This paper uses a unique dataset on the migration of young adults between commuting zones to analyze the most common origins and destinations of Chattanooga’s young adult migrants. Many more young adults moved into Chattanooga than moved out of it, but Chattanooga’s net in-migration rate was much lower than those for large areas such as Nashville and Atlanta. Generally, there was a hierarchy of migration according to area size: Chattanooga received many more young adult migrants from small areas nearby but sent many more to large areas both near and far away. Parental income was strongly related to the likelihood of migration and the destinations and origins of Chattanooga’s young adult migrants.
