Location quotients are the ratio of an industry’s employment share in an area to its national share. For example, an industry with 6 percent of county employment and 2 percent of national employment would have a location quotient in that county of 6/2 = 3. A location quotient greater than 1 means the industry has a higher share of area employment than the national average.
