Mammoth Lakes, CA population, income and ZIP codes

Mammoth Lakes town is a mid-size town in California, with 7,233 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #566 of 1,618 ranked by population — larger than 65% of them. The median age here is 37.7 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 Mammoth Lakes town earn a median of $87,121 a year, 10.9% above the national figure of $78,538 and 4% below 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 8.6% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Mammoth Lakes town is valued at $657,000, 116.5% above the national figure and 11% above the $589,600 peer median, while median gross rent runs $1,637 a month, 16.4% above the national figure, or roughly $19,644 across a full year. A household on the local median income would put about 22.5% 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 7.5×, 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. 61.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 7.5× 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.
