How England’s complicated political geography is confusing coronavirus rules

James Cheshire, UCL and Alex Singleton, University of Liverpool As England emerged from its second national lockdown in early December, Boris Johnson, the UK prime minister, faced an onslaught of questions from MPs on both sides of the House of Commons. Each demanded clarity on what the arrangements would be for their particular constituency under…

London’s Population Profile in 1935

The graphic below shows the population of London across a number of transects overlain on the city’s underlying terrain. It was produced by Ordnance Survey in 1935 and is one of the few early examples I’ve seen of the organisation producing “data visualisations” alongside their famous maps (they do a lot more of this now […]

Joy Division, Population Surfaces and Pioneering Electronic Cartography

There has been a resurgence of interest in data visualizations inspired by Joy Division’s Unknown Pleasures album cover. These so-called “Joy Plots” are easier to create thanks to the development of the “ggjoy” R package and also some nice code posted using D3. I produced a global population map (details here) using a similar technique in 2013 and since […]

Population Lines: How and Why I Created It

Thanks to the power of Reddit the “Population Lines” print (buy here) I created back in 2013 has attracted a huge amount of interest in the past week or so (a Europe only version made by Henrik Lindberg made the Reddit front page). There’s been lots of subsequent discussion about it’s inspiration, effectiveness as a form of […]

Mapping the Global Urban Transformation

One of the best datasets for understanding the explosive growth of cities across the world in the last 75 years in the UN World Urbanisation Prospects research, which records individual city populations from 1950 to 2014, and includes predicted populations up to 2030. I have been meaning to create an interactive map of this fascinating data for…

London Population Change 2001 to 2009

In a previous post I talked about the Index of Multiple Deprivation (IMD) in London, and how a “standard” representation only reflects the geographical reality of the land. By utilising a cartogram tool this potential issue can be overcome by rescaling each areal unit by its resident population, for the IMD I used mid-year population estimates available from the Office for National Statistics at Lower Layer Super Output Area (LSOA) level. To add a layer of context to the previous maps, I have constructed cartograms for London to illustrate the change in population between 2001 and 2009. I have used 2001 census data along with 2009 mid-year population estimates to calculate the percentage change for each of the 24,140 output areas (that contain on average 250 individuals nationally) that make up Greater London for the age ranges: 0-4, 5-14, 15-24, 25-44, 45-64 and 65 and over. To create the cartogram aspect of the maps I have used the total population of that particular age range in 2009 to rescale each areal unit. I have also produced the same population change maps using the “standard” representation of London to allow comparison with the cartograms. The results of this can be seen […]

Network Population Density for Southwark

Using the excellent SANET extension for ArcGIS 9.3 I was able to take some of my data for Southwark that I had geocoded to address level, and estimate the population density using the OS Mastermap ITN product. The procedure is essentially a Kernel Density Estimation that takes place on a given network rather than across 2D space, this effectively controls […]

Mapping London’s Population Change 1801-2030

Buried in the London Datastore are the population estimates for each of the London Boroughs between 2001 – 2030. They predict a declining population for most boroughs with the exception of a few to the east. I was surprised by this general decline and also the numbers involved- I expected larger changes from one year to …

Call for papers for themed sessions at the 6th International Conference on Population Geographies

The IGU Commission on Population Geography plans once again to sponsor and actively promote some themed sessions at the bi-annual international population conference to be held in Umeå, Sweden in 2011. The Commission proposes three themed sessions linked to the commission’s core interests in ‘Population and Difference’ and ‘Population and Vulnerability’. A. Population and Difference […]
