 About datasets used in this table
 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.

-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. 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.
