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 radius, OR choose the circle / polygon icon on the toolbar and start drawing your area.

Please add an option to key in coordinates, that'll make it so much easier!
It just keeps saying "please wait" even after like 10 mins
City names are not auto populating
I keep getting zero for population estimate
I get 0 as estimated population, how come?
Legit, yes. Accurate, subjective, but treat it as an estimate.
it this legit ? and accurate
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.
