Every 10 years all people in the USA are counted.  We do this online. It only takes a minute.

The totals affect benefits such as Medi-Cal, WIC, food stamps, school lunches, education and how our representatives are selected. When more people are counted, more money is given to each state. This 2020 census ends October 30. Please go to https://my2020census.gov/ and sign up. Your information will be private.
