# ZIP code 37048 demographics

Canonical: https://olympus.new-odyssey.com/data/zip/37048

ZCTA 37048 is the Census Bureau's ZIP Code Tabulation Area for ZIP code 37048, mostly in Sumner County, TN. In the American Community Survey 5-year estimates for 2020-2024, its median household income is $100,446 (±$13,174) and its total population is 6,380 (±715).

Margins of error are at the 90% confidence level. The figures describe 2020-2024 (dollars in 2024 dollars), not the present. A ZCTA approximates, but is not the same as, the area a USPS ZIP code delivers to.

Notes:

- ZCTAs are Census statistical areas that approximate USPS ZIP code delivery areas; the code was matched to the ZCTA with the same code, which may not cover the same addresses as the ZIP code.
- Values are ACS 5-year estimates for 2020-2024 (dollars in 2024 dollars), not current figures.
- ZCTA-county overlaps come from the Census 2020 relationship file and use 2020 counties, by land area; Connecticut uses its legacy counties, not the planning regions in ACS 2022+.
