US Census Data

2020 Census FAQ and step-by-step guidance to using the US Census Bureau's primary tool for accessing census data.

Finding Tract numbers

USACensus Tracts are the smallest geographical unit for which detailed Census data (income, education, poverty status, etc.) is provided.

Before you can find data at the Tract level, you must know the Tract numbers which encompass the area you are interested in. Here are two ways to find these numbers:

  • Use the Address Search box on the GeoCoder page and make a note of the Tract number, or copy it. See step-by-step directions for using this feature in the box below.
  • Use the 2010 Census Tract reference map. This database provides PDFs of Tracts for each county in the country. If you select Texas and Bexar County, the majority of the county area will be found in the map designated C48029_002. Once you've found Tract numbers in this way, use the steps in the second box below to get your data. The 2020 Census Tract reference map will be available later this year.

Choosing Tracts: When you don't know your Tract numbers

Unlike American FactFinder, Census.Data.Gov. currently doesn't have an Address Search feature that allows users to input an address and get a Census tract number. Instead, the Census data website uses a search function called GeoCoder. Users select the address option under "Find Geographies using..." header. 

A screenshot of a website. On the left-hand side, under the header "Find Geographies Using..." Option, a red arrow points at Address. On the right hand side under "Find Address" results is the address for Oregon State University

There's a lot of information returned, but towards the bottom is a header called "Census Tracts" with the Census tract name.

The Census has an FAQ available with more information on how to use this search function.
