Housing has always been a decisive and sometimes divisive political issue. Home ownership has of course long been an aspiration for many people, and in the post-war period between 1953 and 1971 the number of households renting and owning reached an equal level, as documented in official census statistics for England and Wales. Ownership then surpassed renting, reaching its peak in 2001 at 69%. In the decade that followed, this number went down to 64%. The following two maps show the ownership rate in the UK in a conventional and an equal population projection:
The outcome of the referendum over the United Kingdom’s membership of the European Union raises some crucial questions over the country’s economic relationship with the remaining 27 member states. Economic issues over trade were among the most heavily debated issues throughout the campaign. Now that the decision has been made, existing ties with the EU need to be carefully considered in any future trade relationship with the European Union. In a contribution for the “In Focus” section of Political Insight (December 2016, Volume 7, Issue 3) I mapped out Britain’s complex trading relations with the rest of the European Union and created a series of cartograms from the underlying statistics:
Nuclear power contributes only a small share to the global energy production. According to the World Energy Statistics 2015 published by the International Energy Agency (IEA) nuclear power accounts for 4.8% of the total primary energy supply worldwide, far behind oil (31.1%), coal (28.9%), natural gas (21.4%) and even behind biofuels and waste (10.2%).
Of the producers of nuclear power, the United States are by far the largest with 33.2% of the world’s total, followed by France (17.1%) and Russia (7.0%). The United Kingdom’s production accounts for 2.9%. In contrast, France generates the largest share of its domestic electricity generation from nuclear power (74.4%). It is followed by Sweden (43.4%), Ukraine (43.0%) and South Korea (25.8%), while the United Kingdom comes fifth with 19.2%.
As part of the new Sustainable Development Goal 3 which aims to “ensure healthy lives and promote well-being for all at all ages” the UN concludes, that “the incidence of [HIV] has declined globally since 2000. […] The incidence of HIV was highest in sub-Saharan Africa, with 1.5 new cases per 1,000 uninfected people.” Despite longer term positive trends, a recent UNAIDS report stated that “new HIV infections among adults have stalled, failing to decline for at least five years.” This shows that HIV remains a global challenge that needs continuing prevention efforts and ongoing awareness and education. In 2015 it was estimated that globally 34.0 to 39.8 million people are living with HIV. The following cartogram shows the countries of the world resized according to the adult population (aged 15-49) living with HIV, complemented by two maps showing the corresponding relative percentages:
It took a long time for humankind to move out of Africa and inhabit the rest of the planet. Archaeological research and genetic studies based on fossils found in plains of east Africa suggest that modern humans evolved nearly 200,000 years ago. Palaeontological findings and genetic footprints are also the basis for current theories of how modern humans (Homo sapiens) started spreading around the globe. Such models and timings keep changing, with new discoveries being made on a fairly regular basis.
The below map illustrates the migration of humanity across the Earth with all movement originating in Africa and with the estimated dates of arrival shown at key directions and locations. The dates are based on a number of scientifically validated estimates. They build upon the ‘Out of Africa’ model that assumes the spread of modern humans from their African origins across the globe, superseding any other human species that had lived in parts of the planet before (and sometimes as) Homo sapiens arrived.
The electorate of the United States of America has come to a decision about who is to become their next president. But not quite the whole electorate went to the polls: Turnout was at a long-term low with about 55% of voting age citizen having cast their ballot in the 2016 presidential election. Long gone are the days in which up to around 80% of the electorate went to the polls: This was last seen in the 19th century.
62,979,636 votes (46.1%) were cast for Donald Trump, while Hillary Clinton received 65,844,610 votes (48.2%). Other candidates put together reached 7,804,213 votes (5.7%). The following cartogram shows the distribution of votes for the two main candidates. Shown in diverging colours is each respective candidate who received the largest share of votes in each county. The cartogram itself shows an equal-population projection (gridded population cartogram) where each grid cell in the map is resized according to the total number of people living there. The main cartogram is accompanied by a second cartogram showing the distribution of votes that went to neither of the two candidates, and a ‘conventional’ reference map that also shows the states of Alaska and Hawaii:
