Employment concentration varied by industry and state
In 2023, employment in air transportation was 5.5 times more concentrated in Alaska than in the United States overall. Many towns and villages in Alaska are inaccessible by road and rely on air transportation for freight and passenger transport.
In couriers and messengers, employment was most concentrated in Kentucky and Tennessee, at 2.9 times and 2.4 times the national rate, respectively. Two states had employment concentrations in truck transportation that were more than twice the national rate (Arkansas and Nebraska). The only states with more than twice the national rate in warehousing and storage were Delaware and Nevada.
In five states, employment concentrations in transit and ground passenger transportation were over twice the national rate. In three states—Connecticut, Massachusetts, and New York—this largely reflected high employment concentration in school and employee bus transportation. In Hawaii and Nevada, the high concentrations were mostly due to employment in taxi and limousine services.
Employment in support activities for transportation, at twice the national rate, was most concentrated in Louisiana. This state’s high concentration largely reflects its employment in support activities for water transportation, such as port and harbor operations and navigational services to shipping.
