Description:Geographic concentration and disproportionality indices for 4 select fisheries in the Northeast region are constructed and examined with generalized Theil indices of geographic disproportionality. Fishing activity is alternatively measured by using monetary value and weight quantities. We use weighted relative indices to describe changes in the landing locations of individual fisheries relative to the broader fishing industry. We use weighted absolute indices to describe changes in the landing locations of individual fisheries relative to the uniform distribution across ports. These methods can be straightforwardly applied to other fisheries to describe geographic disproportionality and concentration. [doi:10.7289/V5CJ8BHX(http://dx.doi.org/10.7289/V5CJ8BHX)]
