Find Population on Map
Estimate the population within a custom-defined area on a map. By drawing a shape, selecting a radius, or inputting coordinates, users can calculate how many people live within that boundary. The tool uses population data overlays to provide real-time estimates, making it useful for planning, analysis, or research purposes. It's ideal for both personal and professional geographic population insights.
Get Started
You can search by a location name and radus, OR choose the circle / polygon icon on the toolbar and start drawing your area.

Comments
Bob, what size is the shape? There are "too small" and "too large" scenarios that will produce no results.
I keep getting error;no results when I make my own shape
Justin R, it should be working again
The auto-complete on city names is no longer working
Why doesnt 2020 work?
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 is still showing Zero for the population estimate.
It does the wrong population for Denmark
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.
Doesn't work in Finland
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.
polygon doesnt works
Estimated the population of the area where I live as 0
Data is no longer displaying as of 2.1.24 Map updates but website only states "please wait" before providing error message
