I work in municipal government. We pretty much ignore the 2020 census where we legally can. It was a shitshow that was intentionally sabotaged. With the while country on lockdown for several months, it should have been the most precise census ever, but Trump had to fuck it up like everything else he touches.

We do our local estimates based on number of housing units and the demographics of the type of housing (e.g. houses that cost 5 million dollars have fewer occupants per bedroom than $200,000 homes).
