Greenfield city, CA population, income and ZIP codes

Greenfield city is a mid-size town in California, with 19,759 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #353 of 1,618 ranked by population — larger than 78% of them. The median age here is 27.5 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Greenfield city earn a median of $78,946 a year, essentially level with the national figure of $78,538 and 13% below the $91,111 median for the 1,050 California cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 12.2% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Greenfield city is valued at $462,400, 52.4% above the national figure and 22% below the $589,600 peer median, while median gross rent runs $1,690 a month, 20.2% above the national figure, or roughly $20,280 across a full year. A household on the local median income would put about 25.7% 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 5.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 53.7% 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.

A median age of 27.5 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.
