Households in Somis average 2.79 people, a bit above the national 2.65, so families with children are somewhat more common here. Even so, the typical household here is smaller than in the Oxnard area as a whole, where it has 3.11 people. Since 2006–10, household size has dropped from 3.06, but in a place this small, survey estimates can swing a lot from one release to the next.

Unemployment runs a little high in Somis: 6.1% of the labor force was out of work and looking, against 5.4% nationally. That is in line with the rest of the Oxnard area. Because the Census pools five years of responses (2020–24), these rates smooth over short swings and lag the current job market.

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 Somis. 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.
