Census 2020 in Massachusetts: FAQs

Frequently Asked Questions about Census 2020

What is the decennial census?
Every ten years, the federal government does a count of the population of the United States. 

What happens to my data? Is it safe to respond? 
By Census Law, Title 13 of the U.S. Code,  all responses to Census Bureau surveys and censuses are kept confidential and used for statistical purposes only. The Census Bureau publishes "aggregated statistics that do not reveal information about particular individuals, households or businesses." Learn more about Title 13 or review Title 13 in its entirety. Violations are a federal crime. 

In order to ensure data sets are useful and protect individual privacy, the Census Bureau will apply safeguards called “disclosure avoidance", which include “differential privacy”. Read more about data protection and privacy

Why is it important to respond to the census? 
First, it's the law! Title 13 requires that persons respond to the census.
Second, the data collected by the Census Bureau is used to to distribute federal money, distribute congressional seats, redistricting at the federal and state level. For example, in FY 16, Massachusetts received $22,849,016,142 through 55 federal spending programs guided by data derived from the 2010 Census. (See Counting for Dollars 2020 The Role of the Decennial Census in the Geographic Distribution of Federal Funds). 
After the 2010 Census, Massachusetts lost one congressional seat
