Overground to Cheshunt, say) trains leaving zone 6 will visit zone 7. But at others they jump to 8 (on the train to Dartford) or 9 (on TfL rail to Brentwood), or skip them altogether.

Anyway: it turns out that, although they’re keeping it fairly quiet, the zones don’t stop at 9 either. They go all the way up to 15.

So I learned this week from the hero who runs the South East Rail Group Twitter feed, when they (well, let’s be honest: he) tweeted me this:

The choice of numbers is quite odd in its way. Purfleet, a small Thames-side village in Essex, is not only barely a mile from the London border, it’s actually inside the M25. Yet it’s all the way out in the notional zone 10. What gives?

TfL’s Ticketing + Revenue Update is a surprisingly jazzy internal newsletter about, well, you can probably guess. The September/October 2018 edition, published on WhatDoTheyKnow.com following a freedom of information request, contains a helpful explanation of what’s going on. The expansion of the Oyster card system

“has seen [Pay As You Go fare] acceptance extended to Grays, Hertford East, Shenfield, Dartford and Swanley. These expansions have been identified by additional zones mainly for PAYG caping and charging purposes.

“Although these additional zones appear on our staff PAYG map, they are no generally advertised to customers, as there is the risk of potentially confusing users or leading them to think that these ones function in exactly the same way as Zones 1-6.”


Fair enough: maps should make life less, not more, confusing, so labelling Shenfield et al. as “special fares apply” rather than zone whatever makes some sense. But why don’t these outer zone fares work the same way as the proper London ones?

“One of the reasons that the fare structure becomes much more complicated when you travel to stations beyond the Zone 6 boundary is that the various Train Operating Companies (TOCs) are responsible for setting the fares to and from their stations outside London. This means that they do not have to follow the standard TfL zonal fares and can mean that stations that are notionally indicated as being in the same fare zone for capping purposes may actually have very different charges for journeys to/from London."

In other words, these fares have been designed to fit in with pre-existing TOC charges. Greater Anglia would get a bit miffed if TfL unilaterally decided that Shenfield was zone 8, thus costing the TOC a whole pile of revenue. So it gets a higher, largely notional fare zone to reflect fares. It’s a mess. No wonder TfL doesn't tell us about them.

These “ghost zones”, as the South East Rail Group terms them, will actually be extending yet further. Zone 15 is reserved for some of the western-most Elizabeth line stations out to Reading, when that finally joins the system. Although whether the residents of zone 12 will one day follow in the venerable London tradition of looking down on the residents of zones 13-15 remains to be seen.
