Oakley city, CA in context

How this area compares with national benchmarks.

Oakley city is a small city in California, with 44,311 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #207 of 1,618 ranked by population — larger than 87% of them. The median age here is 36.4 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Oakley city earn a median of $132,067 a year, 68.2% above the national figure of $78,538 and 45% above the $91,111 median for the 1,050 California cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 6.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Oakley city is valued at $632,800, 108.6% above the national figure and 7% above the $589,600 peer median, while median gross rent runs $2,031 a month, 44.5% above the national figure, or roughly $24,372 across a full year. A household on the local median income would put about 18.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 4.8×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 77.1% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
