The COVID-19 pandemic virus and legal challenges relating to the 2020 Census were responsible for the Census Bureau adjusting the date for responding to the 2020 Census on several occasions which delayed release of the data initially scheduled for release in late 2020.

Notable Observations of the 2020 Census

For the first time in the history of the Decennial Census, residents could choose to respond online, by phone, or by the traditional paper Census questionnaire, making the 2020 Census the easiest and most accessible Decennial Census since its beginning in 1790.

The COVID-19 pandemic virus was responsible for the U.S. Census Bureau adjusting the date for responding to the 2020 Census on multiple occasions from its initial point of reference date of April 1, 2020.

The U.S. Supreme Court, on October 13, 2020, issued an order requiring the 2020 Census self-response and field data collection operations (i.e., the population count) to end on October 16, 2020, irrespective of any other previously adjusted date.

The U.S. Census Bureau engaged in a multi-million dollar media campaign encouraging residents to respond to the 2020 Census.

The two most often mentioned reasons for conducting the Census are (a) population data plays a significant role in determining the allocation of federal and state funding for important community services and facilities, and (b) population data also determines representation in the U.S. House of Representatives (i.e., apportionment was the original legal purpose of a Decennial Census) and in establishing voting districts.
