NOTES: Resident population estimates are as of July 1 except 1980, 1990, and 2000, which are as of April 1. New metropolitan area definitions were published by the Office of Budget and Management (OMB) in 2003. These definitions were applied to population data by the Census Bureau beginning with the data from the 2000 Census. A new term, core based statistical areas (CBSAs), collectively refers to metropolitan and micropolitan statistical areas. A metropolitan statistical area is defined as having at least one urbanized area of 50,000 or more inhabitants. A micropolitan statistical area is defined as having at least one urban cluster of more than 10,000 but less than 50,000 inhabitants.

Number of immigrants is based on fiscal year data ending September 30.

Median household income and average household expenditures were converted to constant 2006 dollars using the consumer price index.
