National literacy trends, 1985-2015

The report Adult and Youth Literacy: National, Regional and Global Trends, 1985-2015 by the UNESCO Institute for Statistics (UIS) provides literacy data for 151 countries for the years since 1985. In addition to historical data, the UIS report contains projections for 2015, the target year of Education for All and the Millennium Development Goals. Regional trends in adult literacy were discussed previously on this site. This article takes a closer look at national trends in adult and youth literacy.

Figures 1 and 2 present all national literacy data from the UIS database for the period 1985 to 2015 by region. Each line represents the data for one country. Single markers mean that only data for one year was available for a country. The first eight segments of each figure contain data for the countries within each region: Arab States, Central and Eastern Europe, Central Asia, East Asia and the Pacific, Latin America and the Caribbean, North America and Western Europe, South and West Asia, and sub-Saharan Africa. The "World" segment combines the data from all regions. In both figures, national trendlines are color coded according to the level of the earliest available literacy rate to facilitate distinguishing between individual countries and identifying the difference between the earliest and latest value for each country.

A comparison of adult literacy rates (for the population aged 15 years and older) in Figure 1 and youth literacy rates (for the population aged 15 to 24 years) in Figure 2 shows that youth literacy rates are generally higher than adult literacy rates. This is a reflection of the fact that younger generations are typically more likely to be able to read and write than older generations, except as countries reach universal literacy, as in Central and Eastern Europe, Central Asia, and North America and Western Europe. The spread between the countries with the lowest and highest literacy rates is also smaller for youths than for adults. In South and West Asia, for example, the adult literacy rate is expected to range from 60% in Pakistan to 99% in the Maldives in 2015. By comparison, the youth literacy rate is expected to range from 77% in Pakistan to nearly 100% in the Maldives in the same year. This increase in literacy rates over time can be observed in nearly all countries with data.

Please consult the report published by the UIS for further analysis of adult and youth literacy. The statistical annex of the report contains all national adult and youth literacy rates shown in Figures 1 and 2.

National, regional and global literacy trends, 1985-2015

The UNESCO Institute for Statistics (UIS) has released a new report on literacy (UIS 2013). The report, Adult and Youth Literacy: National, Regional and Global Trends, 1985-2015, contains a comprehensive overview of literacy data for 151 countries and territories from seven regions: Arab States, Central and Eastern Europe, Central Asia, East Asia and the Pacific, Latin America and the Caribbean, North America and Western Europe, South and West Asia, and sub-Saharan Africa. A summary of the most recent literacy rates and estimates of the illiterate population is accompanied by historical data for the period since 1985 and projections to 2015, the target year of Education for All and the Millennium Development Goals.

The table and figure below present adult literacy rates, for the population 25 years and older, at the regional and global level between 1990 and 2015. In spite of persistent illiteracy in some parts of the world - see the article "Adult and youth literacy in 2011" - the adult literacy rate has increased in all regions since 1990. The global adult literacy rate grew from 76% in 1990 to 82% in 2000 and 84% in 2011, the most recent year with data. (In the report, 1990 data refer to the period 1985-1994, 2000 data to the period 1995-2004, and 2011 data to the period 2005-2011.)

Progress at the regional level has varied. In three regions - Arab States, South and West Asia, and sub-Saharan Africa - approximately half of all adults were illiterate in 1990. In the Arab States, the adult literacy rate increased by 22% between 1990 and 2011. In South and West Asia, the adult literacy rate increased by 16% over the same period. In sub-Saharan Africa, progress was much more modest, with an increase in the adult literacy rate of only 6%. East Asia and the Pacific is approaching universal adult literacy, and Central and Eastern Europe and Central Asia were already near universal literacy in 1990. No regionally representative data are available for North America and Western Europe.

The EFA goals, adopted at the World Education Forum in Dakar in 2000, call for a "50% improvement in levels of adult literacy by 2015" (UNESCO 2005). For monitoring, this goal is typically interpreted to mean a reduction of the adult illiteracy rate by 50% between 2000 and 2015. EFA goals were set for countries, not regions, but for the analysis in the UIS report, target values were also calculated at the regional and global levels. At the global level, for example, halving adult illiteracy between 2000 and 2015 implies a target adult literacy rate of 91% for the year 2015.

