The U.S. Census Bureau is hosting a pre-release webinar ahead of the embargo of new 2017-2021 American Community Survey 5-year Selected Population Tables and American Indian and Alaska Native Tables. The webinar will show participants how to access data through data.census.gov for American Indian and Alaska Native tribes, as well as for hundreds of detailed race, Hispanic origin, tribal and ancestry populations at multiple levels of geography, including census tracts. These tables allow for an in-depth look at populations beyond those covered in the annual one-year and five-year American Community Survey products.
