Circular Area Profiles (CAPS) - ACS Version

Revised Version (December, 2016) Now Using 2011-2015 Data

This application will aggregate 2011-2015 American Community Survey data to approximate circular areas as specified by the user using a point location and 1 or more radius values. Data used are from the latest tract or block group level 5-year period estimates, standard MCDC extract. Some data items are not available at the BG level.

Looking for more reliable basic demographic data for smaller radii? See our caps10c application that works with data from the 2010 census.

Want to get more reliable estimates for smaller radii?

Try our caps16acs (beta) version that employs an improved method for estimating circular areas.

Interested in getting data for a large number of sites? Have a look at ALPS, our Address List Processing System (fee-based batch services).

See the Usage Notes for background information and instructions on how to use and interpret the results of this application.

Enter coordinates for the site in decimal degrees: Use (click on) to get Lat/Long coordinates.
Latitude:   (or, enter 5-digit ZIP/ZCTA code)
Longitude (west assumed):   (dd.mm.ss format may be used for minutes & seconds)
(Optional) Enter a name for your Site:
Enter up to 5 radius values, separated by blanks, in ascending order: (Required!)
NOTE: We do NOT recommend using a radius of less than 3 miles. If you do, then the app will use block group data to do the estimates and there will be about a third of the variables not available. When the smallest radius is at least 3 miles then census tracts are used to estimate the circle. It is not unusual to have no data for smaller radii, especially in rural areas.
(Optional) Select one or more states and the program will limit its data search to just those states.
Select the demographic profiles of interest: Demographic     Economic     Social     Housing    
Uncheck to suppress auxiliary report showing county pops within circle(s)
Check to see detailed geographic units within circle(s) report.
