Simi Valley, CA population, income and ZIP codes

Simi Valley city is a mid-size city in California, with 125,769 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #47 of 1,618 ranked by population — larger than 97% of them. The median age here is 41.8 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 Simi Valley city earn a median of $117,703 a year, 49.9% above the national figure of $78,538 and 29% above 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 6.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Simi Valley city is valued at $753,500, 148.4% above the national figure and 28% above the $589,600 peer median, while median gross rent runs $2,513 a month, 78.7% above the national figure, or roughly $30,156 across a full year. A household on the local median income would put about 25.6% 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 6.4×, 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. 72.9% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Home values sit at 6.4× 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
