Census Block Group Tools

Census Block Locator

HB3 requires that Texas Local Education Agencies (LEAs) report a census block group number for each economically disadvantaged student. TEA has created two tools to determine this information.

Please note that all tools listed below, the Census Block Group Calculator, Map, and API Solution, return 2010 Census Block Group numbers for student addresses for the 2021-2022 school year. The tools will be updated to return 2020 Census Block Group numbers at the end of July 2022 for the 2022-2023 school year.

Census Block Group Calculator

The Census Block Group Calculator provides census block group information for LEAs in spreadsheet format. Download the spreadsheet to find the census block group number. Download the Census Block Group Calculator Instructions PDF document to learn how to use the spreadsheet.

Calculator Compatibility

The downloadable spreadsheet is known to be compatible with Microsoft Excel 2016 and Microsoft Excel for Office 365. It is not compatible with Open Office, Google Sheets, and Excel Online.

Census Block Group Map

The Census Block Group Map provides basic information for LEAs in an interactive map format. Download the Census Block Group Map Instructions PDF document to learn how to use the map page.

This map was produced by the Texas Education Agency. It is for informational purposes only--it has not been prepared for, nor is it suitable for, legal or engineering purposes. Positions shown are based on information available at the time the map data was last updated. They are approximations, and are not the product of an on-the-ground survey.

Census Block Group API Solution

Vendors that would like to use an application programming interface (API) to retrieve student census block group numbers can use an API solution. Download the Census Block Group API Instructions PDF document for more information.
