Did you add a comparison area but want to edit your first selection? Use “Edit Comparison Area 1” to go back and revise your first selection. You can then go back to your second comparison area by using “Edit Comparison Area 2.” When finished, click on View Profile! To completely start over, use the “Start Over” button.
Make sure you have clicked on the “View Profile” button to display your data after you are finished making your selections. You must also choose an area within the borders indicated in red. If there are fewer than 100 households in your selected area, no data will appear; we suggest you expand your area.
A custom area selection falling below a 1,500 housing unit threshold will default to 2010 Census data rather than more recent American Community Survey data. The margins of error in American Community Survey data would be too large at such a small geographic scale.
You can do this by printing the profile and map directly from your browser. Or, click on the “Bookmark or share this profile” link below the map, which will generate a unique URL that you can save, share or return to later. Please note: The data tables will display, but the map will not. To retain the custom map, we suggest you take a screenshot before clicking the bookmark link. Or, right click the bookmark link to copy it directly or open it in a new tab, leaving your original map and data table in their own tab.

The data used in the map is American Community Survey (ACS), Excensus, LEHD, or 2010 Census data. American Community Survey data is calculated using Census tracts as the base level of geography. Because small geographic areas, such as communities and neighborhoods or custom drawn areas, do not conform to Census tracts, the custom mapping tool takes this nonconformity into account and calculates an allocation ratio based on the portion of the census tract(s) within a selected area. The allocation ratio is developed by determining the percent of the population or housing units within a Census tract or tracts that fall within the selected area. The data within the selected area are then summed to produce aggregate results. No allocation ratio is needed for Excensus, LEHD, or 2010 Census data because these data are either estimates or provide a total count of the population.
