Los Alamos CDP, NM in context
How this area compares with national benchmarks.
Los Alamos CDP is a mid-size town in New Mexico, with 13,471 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #17 of 527 ranked by population — larger than 96% of them. The median age here is 41 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 Los Alamos CDP earn a median of $136,502 a year, 73.8% above the national figure of $78,538 and 153% above the $54,029 median for the 153 New Mexico 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 3.6% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in Los Alamos CDP is valued at $458,200, 51% above the national figure and 141% above the $190,000 peer median, while median gross rent runs $1,304 a month, 7.3% below the national figure, or roughly $15,648 across a full year. A household on the local median income would put about 11.5% 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 3.4×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65.9% 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.
No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
