Subjects Planned for the 2020 Census and ACS

By law, the Census Bureau must deliver decennial census subjects to Congress three years before Census Day. In March of 2017,  the U.S. Census Bureau delivered its planned subjects for the 2020 Census to Congress, which include gender, age, race, ethnicity, relationship and homeownership status. 

On September 28, 2017 the Census Bureau released this statement on planned sexual orientation questions. On January, 26, 2018 the Census Bureau released this statement on planned race and ethnicity questions. Also in January of 2018, the Justice Department asked the Census Bureau to reinstate a question about citizenship (last asked in 1950) on the 2020 Census which is a controversial issue. 

How to Look up Census Tracts

Census tracts are small, relatively permanent statistical subdivisions designed to be relatively homogeneous with respect to population characteristics.

I recommend the Federal Financial Institutions Examination Council, FFIEC, Geocoding System for determining census tract. This site helps financial institutions meet their legal requirements to report information on applications. 

Each location will have a state code, a country code, and a tract code as listed on the screen shot below. For the census tract where AU is located the full number is 11-001-000901. We drop the leading zeros and add a decimal before the next zero so the tract is 9.01
