Frequently Asked Questions
What is the US Census ACS survey?▾
The American Community Survey (ACS) is an ongoing survey conducted by the US Census Bureau. Unlike the decennial census, it's conducted every year and provides detailed demographic, social, economic, and housing statistics. The 5-year estimates used here pool data from 5 years of surveys for greater statistical reliability.
How is median household income calculated?▾
Median household income is the middle value of all household incomes — half of households earn more, half earn less. It includes wages, salaries, self-employment income, and other income sources. It's considered more representative than average income because it's less affected by extreme high-income households.
Where can I find city-level demographic data?▾
You can find city-level data for South Carolina by browsing the individual city pages on this site, or by visiting the US Census Bureau's data.census.gov portal directly. The ACS collects data for cities, counties, zip codes, and census tracts.
How often is demographic data updated?▾
Census Bureau ACS data is updated annually, typically released about 12-18 months after the reference year. The 5-year estimates are the most reliable for small areas and smaller population groups. Decennial census data is collected every 10 years (last: 2020).
