**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., V2023) refers to the final year of the series (2020 thru 2023). Different vintage years of estimates are not comparable.

Users should exercise caution when comparing 2018-2022 ACS 5-year estimates to other ACS estimates. For more information, please visit     the 2022 5-year ACS Comparison Guidance page. 

**Fact Notes**      -  (a) Includes persons reporting only one race
      -  (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
**Value Flags**      -  D Suppressed to avoid disclosure of confidential information
      -  F Fewer than 25 firms
      -  FN Footnote on this item in place of data
      -  NA Not available
      -  S Suppressed; does not meet publication standards
      -  X Not applicable
      -  Z Value 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.
      -  N Data for this geographic area cannot be displayed because the number of sample cases is too small.

QuickFacts data are derived from: Population Estimates, American Community Survey, Census of Population and Housing, Current Population Survey, Small Area Health Insurance Estimates, Small Area Income and Poverty Estimates, State and County Housing Unit Estimates, County Business Patterns, Nonemployer Statistics, Economic Census, Survey of Business Owners, Building Permits.
