Map: Where the People Are by Joshua Keating.
Maps created by Radical Cartography (yes, that is how I found the site) that show the distribution of the world population by latitude and longitude. Data for the year 2000.
Would be interesting to see latitude/longitude maps like this for every ten (10) years starting in about 1800.
Did the population increase in place or expand to new places? Or were there spikes of expansion followed by spikes of increased density?
