Every 10 years, the United States government (the Census Bureau) takes a census of residents to determine how many people are living in the U.S., Puerto Rico, American Samoa Islands, Northern Mariana Islands, Guam, and the U.S. Virgin Islands. The census has been taking place since 1790. 

If you remember, in 2010, officials went door to door at people’s homes to have them fill out this census on paper. Now, in 2020, some things have changed.
