Is Jefferson County's population growing?

The county has lost 0.16 percent of its population since the 2020 census base. Deaths exceeded births in 2024 and the population still grew, so all of the growth came from people moving in. A market held up by migration is more sensitive to a change in relative cost than one growing from household formation.
