Two Census sources power the site
Neighborhood Insights relies on two main Census sources. The estimates come from the American Community Survey 5-Year Detailed Tables for 2018 through 2024. The boundaries come from TIGER/Line geography files.
ACS provides the numbers shown across the site, while TIGER/Line provides the map boundaries for states, counties, places, and metro areas. For a plain-English guide to those geography types, see our Census geography guide.
Neighborhood Insights also applies proprietary methodology and standardization so those public Census sources can be shown consistently across the site.
The ACS tables behind the main site metrics
Neighborhood Insights shows more than one kind of number. Some measures describe the people in an area. Others describe households or housing. The table below lists the ACS detailed tables behind the main metrics used across the site.
The wording here follows the latest official Census documentation for the 2024 ACS 5-year release, even though the site's time series spans 2018 through 2024.
