Reply to comment by Chimpskibot in [Inquirer] Census data shows Philadelphia population drop in 2022 by _crapitalism

That's some hand-waving. Like what's the typical margin of error on annual census estimates? Is it safe to say that the city lost residents this year, as opposed to gaining residents? Also, rental vacancy seems like such an indirect metric in regard to city population. Rental vacancy could mean a variety of things-- smaller household sizes, less total rentals on the market, etc.

It’s safe to say the ACS is meaningless and all policy and conclusions should be drawn from the census every decade which showed modest population gains in Philadelphia. Rental Vacancy is the best metric along with rental growth to understand population growth YOY because people need a place to live and housing pressure is directly correlated to population/income growth.

they've been getting worse and worse because the census has been estimating that all cities have been losing pop since 2017 or earlier, the 2020 census when they actually counted showed that was not true but they never updated how they're doing the estimates
