Fig. 1: Average multiple sustainability and gap indicator scores for 2010 and 2020.
From: The effects of China’s poverty eradication program on sustainability and inequality

The sustainability and gap indicator values ranged from 0 to 1, with sustainability indicator values closer to 1 indicating greater sustainability and gap indicator values closer to 0 indicating greater equality. The more positive the gap indicator values, the more advantages the poverty-stricken counties had compared with the non-poverty-stricken counties, while negative gap indicator values indicated that the poverty-stricken counties lagged the non-poverty-stricken counties.
