Grand Terrace, CA population, income and ZIP codes

Grand Terrace city is a mid-size town in California, with 13,069 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #432 of 1,618 ranked by population — larger than 73% of them. The median age here is 37.2 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.

Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area.

A household on the local median income would put about 25.6% 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 5.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 61% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
