Demographics (Census)

With Geocodio, you can match addresses or coordinates to the Census Bureau's American Community Survey demographic data.

This data is provided at the Census Block Group level and is available from the most recent five-year American Community Survey, which is currently the 2021 survey results published in 2022. (The 1-year American Community Surveys do not have granularity at this level.)

This data is for the Census Block Group. It is not for the individual household. Please note, you must provide either street + ZIP, street + city + state, an intersection, or coordinates in order to receive Census results back. We do not provide this data for ZIP codes or city/state pairs. (If your data contains locations without street addresses, you will not be charged for the data append for those locations.)

You can download an example of the results when you add Census demographics to a list of addresses here or latitude/longitude coordinates here

We provide the data exactly as it is packaged by the Census Bureau in the breakouts it gives. The only change we have made is to add a "percentage" calculation to aid ease of use.

The data returned includes the following data points. For each data point, the data returned includes the value, margin of error, and percentage.

  • Total (Table #B01002)

    • total, male, female
  • Population by age range (Table #B01001)

    • Broken out by male and female
    • under 5 years, 5-9 years, 10-14 years, 15-17 years, 18-19 years, 20 years, 21 years, 22-24 years, 25-29 years, 30-34 years, 35-39 years, 40-44 years, 45-49 years, 50-54 years, 55-59 years, 60-64 years, 65-69 years, 70-74 years, 75-79 years, 80-84 years, 85 years and over
  • Sex (Table #B01001)

    • total, male, female
  • Race and ethnicity (Table #B03002)

    • Broken out by not-Hispanic or Latino and Hispanic or Latino
    • Not Hispanic or Latino, white alone, black or African American alone, American Indian and Alaska Native alone, Asian alone, Native Hawaiian and Other Pacific Islander alone; some other race alone; two or more races; two or more races: two races including some other race; two or more races: two races excluding some other race, and three or more races

We recognize that age, sex, gender, race and ethnicity are sensitive subjects. Accordingly, we return the categories exactly as the Census Bureau provides. We recognize that the categories listed may not be all-inclusive or use preferred terminology.


Requests are billed as geocode + ACS Demographic info (i.e., two lookups). For example, if you have 100 addresses that you want Congressional contact information for, that would count as 200 lookups.

You can calculate how much this will cost you and how long it will take here.
