| Change | −2.6 | +1.7 | +1.5 | +2.3 |
California is young: half of its residents are under 32.9, compared with a national median of 40.1. The population tilts toward young adults and children. Since 2006–10, the median age has dropped from 35.5, but in a place this small, much of that may be survey noise rather than real change. Few Louisville neighborhoods are younger: only three of 44.

| Change | −0.3 pts | −1.9 pts | −1.6 pts | −1.8 pts |
Vacant homes make up 29.9% of the housing in California, far above the national rate of 9.6%. In resort and lake areas that usually means seasonal and vacation homes; elsewhere it can point to weak demand. Only one other Louisville neighborhood has a higher vacancy rate.

| Change | +6 | +5 | +5 | +6 |

Of Louisville's 44 neighborhoods, only three have lower rents.

| Change | −3.2 pts | −3.6 pts | −3.3 pts | −2.7 pts |
Unemployment in California runs well above the national rate: 16.9% of the labor force was out of work and looking, against 5.4%. Few Louisville neighborhoods have higher unemployment: only three of 44. Because the Census pools five years of responses (2020–24), these rates smooth over short swings and lag the current job market.
Unemployment: people looking for work as a share of everyone working or looking. Source: BestNeighborhood calculations from U.S. Census Bureau ACS 5-year block-group estimates (table B23025).

About these numbers
Every figure on this page is a BestNeighborhood calculation from the Census Bureau's American Community Survey (ACS), built up from the Census block groups that make up California. Each ACS 5-year release pools five years of responses; this page shows the last 15 releases, 2006–10 through 2020–24. Neighboring releases share four of their five years, so they move gradually and small changes between them are within the survey's margin of error; in small places the lines can jump from one release to the next for the same reason. The maps show the same measures for each neighborhood, ranked against the whole country.
