Darby, PA population, income and ZIP codes

Darby borough is a mid-size town in Pennsylvania, with 10,664 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #79 of 2,002 ranked by population — larger than 96% of them. The median age here is 35.7 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 Darby borough earn a median of $45,128 a year, 42.5% below the national figure of $78,538 and 37% below the $71,118 median for the 982 Pennsylvania 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 31.5% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Darby borough is valued at $101,900, 66.4% below the national figure and 47% below the $193,200 peer median, while median gross rent runs $1,337 a month, 4.9% below the national figure, or roughly $16,044 across a full year. A household on the local median income would put about 35.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 49.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Darby borough is the unusual combination of expensive to rent and cheap to buy: rent takes 35.6% of median income while homes cost only 2.3× it. Where that pattern shows up, the gap is normally down to down-payment and credit barriers rather than price.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
