# Empirical View
In general in the past, when education rates rose, democratization and industrialization of the society also increased. This is also true for early European societies where democratic and industrial societies first emerged. The rise of science and the abundance of creativity that characterise modernity has roots that reach far back into the past.
# The Spread of Literacy in Europe before 1800
The social historians Buringh and Van Zanden researched this rise in education and reconstructed literacy levels for ten European countries between the middle of the 15th century and 1800. Their reconstruction shows how the rising levels of education in Europe foreshadowed the emergence of modern societies.Full screen view Download Data
In the previous graph we have seen that education levels rose quickly in the Northwest of Europe. Though the European civilizations of antiquity were centered around the Mediterranean Sea, it was northern Europe where the Enlightenment originated. England was very much at the center of the development of modernity. The following graph shows how modernization – characterized by science, technological progress, freedom and tolerance – was enabled by improving the education of ever larger shares of the population. It also shows the reduction of gender inequality in education.
# Methods for Reconstructing Early Literacy Rates
Statistics of literacy rates for recent decades are published by statistical offices. For earlier periods, historians have to reconstruct data from other sources. The most common method is to calculate the share of those people who could sign official documents (e.g. court documents), which is also the source of the previous graph. Dittmar3 notes that this only gives a lower bound of the estimate because the number of people who could read was higher than the number who could write. Allen (2003) takes a different approach and bases his estimates of literacy levels for early Europe on the level of urbanization.4
We have seen the huge gender inequalities in literacy rates in pre-modern England. Similarly to what has happened with respect to gender inequality, the modernization of the USA also brought down the inequality between races. It is also interesting to see how comparably well-educated the US population was even in the 19th century; it helps to understand why it was one of the first non-European countries that achieved economic growth and progress.

# Latin America
Illiteracy rates in Latin America have dramatically decreased in the past century; many nations have gained 40-50 percentage points in literacy during this time period. However, there is still a wide disparity between nations, as seen in the following graph.Full screen view Download Data
# The Global Picture and Developing Countries in the 20th Century
It is not easy to get an overview of the level of education on a global level for the past, but we know that for the world regions the literacy level was very low. We can infer this, for example, from the next graph that shows that even at a comparably late point (1980 depicted in the left panel) literacy levels for the population older than 50 were below 30% outside of the developed world and Latin America and the Caribbean.
But we also see that this has been rapidly changing; every younger generation is better educated than older generations. It is particularly promising that the change is happening very quickly in the least educated regions of our world. To see this, note that the slope of the lines in the least educated countries is much steeper in the least educated regions on the bottom of the graph.
In Sub-Saharan Africa in 1995, for example, the literacy rate of the youngest population group was more than three times higher than of the oldest population group. It may seem obvious, but it is still worth pointing out that in all the statistics shown here we have never seen a reversal of this positive development.
# Literacy Rates in the Present World
Literacy had a slow start in early pre-modern Europe, but it is now spreading rapidly around the world. All countries outside Africa (with the exception of Afghanistan) now have a population where more than half of the population is able to read. This is depicted in the following world map based on UN data. In many nations there is a huge difference between the literacy rates of the youth, adults and elderly. This points to a global trend: the high literacy rate among the youth indicates that as time passes, the literacy rate for the overall population will continue to increase.
The change of literacy since 1980 can be studied at the website of the World Bank on a world map, and the data can also be obtained from their database.

# Literacy in the Middle East and Northern Africa
Largely unnoticed education has dramatically improved in Northern Africa and the Middle East. Using the same UNESCO data as above the map shows that in many countries only less than a third of the older generation is literate. In contrast, often more than 90% of the younger generation is literate.
Correlates, Determinants & Consequences
# As global education improved so did global literacy
Looking at the graph below we see that in 1870 more than 3 quarters of the world’s people never had the chance to go to school. Looking at the graph at the bottom we see that this meant was that a similar small share – 19% – of the world were able to read.
The low average figure of education attendance hides huge inequality between world region. While in Europe and the Western Offshoots in North America and Oceania more than half of the population had attended school in 1870, the share was much lower in other parts of the world: In Africa and South-East Asia more than 90% of the population never went to school.
Today the global average has risen to 82% and the inequality between world regions – while still existing – is much lower.
Two centuries ago only a small elite of the world had the ability to read – the best estimate is that 12% if the world’s people were literate. Over the course of the 19th century this number more than doubled. And over the course of the 20th century the world achieved rapid progress in education. More than 4 out of 5 people are now able to read – and from the maps above we can see that it is mostly older people that are illiterate. The young generation is much better educated than ever before.
# Data Quality & Definition
According to a 1958 UNESCO resolution, literacy is defined as the ability to both read and write a short, simple statement about one’s own life. Literacy rates are determined by literacy questions in a census or sample survey of a population, in standardized tests of literacy, or via extrapolation from statistics about school enrollment and educational attainment10.
