Westminster, CA population, income and ZIP codes

Westminster city is a small city in California, with 90,147 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #91 of 1,618 ranked by population — larger than 94% of them. The median age here is 41.7 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 Westminster city earn a median of $82,686 a year, 5.3% above the national figure of $78,538 and 9% below the $91,111 median for the 1,050 California cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 15.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Westminster city is valued at $820,000, 170.3% above the national figure and 39% above the $589,600 peer median, while median gross rent runs $2,100 a month, 49.4% above the national figure, or roughly $25,200 across a full year. A household on the local median income would put about 30.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 9.9×, 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. 52.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 9.9× 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. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
