Theil Index: All West Coast Communities

The index estimates the difference between observed revenue concentrations and what they would be if they were perfectly equally distributed across ports; higher values indicate greater concentration in a subset of ports. We calculate the Theil Index for total fisheries and for specific management groups, at the scale of the 21 port groups previously established for the economic Input-Output model for Pacific Coast fisheries (IO-PAC; Leonard and Watson 2011).Theil Index and annual commercial fishery revenue data provided by K. Norman, NMFS/NWFSC, and A. Phillips, PSMFC, with data derived from PacFIN (pacfin.psmfc.org).; Additional Calculations: As a potential indicator to track progress toward meeting NS-8, we use a metric called the Theil Index to assess geographic concentration of fishing revenues.
