7.6 billion people producing an estimated global GDP of 131 trillion dollars (measured in purchasing power parity), that is the world in 2018. In its latest forecast, the International Monetary Fund predicts predicts a continuing global economic growth of 3.9%, while according to the United Nations Population Division an extra 83 million people will populate this planet (1.9% growth). The following two cartograms show, how the distribution of wealth and people looks this year by resizing each country according to the total number of people (top)/GDP output (bottom):
Sometimes referred to as the fourth dimension, time has a highly geographical relevance. For human geography, population sizes can have as much impact on the ‘tempo of places’ as culture or even climate. In physical geography, the concept of time is indispensable for an understanding of how the natural environment has changed and keeps changing.
In the 21st century, time has been described as being a commodity itself, affecting everything from manufacturing and trade, to financial flows and global transport links.
The general geographic distribution of time zones is based on the general concept of dividing the world into zones of equal time following a 24-hour day around the world. In theory, this means that there are 12 time zones of 15° width in which each differs by one hour’s time difference.
The necessity of time zones was closely linked to growing needs of transport and communication links during industrialisation. British railway companies began adopting Greenwich Mean Time (GMT) which helped to coordinate timetables. In 1880, GMT became standard across Britain and time differences of tens of minutes between cities in the country started vanishing. At a global level, time zones became established in the first decades of the 20th century.
NASA’s recent release of a new Earth at night composite image is the first release of a new global map of night light distribution since 2012. Since their previous release, NASA has worked on an improvement of the underlying algorithms that provide clearer and more accurate imagery from the raw satellite data.
The latest version (shown as a small inset map in this cartogram feature) is not only the most accurate picture of light intensity around the globe, but the underlying data also allows a direct comparison of the changes that occurred between 2012 and 2016. For achieving this, the datasets of the two years were corrected for the changing light effects caused by the moon as well as “seasonal vegetation, clouds, aerosols, snow and ice cover, and even faint atmospheric emissions (such as airglow and auroras)” which “change the way light is observed in different parts of the world”. Both datasets also cover the period of a full year to take seasonal changes into account.
The following cartogram series provides a detailed look into the changed political landscapes in Germany following this year’s general election. While the previous maps gave an insight into the strongest party in each constituency, these maps give a clearer picture of the vote share distribution that also determines the constitution of parliament which follows a system of proportional representation.

The re-election of Angela Merkel as chancellor of Germany in yesterday’s federal election (Bundestagswahl) came as little surprise. Yet the final result was still widely seen as a political earthquake. The extreme right ‘Alternative for Germany‘ (Alternative für Deutschland, AfD) entered the federal parliament (Bundestag) with 12.6% of the second vote (Zweitstimme) that determines the proportional distribution of seats (having gained 7.9% compared to the 2013 election). With 94 seats, the party has become the third largest after CDU (26.8%, 200 seats, having lost 7.4%) and SPD (20.5%, 153 seats, having lost 5.2%). FDP re-entered parliament with 10.7% of the second vote (up by 6.0%, 80 seats). Former opposition leader Die Linke went up by 0.6% to 9.2% (69 seats), followed by Grüne at 8.9% (67 seats, having gained 0.5%). CDU’s sister party in Bavaria, CSU, lost 1.2% and is at 6.2% (46 seats).
AfD’s rise is the most significant change in the political landscape which also becomes visible on the new electoral maps of this year’s election. The following two maps show the distribution of the largest party in the first and second vote. In the southern parts of east Germany (Saxony) AfD managed to win three constituencies with the first-past-the-post first vote, and also became the largest party in eight constituencies in the second vote that decides on each party’s proportional representation in parliament.
Apart from this change, the electoral landscape of the strongest party in each constituency remains similar to previous elections: SPD, despite their losses, remains strongest in the urban areas of north-, central- and western Germany and are stronger in the constituency vote, while CDU dominates rural regions and much of Southern Germany except for Bavaria where CSU is taking CDU’s role. Die Linke only becomes visible as a winner in East Germany, while the Green Party holds on to its only constituency seat in Berlin:
