What is a location quotient?
The Bureau of Labor Statistics developed location quotients (LQs) to measure the concentration level of a particular industry in a region. LQs are ratios that allow an area’s distribution of establishment counts by industry to be compared to a base area’s distribution. In this case, the area is Los Angeles County and the base area is the United States. The industry in Los Angeles County has the same share of its establishment count as the entire United States if the LQ is equal to 1.
