Everyone should have received a mailing from the Census Bureau at their home, if they get mail there, or at their Post Office box otherwise. Census Day was April 1st and so far less than 50% of Clacakamas County has responded.
It is a requirement of federal law that everyone respond to the Census. It determines how many Representatives we have in Congress. It helps determine Congressional districts. Perhaps as importantly, it determines how much money Oregon and Clacakamas County get from the federal government.
This time around it’s very easy to respond. Since federal law requires everyone be counted, if you don’t respond online, the Census Bureau will hound you until you do.
