The Wealthy in the USA
1) Median family income means that half the families in a tract are above and the other half are below the value shown.
2) Census tracts are relatively homogeneous units with respect to population characteristics, economic status, and living conditions at the time they are established, census tracts generally contain between 1,000 and 8,000 people, with an optimum size of 4,000 people. Census tract boundaries are delineated with the intention of being stable over many decades, so they generally follow relatively permanent visible features. The USA is divided into 26,276 rural and urban census tracts.
3) Metropolitan areas (technically, Metropolitan Statistical Area) with at least one census tract with the highest median family income category ($150,001) are mapped. MSA is a geographic entity designated by the federal Office of Management and Budget for use by federal statistical agencies. An MSA consists of one or more counties, except in New England, where MSAs are defined in terms of county subdivisions (primarily cities and towns).