Adult literacy rates are projected to increase in almost all regions between 2011 and 2015. The exception is Central and Eastern Europe, where projections indicate a small drop in adult literacy. The global adult literacy rate is projected to reach 86% in 2015, meaning that the target literacy rate would be missed by 5%. As the figure below shows, sub-Saharan Africa is projected to be furthest from the 2015 target, with an estimated adult literacy rate of 64%, 15% below the target of 79%. South and West Asia is projected to reach an adult literacy rate of 70% in 2015, 9% below the target for 2015. Central and Eastern Europe, Central Asia, and East Asia and the Pacific are projected to reach or come within one percentage point of the 2015 target.

Adult and youth literacy in 2011

8 September is International Literacy Day, an occasion to reflect on the status of literacy worldwide. Globally, 84% of all adults 15 years and older were able to read and write in 2011, the most recent year for which the UNESCO Institute for Statistics (UIS) has released data (see Table 1). Two regions, Central and Eastern Europe and Central Asia, are near universal literacy, with adult literacy rates of 99% and 100%, respectively. Literacy rates are assumed to be at a similarly high level in North America and Western Europe but data coverage is insufficient for the calculation of a regional average. Literacy rates are also high in East Asia and the Pacific (95%) and in Latin America and the Caribbean (92%). In the remaining regions, adult literacy rates are below the global average: Arab States (77%), South and West Asia (63%), and sub-Saharan Africa (59%).

Male and female adult literacy rates are at nearly the same levels in three regions: Central and Eastern Europe, Central Asia, and Latin America and the Caribbean (see Table 1). In the Arab States, East Asia and the Pacific, South and West Asia, and sub-Saharan Africa, female literacy rates are lower than male literacy rates. The gender parity index (GPI), the ratio of the female over the male literacy rate, shows that the biggest gender gap exists in South and West Asia (GPI 0.70) and in sub-Saharan Africa (GPI 0.74). Globally, the male literacy rate is 89% and the female literacy rate 80%, which yields a GPI of 0.90, far below the range of gender parity with GPI values between 0.97 and 1.03.

National adult literacy rates are displayed in Figure 1. Countries in sub-Saharan Africa and South and West Asia have generally lower literacy rates than countries in other regions. In 11 countries, nearly all in sub-Saharan Africa, fewer than half of all adults are able to read and write: Benin, Burkina Faso, Chad, Ethiopia, Guinea, Haiti, Liberia, Mali, Niger, Senegal, and Sierra Leone.

The UIS estimates that the adult illiterate population was 774 million in 2011 (see Table 2). Three out of four illiterate adults live in only two regions: South and West Asia (407 million) and sub-Saharan Africa (182 million). In all regions, the number of illiterate women is larger than the number of illiterate men. Globally, 493 million or two thirds of the adult illiterate population are female.

The global youth literacy rate, for the population 15 to 24 years of age, was 90% in 2011 (see Table 1). Youth literacy rates are higher than adult literacy rates in all regions, a result of increased levels of school attendance among younger generations. Of the regions with data, four are near universal youth literacy: Central and Eastern Europe (99%), Central Asia (100%), East Asia and the Pacific (99%), and Latin America and the Caribbean (97%). In the Arab States, the youth literacy rate is 90%. In South and West Asia (81%) and sub-Saharan Africa (70%), the youth literacy rate is below the global average.

Literacy rates among the population 15-24 years are not only higher than among the total population 15 years and older, there is also a smaller gap between the literacy rates of young men and women (see Table 1). However, gender disparity in youth literacy is observed in the Arab States (GPI 0.93), South and West Asia (GPI 0.86), and sub-Saharan Africa (GPI 0.84); in these regions, young women are less likely to be able to read and write than young men. At the global level, the male youth literacy rate is 92% and the female youth literacy rate 87%.

National youth literacy rates are displayed in Figure 2. Sub-Saharan Africa stands out as the one region where youth literacy rates are significantly lower than in other regions. Seven countries have youth literacy rates below 50%: Benin, Burkina Faso, Chad, Guinea, Liberia, Mali, and Niger.

Figure 2: Youth literacy rate, 2011

The youth illiterate population, a subset of the adult illiterate population, was estimated at 123 million in 2011 (see Table 2). Illiterate youth are concentrated in South and West Asia and sub-Saharan Africa; 89% of the global population of illiterate youth live in these two regions. Whereas women are the majority of illiterate adults in all regions, there is no such clear pattern among illiterate youth. In two regions, Central Asia and Latin America and the Caribbean, young men are more likely to lack basic reading and writing skills than young women. Even so, 61% of the global number of illiterate youth are female.

More detailed statistics and analysis are available from the the UNESCO Institute for Statistics, including a page with an interactive world map with adult and youth literacy rates, a fact sheet on adult and youth literacy, an infographic for International Literacy Day 2013, and a report on national, regional and global trends in adult and youth literacy between 1985 and 2015.

