IMPORTANT NOTE: For those of you getting "The estimated population in the radius is 0"... to "fix"/help this issue, just make the radius of the circle to SMALLER than 70km^2 at a time. Sometimes it works for bigger radiuses, but often it doesn't; also, if your circle goes across multiple different countries, it can also mess up the tool. Hope this helps!

cool app i like the idea very much but it is SO SLOW and laggy takes way too long plus when i finally outlined my area and pressed find population i waited for like 5 minutes and it just said "please wait" the whole time and never loaded

This is great. Just what I need for a study that I am doing around certain population centers.

This is fantastic. Just what I need for a study of populations related to trails around the centers of certain cities that I am doing. Thank you.

It does the wrong population for Denmark
By Panya on 27th June 2024

is still broken, only giving me a population of zero

Draw radius, clicked "Find Population" and continue to get "The estimated population in the radius is 0 Zero" as Output. Attempted multiple areas and defined radius manually and drew radius - nothing works.

this is amazing.. is there a way to bulk upload - i need to check the population around 50+ locations?

This is such a great idea and it would be a wonderful resource but drawing a circle in 250 mile radius around Washington, D.C. tells me there are zero people there.

Out of the three free population discovery services I could find (NASA SEDEC,etc and this), none of them could offer a Google Maps overlay. They all use OSM. I feel like the former offers more detail. In future I wish that you would consider adding a Google Maps overlay

Works great!

I am glad to see the recent update and changes on this website. The data is really accurate and it is really easy to use once you get to know it. Keep up the good work!
