Casa de Oro-Mount Helix, CA population, income and ZIP codes

Casa de Oro-Mount Helix CDP is a mid-size town in California, with 19,651 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #354 of 1,618 ranked by population — larger than 78% of them. The median age here is 44 years against 39.1 nationally, a slightly older 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 Casa de Oro-Mount Helix CDP earn a median of $123,037 a year, 56.7% above the national figure of $78,538 and 35% 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 4.7% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Casa de Oro-Mount Helix CDP is valued at $906,500, 198.8% above the national figure and 54% above the $589,600 peer median, while median gross rent runs $1,970 a month, 40.1% above the national figure, or roughly $23,640 across a full year. A household on the local median income would put about 19.2% 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 7.4×, 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. 76.9% 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.

Home values sit at 7.4× 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.

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.
