With Geocodio, you can match addresses or coordinates to the Census Bureau's American Community Survey data for average income levels. You can add it to your spreadsheet by selecting "economics" in Step 4 of the upload process, or use our API.
This data is not for the individual household. It is for the Census Block Group. In order to receive accurate data, you must supply a street address, intersection, or coordinates.
This data is provided at the Census Block Group level and is available from the five-year American Community Survey, last published in 2019. (The 1-year American Community Surveys do not have granularity at this level.)
You can download an example spreadsheet of addresses with Census household income data added 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.
