Waterbury, CT population, income and ZIP codes

Waterbury city is a mid-size city in Connecticut, with 114,356 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #5 of 215 ranked by population — larger than 98% of them. The median age here is 37.8 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Waterbury city earn a median of $51,642 a year, 34.2% below the national figure of $78,538 and 46% below the $96,484 median for the 159 Connecticut 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 23.9% 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 Waterbury city is valued at $185,400, 38.9% below the national figure and 46% below the $344,200 peer median, while median gross rent runs $1,180 a month, 16.1% below the national figure, or roughly $14,160 across a full year. A household on the local median income would put about 27.4% 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 3.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 45% 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.
