The Census Bureau's Application Programming Interface (API) is a tool that you can use to access American Community Survey (ACS) data more efficiently. It reduces the need for data storage and provides users with a set of standard commands to easily access statistics that can be incorporated into their programs and applications. You can also use it to create simple queries to access ACS data through an internet browser. Learn more about how to access ACS datasets via the API, as well as resources to learn more about using the API.
Due to the impact of the COVID-19 pandemic, the Census Bureau changed the 2020 American Community Survey (ACS) release. Instead of providing the standard 1-year data products, the Census Bureau released experimental estimates from the 1-year data. They are posted on the 2020 ACS 1-Year Experimental Data Release page; they are not available on data.census.gov or the API.
In this tutorial, we’ll show you how to get data for an entire table from the ACS. We will walk you through the steps using DP03 from the 2019 ACS 1-year estimates for all metro areas.
In this tutorial, we’ll show you how to get data for only the variables you need from the 2019 ACS 1-Year Data Profiles, using all Congressional Districts in California as an example.
