Sources and processing

This data is based on the following sources

Using the estimates on school enrollment and population structure, Barro and Lee have constructed projections of educational attainment for the population, disaggregated by gender and age group (15–24, 25–64, and 15–64) for 146 countries from 2015 to 2040 at five-year intervals.

They first use the 2010 data on educational attainment by age group as benchmark figures to project the educational attainment of the population by age group for the next three decades. They then estimate the distribution of educational attainment for the younger population, aged 15-24, at the five-year intervals from 2015 to 2040 and then forward-extrapolate the estimates to construct the distribution of educational attainment for the older population groups. For the population structure, they use existing U.N. projections. For the detailed explanation of the estimation method, see Barro and Lee (2015, chapter 3).

Barro, Robert J. and Jong-Wha Lee, Education Matters: Global Schooling Gains from the 19th to the 21st Century (Oxford University Press, 2015)

Datasets on estimated school enrollment ratios from 1820 to 2010 and estimated educational attainment for the total, female, and male populations from 1870 to 2010. The estimates are available in five-year intervals for 111 countries.

Datasets were last updated in 2021 September. The research provides insightful analysis on the progression and trends of educational attainment over a long historical period, offering a comprehensive understanding of educational developments globally.

How we process data at Our World in Data

All data and visualizations on Our World in Data rely on data sourced from one or several original data providers. Preparing this original data involves several processing steps. Depending on the data, this can include standardizing country names and world region definitions, converting units, calculating derived indicators such as per capita measures, as well as adding or adapting metadata such as the name or the description given to an indicator.

At the link below you can find a detailed description of the structure of our data pipeline, including links to all the code used to prepare data across Our World in Data.

Notes on our processing step for this indicator

Historical data up to the year 2010 has been sourced from 'Human Capital in the Long Run' by Lee and Lee (2016). This historical data was then combined with recent projections provided by Barro ane Lee (2015).

Regional aggregates were computed by Our World in Data through yearly population-weighted averages, where annual values are proportionally adjusted to emphasize the influence of larger populations.
