a Differences between population estimates (ABODE minus PPA) by state, differentiated by well-areas where both ABODE and PPA > 0 (blue), and where PPA predicted a population of at least 1 and ABODE = 0 (red). b frequency histogram of population method agreement type by state – counts of well-areas where PPA and ABODE both predicted positive populations (green), counts of well-areas were both methods predict zero (blue); and respective counts of confirmed false positives where PPA predicted between 0 and 1 (yellow) or greater than 1 (red) with ABODE predicting zero in both cases
