Louisiana is one of 7 states with union membership under 5%. How concentrated is union membership? Note this quote
Over half of the 14.8 million union members in the U.S. lived in just seven states (California, 2.4 million; New York, 1.9 million; Illinois, 0.9 million; Pennsylvania, 0.8 million; Michigan 0.7 million; and New Jersey and Ohio, 0.6 million each), though these states accounted for only about one-third of wage and salary employment nationally.
