You can respond online at https://2020census.gov/
Or fill out the form that was left at your dwelling (both residents and seasonal camp owners need to respond).
If you do not respond, the Census Bureau will be sending Enumerators to each residence for which they have not obtained a response to connect with and assist the resident in completing the census. The timing of this operation will be conducted so as to ensure public and team safety as related to Covid 19. I will keep you informed.
