Thousand Oaks, CA population, income and ZIP codes

Thousand Oaks city is a mid-size city in California, with 125,676 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #48 of 1,618 ranked by population — larger than 97% of them. The median age here is 44.5 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Thousand Oaks city earn a median of $134,367 a year, 71.1% above the national figure of $78,538 and 47% above the $91,111 median for the 1,050 California cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Thousand Oaks city is valued at $951,200, 213.5% above the national figure and 61% above the $589,600 peer median, while median gross rent runs $2,580 a month, 83.5% above the national figure, or roughly $30,960 across a full year. A household on the local median income would put about 23% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 7.1×, against roughly 3.9× nationally, so buying is out of reach on local earnings alone and the ownership market leans on outside income, equity or dual high earners. 70.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 7.1× median household income, far past the 3.9× national mark, so ownership costs here are set by something other than local wages — second homes, retirees with equity, or commuters earning elsewhere.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
