ZIP code 94037

ZIP 94037 is a small town in San Mateo County, California, with 2,897 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #1228 of 1,803 ranked by population — larger than 31% of them. The median age here is 56 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 94037 earn a median of $201,367 a year, 156.4% above the national figure of $78,538. 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 ZIP 94037 is valued at $1,467,400, 383.7% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 7.3×, 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. 89.5% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Home values sit at 7.3× 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. A median age of 56 puts ZIP 94037 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

The Census withheld gross rent for ZIP 94037 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

ZIP 94037 is tabulated inside San Mateo County, California, one of 30 ZIP areas the Census publishes for that county and 1,803 across California. Population sits in the small-town band, typically one main street plus the addresses that feed into it. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 94037 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 94037 reports a median household income of $201,367, 12% above the $179,754 county median, and 124% above the $89,916 typical CA ZIP. Owner-occupied homes are valued at a median of $1,467,400, close to the county figure and 133% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published a month, which is why it reads higher than the advertised rent on a listing for the same unit.

California charges 7.25% statewide, and local governments overlapping 94037 may add county, city or special-district levies on top. We publish the state floor for this ZIP rather than guessing a combined figure, because ZIP boundaries and taxing-district boundaries were drawn for different purposes and do not line up.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 94037 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
