Quick Definitions
Concentration Index - Also called location quotient, this index is created by comparing the ratio of any economic indicator from one region to another. In the charts, the noted industry's employment share of a region is compared to the U.S. equivalent. For example, Illinois' food manufacturing concentration index is equal to the share of Illinois' food manufacturing employment (out of total employment) over the share of food manufacturing employment in the U.S. If the concentration of food manufacturing facilities in Illinois is similar or equal to that of the U.S, then the resulting concentration index would equal one. If there were a larger share of food manufacturing facilities in Illinois than in the U.S, then the concentration index would be above one and vice versa. (For further detail, please refer to Bill Testa's blog.)

Chart Construction
The charts were constructed to split regional economies into four groups. For the x-axis, the chart is centered on 1.0, to divide the concentration indices between industries of higher concentration relative to the U.S. and those of lower concentration. The y-axis is centered on the region's median industry as measured by employment size, which essentially splits the region's industries in half such that those industries with a higher number of employees would appear above the x-axis and a lower number would appear below it. The groupings of the manufacturing industries are defined according to the North American Industry Classification System (NAICS). The NAICS industries that are most prevalent in a region (both in concentration and size) are labeled. If a region has an especially notable industrial specialization (beyond the NAICS 3-digit level), it is indicated in parentheses.
