Californians Are Sporting Gods

I came across ii maps today that seem to advise that Californians are the athletic giants of the United States. Business Insider created this map of the aureate medals won past times athletes from each province inwards all the modern Olympic games (since 1924).

The States With The Most Olympic Gold Medals map, at get-go glance, appears to assay that "California is the close athletic province inwards the country". This is backed upwardly past times this map of college football game players from Mode.

The Mode Where Football Players Call Home map visualize where college football game players come upwardly from. The map sure shows that a lot of college footballers come upwardly from California.

However both these maps are practiced examples of why yous should normalize for population when creating these form of heatmaps. California is the close populous province inwards the USA. Therefore if nosotros do whatsoever form of heatmap, whether for crime, the close millionaires or the close people living inwards poverty, if nosotros don't normalize for population density thus nosotros would facial expression California to charge per unit of measurement fairly highly - precisely because it has the close people.

In fact later on a quick search on Google I flora this obesity heatmap of the USA. So nosotros directly honour ourselves inwards the foreign province of affairs where Californians are at the same fourth dimension both fat together with sporting gods.

Actually the Where Football Players Come From map does allow us to sentiment a 'per capita' map. Here's the map for the release of college footballers from each province later on the information is normalized for population.

Perhaps Californians aren't such sporting gods later on all.
