US Circle Max Population Challenge
DirectionsUpon clicking START you will be shown 5 circles, one at a time, with increasing radii: 50, 100, 250, 500 and 1000 miles. The object is to move the circle to the location in the US such that it covers the most amount of people, based on US census tract data. You are scored based on how many people you cover compared to the maximum possible (score is based on the ratio of people in your circle compared to max possible – score is not an exact ratio but falls faster than that).
Only population in the US counts, not Canada/Mexico.
