The object of this quiz is to place 20 circles of radius 100 miles on the map so that they contain the largest total population.
When you begin you'll be given a 100-mile radius circle centered on the map. Move it using the mouse and click SUBMIT. You will be given a score for that circle corresponding to the total population among all US census tracts within it (there are about 85K total US census tracts averaging about 4K people each). Try to complete all 20 circles with the highest total score.
Any INTERSECTING areas are only counted one time, so no census tract will be counted more than once.
can this be updated with newer census data?

adding time to it now.
This quiz is nearly impossible
This quiz is impossible now if you’re not a premium member. I believe you used to get a time bonus for completing a number but now the only bonus I get is at 250. There may be one at 500 but I can only get in the mid-300s now in the time provided.