Adult and youth literacy in 2010

The UNESCO Institute for Statistics (UIS) released new literacy data in April 2012, with updated estimates of adult and youth literacy. In 2010, the latest year with data, 84% of the global population 15 years and older were estimated to be able to read and write (see Table 1). At the regional level, literacy rates are highest in Central Asia, Central and Eastern Europe, East Asia and the Pacific, and Latin America and the Caribbean. In these regions at least 9 out of 10 adults are literate. Literacy rates can be assumed to be as high in North America and Western Europe but not enough countries in that region collect literacy data to allow the calculation of a regional average. By contrast, adult literacy rates are significantly lower in the Arab States (75%), and in South and West Asia and sub-Saharan Africa (63% in both regions). Women are considerably less likely to be literate than men in the Arab States, East Asia and the Pacific, South and West Asia, and sub-Saharan Africa. Globally, the female adult literacy rate was estimated to be 80% in 2010, compared to a literacy rate of 89% for men. As a consequence, nearly two thirds (497 million) of the adult illiterate population in 2010 (775 million) were women.

Table 1: Adult and youth literacy rate, 2010

The disparities between regions with high and low literacy rates are readily apparent from the map in Figure 1, which displays the average literacy rate in the seven Education for All (EFA) regions with data listed in Table 1. For a description of the regional groupings, please refer to a past article about the EFA regions on this website.

Figure 1: Regional adult literacy rate, 2010

Youth literacy rates, for the population 15 to 24 years of age, are higher than adult literacy rates in all regions as a result of improved access to education among younger generations. Globally, 90% of all youth are able to read and write. Central Asia, Central and Eastern Europe, East Asia and the Pacific, and Latin America and the Caribbean have reached or are approaching universal literacy among their young population. The same can be assumed for North America and Western Europe, but no regional average is available from the UIS (see Table 1 and Figure 2). The disparity in literacy rates between men and women is generally smaller among the population 15 to 24 years than among the population 15 years and older. Yet, in the Arab States, South and West Asia, and sub-Saharan Africa, young women remain less likely to be able to read and write than young men. The global youth literacy rate in 2010 was 92% for men and 87% for women.

The regional averages can conceal large differences between countries within a region. This is particularly true for the adult literacy rate in the Arab States, South and West Asia, and sub-Saharan Africa (see Figure 3). In sub-Saharan Africa, for example, the adult literacy rate is below 30% in Burkina Faso and Niger - the countries with the least literate population worldwide - and above 90% in Equatorial Guinea, Seychelles, and Zimbabwe.

Figure 3: Adult literacy rate, 2010

Disparities between countries within a region can also be observed for the youth literacy rate, but to a lesser degree than for the adult literacy rate (see Figure 4). Similar to the adult literacy rate, the greatest disparities exist in sub-Saharan Africa, where youth literacy rates range from 37% in Niger to 99% in the Seychelles and Zimbabwe.

To make it easier to explore its literacy data, the UNESCO Institute for Statistics has created an interactive visualization that combines a map showing adult and youth literacy rates, a graph with literacy rates by sex, and a scatter plot with the correlation between GDP per capita and literacy. A screenshot of the visualization is shown in Figure 5. The full visualization is available on the website of the UIS. Literacy data are also contained in the recently published World Atlas of Gender Equality in Education by UNESCO.

World Atlas of Gender Equality in Education

Cover of the UNESCO gender atlas

UNESCO and the UNESCO Institute for Statistics (UIS) have published a new World Atlas of Gender Equality in Education that illustrates the participation of girls and boys in pre-primary, primary, secondary, and tertiary education. The data show that there has been significant progress towards gender parity since the 1970s. Two thirds of all countries have reached gender parity in primary education but at the secondary level of education girls are still lagging behind. In some countries, girls have the advantage with regard to access to and completion of education. At the tertiary level, female students outnumber male students in many high-income countries.

The atlas is divided into eight chapters that contain a total of 28 maps and close to 100 charts and tables:

  1. Increased worldwide demand for quality schooling
  2. Girls’ right to education
  3. Enrolment and gender trends: primary education
  4. Enrolment and gender trends: secondary education
  5. Enrolment and gender trends: tertiary education
  6. Trends in school-life expectancy
  7. Gender trends: adult and youth literacy
  8. How policies affect gender equality in education

An excerpt from Chapter 7 on literacy is shown below. The map (please click the image for a larger view) visualizes adult literacy rates from the database of the UNESCO Institute for Statistics. Among countries with data, literacy rates are lowest in sub-Saharan Africa and South Asia. The highest adult literacy rates are observed in Eastern Europe and Central Asia. For many developed countries, the adult literacy rate is unknown because these countries have achieved universal primary education and no longer report data on the traditional literate-illiterate dichotomy, focusing instead on the more narrowly defined concept of functional literacy.

