Fig. 3: Trajectories in educational inequality.
From: Measuring and forecasting progress towards the education-related SDG targets
a, Trends in educational inequality are shown over time, with labels indicating the rank of inequality levels in 2030. b, Trends in educational inequality are shown with respect to mean years of schooling, with labels indicating the rank of inequality levels in 1970. Results are shown globally and regionally for every second year from 1970 to 2030, for individuals aged 25–29. The white dots mark 1970, the beginning of the estimates, 2018, the beginning of forecasts, and 2030, the SDG target year. c, National trends in the AID and mean years of schooling are shown from 1970 to 2030, with the value for 2018 shown as a bold point. The five highest and lowest values in 2018 are labelled. The solid line shows the median level of inequality for a given degree of mean years of schooling, across all years of data from 1970 to 2030, and the dashed lines show the smoothed ninety-fifth and fifth percentiles. Quantiles were calculated over modelled estimates from n = 195 countries.
