To determine the largest employer in each state, 24/7 Wall St. reviewed the most recent employment figures for nonprofits and private and publicly held companies using company press releases, government data, business journals, local media reports, as well as statements from company representatives. For the purposes of our analysis, we treated some state government employers like employees of public universities as independent organizations separately, in keeping with how states frequently identify and compare company headcounts. Military bases were excluded from the list. In some cases, the employment count of a hospital network primarily located in a state included a small portion of out-of-state employees. If the network was determined to be mostly in-state, we kept the total employment figure when a state-specific employment count could not be determined. In those cases and some others, the values included are listed as estimates. It should be noted that many employers do not publish employment counts, the companies listed are our best estimates based on research and publicly-available information.
