Lafayette-area households grew faster than its population

The Lafayette metropolitan area was adding households faster than people in the years after 2020, according to HUD’s January 1, 2025 housing analysis. The distinction helps explain why housing demand can change even when population growth is modest.

HUD estimated 197,200 households in the region as of January 2025, an average increase of 1,750 a year since 2020. Household growth averaged 0.9 percent annually—three times the 0.3 percent annual population growth rate reported for the same period. HUD, pages 9–10.

Those figures cover Acadia, Iberia, Lafayette, St. Martin and Vermilion parishes together. HUD estimated their combined population at 484,800 in January 2025. The regional total does not show the direction or size of change in each parish.

The report links faster household formation partly to changes after the pandemic began, including fewer people living in dormitories. It also points to a growing older population, whose households tend to be smaller. These are HUD’s explanations of the regional pattern, rather than a count of homes needed by any one age group.

On page 10, HUD reports that people 65 and older represented about 16 percent of the area’s population in 2022, up from 12 percent in 2013, drawing on American Community Survey data. In the same discussion, it reports a 33 percent increase in one-person renter households between 2019 and 2022.

HUD also identified a change in whether additional households owned or rented. Its January 2025 analysis says renters accounted for 54 percent of household growth after 2020, while owner households had accounted for most growth during the previous decade. The estimated homeownership rate was 68 percent in January 2025.

The result is a housing picture shaped by more than arrivals from outside the region. A larger number of smaller households can require more separate homes even without a corresponding surge in population.
