Second mapset based on my Christmas traditions survey: what kind of soup do you eat on Christmas Eve? This time people were allowed multiple answers so some places might have the most intense colors in more than one category.
It seems that beetroot soup is the most popular countrywide and present nearly everywhere, although mushroom soup and fish soup are quite popular regionally as well. Mushroom soup seems to be Christmas tradition mostly in central Poland which surprises me because there are no major woods there and mushrooms generally grow in woods. Fish soup on the other hand is popular in former Prussian territories. There is also the “other” soup category, where most of answers include fruit soup or suss which I believe is pretty much the same.

InSight World Participation Map
Over 826,923 people signed up to send their name to Mars on NASA’s InSight lander! The website where you could sign up for you ‘boarding pass’ has now been converted to show an interactive statistical map of how many people per country registered their names. Scrolling over each country procures the number of names submitted, while further down the page breaks them down by country. The top five countries were:
-United States - 260,851 -India - 57,867 -United Kingdom - 45,432 -Russia - 41,689 -Colombia - 32907 Were you one of the 826,923?
A comparison of population distribution in Poland in 1988 and 2013. Suburbanization of main metropolitan areas is visible very clearly. In addition, notice depopulation of Katowice Metropolitan Area caused by a collapse of heavy-industry and extremely low birth rates in that area.
One note: data for some areas of the country was not available, hence those blank spots in some parts of the country on 1988 map.
