In Tennessee and Virginia the name "Tri-Cities" refers to the region comprising the cities of Kingsport, Johnson City and Bristol and the surrounding smaller towns and communities in Northeast Tennessee and Southwest Virginia. All three of the principal cities are located in the extreme northeastern corner of Tennessee, while Bristol has a Twin city of the same name on the Virginia side.
The Tri-Cities region was formerly a single Metropolitan Statistical Area (MSA); due to the U.S. Census Bureau's revised definitions of urban areas in the early 2000s, it is now a Combined Statistical Area (CSA) with two metropolitan components: Johnson City and Kingsport-Bristol (TN)-Bristol (VA). As of the 2000 Census, the CSA had a population of 480,091 (though a July 1, 2008 estimate placed the population at 500,538).

All-American City Award 
The All-America City Award is given by the National Civic League annually to ten cities in the United States. In 1999, the Tri-Cities were collectively designated as an All-America City by the National Civic League.
The award is the oldest community recognition program in the nation and recognizes communities whose citizens work together to identify and tackle community-wide challenges and achieve uncommon results.
Since the program's inception in 1949, more than 4,000 communities have competed and over 500 have been named All-America Cities.
