Next census will be 2030.
Decennial Census (every 10 years or decade.)
There is a planning census (the 2024 Census Survey) for a result in 2025. It is administrative for testing, training and retooling for the 2030 official census. The Census Survey is not official.
Although it can be costly, it would be fantastic if there was a census every 5 years. It would better reflect the rapid changes in demographics, and the expotential growth that occurs now days.
We all know of places that have turned to pure crap in 10-20 years, and a mid-decennial count would be great for tracking what is going on... It would be very useful for planning and investment, with less sleazy manipulation.
An example of the manipulations can be seen at any boom town. When the boom is over, the greedy local politicians keep on raising fees, making higher assessments, expanding their pet projects, saddling the community with astronomic bond issues, raising local taxes... And often the data they advertise to accomplish these measures is as much as 9.5 years old.
A small boom town could go from a population of say 30,000 to 45,000 in 10 years, then begin declining shortyafter the census. The public is oblivious that the population is headed back down to 30,000 (or lower), while the local politicians, commissioners, business bureaus, chambers of commerce, and financial elites lie to them and try to milk profits at the publics future expense.
This is the main corruption that makes the boom-followed-by-bust so commonplace.
It also causes places to be hyped as booming and fantastic, but people arriving there quickly realize they've been duped.
