The map above, titled An Entirely New & Accurate Survey Of The County Of Kent, With Part Of The County Of Essex was created by William Mudge in 1801 and is regarded at the first official Ordnance Survey map.
The map above shows what Asia would look like if population density corresponded to physical elevation.
Perhaps one of the most interesting things to note, is that the Himalayas are still there, they’ve just moved south a little bit, as these regions of Indian and Bangladesh have extremely high population densities.
The map above shows the Jewish population of Europe in both 1933 and 2015 by country. Most countries still had much lower Jewish populations in 2015 compared to 1933.
This is largely due to the long lasting effects of The Holocaust, when over six million European Jews were systematically murdered by Hitler and the Nazis.
Emigration to both Israel and the United States after World War 2 and again after the collapse of Communism in Eastern Europe in 1989, also contributed somewhat to the decline.
However, not all countries saw their Jewish population decrease.
