If you need to find the median household income for latitude/longitude coordinates in bulk, you can upload a spreadsheet or use the Geocodio API.
This data is at the Census Block Group level (not the individual household).
This data is for the Census Block Group. It is not for the individual household. In order to receive accurate data, you must supply a street address, intersection, or coordinates.
The first step will be to organize the lat/lon pairs into a spreadsheet. Your spreadsheet will need to have headers. The coordinates can all be in one column or in multiple columns as long as it is consistent for the entire spreadsheet.
You can also download an example spreadsheet here. The coordinates should all be in the US.
Once your spreadsheet is organized, you can upload it directly to Geocodio. After confirming the columns and seeing a preview of the file on a map, you will be presented with options to append data. You will want to check the box that says “Census ACS Economics.” This will automatically check the box next to ‘US Census Identifiers’ and you can choose the Census year.
Results are billed as geocode + ACS Economics info (i.e., two lookups). For example, if you have 100 addresses that you want Census ACS economics data for, that would count as 200 lookups. You can calculate how much this will cost you and how long it will take here.
You will receive an email when your spreadsheet is done processing -- no need to stay on the page. You can download an example spreadsheet of addresses with Census household income data added here.
