Federal funding for social services (including components of the regional center system) is generally tied to population size at the state, county or municipal level, and the way population growth is measured is through the U.S. Census, which is conducted in the first year of every new decade. It is for this reason that it is very important that everyone be counted, and that is why various public service organizations have created web resources (linked below) to help individuals with disabilities take part in this year's Census.
Census Help for Individuals and Families
Disability Rights California is working to get as many individuals with disabilities as possible to take part in the Census, and to that end, the organization has authored a succinct webpage, 4 Easy Ways to Complete the Census, that is available in 12 languages:
For additional information about the Census and why it is important, watch the series of short videos (in English, American Sign Language or Spanish) on the Disability Counts 2020 website.
Census Help for Residential Facility Administrators
Residential facilities are responsible for getting their residents counted in the Census, thus the U.S. Census Bureau has created a webpage, Group Quarters Enumeration, to help facility administrators complete the process. (The page is also available in Spanish.)
