Zachary city, LA in context

How this area compares with national benchmarks.

Zachary city is a mid-size town in Louisiana, with 19,637 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #25 of 489 ranked by population — larger than 95% of them. The median age here is 34.2 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.

Households in Zachary city earn a median of $90,507 a year, 15.2% above the national figure of $78,538 and 68% above the $53,775 median for the 268 Louisiana cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 7.4% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Zachary city is valued at $258,000, 15% below the national figure and 49% above the $173,000 peer median, while median gross rent runs $1,440 a month, 2.4% above the national figure, or roughly $17,280 across a full year. A household on the local median income would put about 19.1% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 82.6% 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.
