The object of this quiz is to click on the circle containing the largest population. When you begin you'll be shown 2 circles on the map with radii between 10 and 250 miles which do not intersect. Click on the one with the larger population within it (based on US census tract info) then 'Submit' - if you are correct you'll move on. One incorrect round and the quiz is over. Every 5 rounds the number of circles on the map will increase by 1. Try to build the longest streak of correct circles. Circles displayed will always be non-intersecting.
NOTE: You may have to zoom out to see all circles, occasionally a AK/HI circle will be included. Also, only population within the US is included in the total, any Canada/Mexico coverage counts as 0 population within the circle.
I was kinda surprised by what estuarine, bayside, and soundside cities in WA and OR were included or excluded, and yet no such cities in CA were included. For instance, Hoquaim was included, but not Aberdeen. Several Puget Sound municipalities were included, but despite having an actual port that has ocean-going ships taking logs to Asia, Olympia was not. Bainbridge Island, yes. Bremerton, no.
Yeah I went by the boundary files per the directions. Also if a place is unincorporated it’s generally not included on my city quizzes… not sure if that applies to the ones you are thinking of.
I think the San Francisco coordinates are slightly off, it appears to me like its in the water here
That’s actually the centroid of the city as it has a lot of water area…I use a land based coordinate on most quizzes however.
