Hello there, 

So I have 3 layers 

250 datapoitns with Cordinates

Circle I need to draw

US Census Tract layer ( I need to use this layer for this particular analysis) 

 

My objective is draw a circel of say 100km radius around each of these points and summarize the population of all the census tracts that are under it. 
Current solutuon: Insert tab - Distance and direction, then I manually have to draw a circle with a center point. Then I can summarize within the Circle I drew and the Cencus Tract layer. 

Since I have to do this manually for 250 points, I was wondering if there was a way to automate atleast parts of this. 

Like drawing the ciccles automatically using the Datapoints as centers.

Use the Buffer tool on your points with 100km as the buffer distance. That should give you the circles.

Then use Apportion Polygons on the buffer polygons and census tracks to get the summarized population.
