Value Notes
Methodology differences may exist between data sources, and so estimates from different sources are not comparable.
Some estimates presented here come from sample data, and thus have sampling errors that may render some apparent differences between geographies statistically
indistinguishable. Click the Quick Info icon to the left of each row in TABLE view to learn about sampling error.
The vintage year (e.g., V2025) refers to the final year of the series (2020 thru 2025). Different vintage years of estimates are not comparable.
Users should exercise caution when comparing 2020-2024 ACS 5-year estimates to other ACS estimates. For more information, please visit
the 2024 5-year ACS Comparison Guidance page.
(b)Hispanics may be of any race, so also are included in applicable race categories
(c)Economic Census - Puerto Rico data are not comparable to U.S. Economic Census data

FFewer than 25 firms
FNFootnote on this item in place of data
NANot available
SSuppressed; does not meet publication standards

ZValue greater than zero but less than half unit of measure shown
-Either no or too few sample observations were available to compute an estimate, or a ratio of medians cannot be calculated because one or both of the median estimates falls in the lowest or upper interval of an open ended distribution.
NData for this geographic area cannot be displayed because the number of sample cases is too small.
