Cerrado area, drivers of land-cover change and welfare indicators in the north of Minas Gerais state, Brazil, for the years 2000 and 2015. Statistically significant differences (p < 0.05) are in Italic. Average values for 89 municipalities were calculated for each variable (±s.e.) and values at regional level are given in parentheses. The Gini Inequality Index and the Human Development Index (for income only; IDH-R) are not available at the regional level.