The atlas is available in English, French and Spanish. In addition, UNESCO and UIS plan to launch an online e-atlas with interactive maps.

Adult and youth literacy in 2009

8 September was International Literacy Day. On this occasion, the UNESCO Institute for Statistics (UIS) released a fact sheet with estimates of adult and youth literacy in 2009, the most recent year with data.

The global adult literacy rate, for the population 15 years and older, was 83.7% in 2009, compared to 83.4% in 2008. The adult illiterate population fell from 796.2 million in 2008 to 793.1 million in 2009. 64.1% of the adult illiterate population were women. Adult literacy rates are lowest in sub-Saharan African and in South and West Asia (see Figure 1). In 11 countries, less than half of the adult population were able to read and write: Benin, Burkina Faso, Chad, Ethiopia, Gambia, Guinea, Haiti, Mali, Niger, Senegal and Sierra Leone.

Youth literacy rates - for the population 15 to 24 years - are generally higher than adult literacy rates, due to increased school attendance rates among younger generations. The global youth literacy rate was 89.3% in 2009, compared to 89.0% in 2008. The youth illiterate population fell from 130.6 million in 2008 to 127.3 million in 2009. Youth literacy rates are lowest in sub-Saharan Africa (see Figure 2) and the five countries worldwide with youth literacy rates below 50% are from this region: Burkina Faso, Chad, Ethiopia, Mali and Niger.

EFA Global Monitoring Report 2011

Cover of the EFA Global Monitoring Report 2011The Education for All Global Monitoring Report 2011 was released by UNESCO on 1 March 2011. This year's edition of this annual report has the title The hidden crisis: Armed conflict and education. The report documents the impact of violent conflict on education and the long-lasting negative effects on educational attainment and literacy.

Today, 28 million or over 40 percent of all children out of school (67 million worldwide) live in countries affected by conflict, although these countries are home to only 116 million or 18 percent of the global population of primary school age (653 million) (see Figure 1). (Only out-of-school children in low and lower-middle income conflict-affected countries were counted to arrive at the total of 28 million. In addition, for large countries like India, Indonesia, Nigeria and Pakistan, only children living in conflict-affected areas were included in the 28 million children affected by conflict.) In conflict areas, the out-of-school rate is around 24 percent, compared to 7 percent in other parts of the world. Children affected by armed conflict are thus more than three times as likely to be out of school as other children.

Conflict-affected countries also have some of the lowest levels of literacy. In these countries, only 79 percent of youth between 15 and 24 years and 69 percent of adults are literate, compared to 93 percent of youth and 85 percent of adults in other countries.

War does not only destroy lives and schools, it also diverts resources from education to military spending. The Global Monitoring Report documents how lack of access to education or exposure to the wrong kind of education can contribute to persistent inequality, prejudice and renewed armed conflict, a vicious cycle that is difficult to break.

Lastly, the Global Monitoring Report 2011 examines the role of development assistance in conflict-affected countries and argues for increased and more effective aid for the education sector.

Trends in adult literacy, 1990-2008

8 September is International Literacy Day, which was first celebrated in 1966. New estimates of adult and youth literacy by the UNESCO Institute for Statistics (UIS) show that the percentage of literate persons continues to grow worldwide. Even so, in 2008, 796 million adults aged 15 years or older - 17% of all adults worldwide - still lacked basic reading and writing skills and 64% of them were women (see UIS fact sheet on adult and youth literacy). By comparison, 24% of all adults were illiterate in 1990.

Figure 1 displays how the adult literacy rate and the associated gender parity index (GPI) have evolved between 1990 and 2008 for the 10 Millennium Development Goal regions and for the world as a whole. The gender parity index is the ratio of the female over the male literacy rate. For example, the female and male literacy rate in 2008 - 78.9% and 88.2%, respectively - yield a GPI of 0.9 (see Table 1). A GPI between 0.97 and 1.03 is usually considered gender parity. At GPI values below 1, women are disadvantaged and at GPI values above 1, men are disadvantaged. If a country or region reaches universal literacy, with male and female literacy rates of 100%, the GPI must be 1 by definition. This can be seen in the developed regions and in the countries of the Commonwealth of Independent States (CIS), both of which are near universal literacy with a GPI of 1.

