CI:Now launches the ACS Sidekick

Screenshot of ACS Sidekick query interfaceIt’s been a long and winding road, but the ACS Sidekick is officially here! Sidekick makes it much faster and easier to process Texas data from Census American Survey 5-year estimates. It can help if you:

  • need an aggregate (total) estimate for non-standard ranges or groups not shown in the “off the shelf” ACS data. Some examples:
    • a custom geographic area, like a nonprofit service area of 17 census tracts
    • an uncommon age group, like youth aged 17-24
    • custom demographic group, like men of color
    • a specific percent of federal poverty level, like 100%-<299% FPL
  • need the margin of error (MOE) for that estimate and don’t have the time or desire to look up the formula and calculate it
  • use the same queries or value sets (e.g., those 17 census tracts in your service area) over and over for monthly reports or data for grant applications.

Registration is free but the user does need to create an account to so they can save and re-use lists and queries.

The ACS Sidekick includes:

  • ACS 2018, 2017, and 2016 5-year estimates;
  • Data for the United States as a whole; Texas as a whole; and each county, ZCTA (ZIP Code Tabulation Area), census tract, and block group in Texas; and
  • All B and C tables.

If you’re not, you’ll face a learning curve, but it’ll be worth it. In either case, we strongly recommend checking out the #protips in User Notes.

The Technical Notes include a cheat sheet of tables for common topics, plus basic information about how ACS tables are named and numbered. You’ll also find helpful information about Census geographies, ACS concepts and questions, and basic trainings on the Sidekick landing page.


The ACS Sidekick was developed for CI:Now by Jef Waltman Technology Consulting.

Support for ACS Sidekick development was generously provided by the Kronkosky Charitable Foundation, the United Way of San Antonio and Bexar County, a Community Engagement Small Project Grant from the UTHealth San Antonio Institute for the Integration of Medicine and Science, and Jef Waltman, who donated much of his time to the project. We also thank the Health Collaborative and several data users for donating their time to help us to conduct usability testing to improve the Sidekick.
