American Community Survey 2019–2023
San Marcos area census tracts by foreign-born residents
Foreign-born residents is highest in Niederwald city (south) (30.7%). This table ranks 46 eligible mapped census tracts.
Foreign-born residents values are ACS five-year survey estimates. Percentage and median rankings exclude tracts below 500 residents; this reduces but does not eliminate sampling uncertainty.
Method and source
Values come from the U.S. Census Bureau American Community Survey 2019–2023 five-year estimates. Census tracts are small statistical areas, not necessarily neighbourhood boundaries. The result is a descriptive comparison of the mapped area, not a measure of individual households or a prediction. Read about the American Community Survey.
