Every 10 years, the census is the constitutionally required count of every person living in the United States. Census data is used to make decisions about federal appropriations that communities rely upon for services and programs, including grants to states under the Library Services and Technology Act (LSTA). Our local communities also use census data for planning purposes.
This is the first census to accept online survey responses. Data collection began in remote portions of Alaska on January 21, 2020, and most households received their census materials by March 12, 2020. The COVID-19 health crisis disrupted the planned timeline for data collection, so the response period has been extended to October 31, 2020. Field operations will take place depending on when it is safe to do so.
Sno-Isle Libraries is considered a key partner in census education and outreach and is participating in both Snohomish and Island Counties' "Census Complete Count Committees".