At the global level, both the adult literacy rate and gender parity improved over the past 20 years. The literacy rate grew from 76% in 1990 to 83% in 2008 and the GPI from 0.84 to 0.90 (see Table 1). Progress was especially strong in Northern Africa, where the adult literacy rate increased by 20%, and in Eastern and Southern Asia, which saw an increase of 15%. In Northern Africa and Southern Asia less than half of all adults were literate in 1990, less than in any other region. In 2008, the lowest literacy rates were observed in Southern Asia and sub-Saharan Africa, with 62% and 63%, respectively. However, even sub-Saharan Africa managed to increase the share of adults with basic reading and writing skills by 9% between 1990 and 2008. In the remaining regions, the increase in the adult literacy rate over the past two decades was as follows: Western Asia 11%; South-Eastern Asia, and Latin America and the Caribbean 7%; Oceania 4%; CIS 1%; and the developed regions 0.3%. The rate of increase in the developed regions and in the CIS countries was neglible because both regions had already reached near-universal adult literacy in 1990. Literacy rates are also high in Eastern Asia, South-Eastern Asia, and Latin America and the Caribbean; in all three regions more than 9 out of 10 adults are able to read and write.

Gender parity also improved in all MDG regions, with Northern Africa again showing the biggest increase, from 0.57 in 1990 to 0.76 in 2008, followed by Eastern Asia and Southern Asia, where the GPI increased by 0.14 over the same period. In spite of this increase, Southern Asia continues to exhibit relatively high gender disparity in adult literacy, with a GPI of 0.70. The UIS reports similar disparities for sub-Saharan Africa (0.75) and Northern Africa (0.76). In the other regions the GPI for adult literacy was as follows in 2008: Western Asia 0.84, Oceania 0.89, Eastern Asia 0.94, South-Eastern Asia 0.95, and CIS and the developed regions 1.00.

Adult literacy in 2007

The release of new literacy data by the UNESCO Institute for Statistics (UIS) in May 2008 provides an opportunity to update an article on adult literacy rates that was published on this site in July 2007. The adult literacy rate is the share of literate persons in the population aged 15 years and older. Compared to the previous analysis, literacy data for more countries and for more recent years is available. An article on literacy data from the UIS provides additional information on the latest UIS database.

Before the update of May, the UIS database contained adult literacy rates for 136 countries and territories. For 10 countries, the most recent data was from 2005, for 30 countries from 2004, and for 5 countries from 2003. The remaining countries had data from 2002 or earlier years.

The UIS Data Centre now offers the adult literacy rate for 145 countries and territories. For 115 countries, data from 2007 is available. The map below displays the adult literacy rate for all countries with data.

The unweighted mean of the adult literacy rate is 81.2 percent. In 71 countries - including most of Eastern Europe, East and Southeast Asia, and Latin America - 90 percent or more of the adult population can read and write. The highest adult literacy rate, 99.8 percent, is reported for Cuba, Estonia and Latvia. Most countries without data are in the group of industrialized countries, where literacy rates are also likely to be above 90 percent. In 23 countries, the adult literacy rate is between 80 and 90 percent.

At the other extreme are eight countries with literacy rates below 40 percent: Mali (23.3), Chad (25.7), Afghanistan (28.0), Burkina Faso (28.7), Guinea (29.5), Niger (30.4), Ethiopia (35.9), and Sierra Leone (38.1). Another 16 countries have literacy rates between 40 and 60 percent: Benin (40.5), Senegal (42.6), Mozambique (44.4), Central African Republic (48.6), Cote d'Ivoire (48.7), Togo (53.2), Bangladesh (53.5), Pakistan (54.9), Liberia (55.5), Morocco (55.6), Bhutan (55.6), Mauritania (55.8), Nepal (56.5), Papua New Guinea (57.8), Yemen (58.9), and Burundi (59.3). Almost all of these countries are in Sub-Saharan Africa and South Asia.

Finally, the world's two largest countries in terms of population have very different literacy rates. In China, the adult literacy rate is 93.3 percent. In India, only 66 percent of the adult population can read and write.

The complete dataset with adult and youth literacy rates is available at the UIS Data Centre.

Literacy data from the UNESCO Institute for Statistics

In May 2008, the UNESCO Institute for Statistics (UIS) added new literacy data for many countries to its database at the UIS Data Centre. In total, 208 countries and territories are covered by the database. The adult literacy rate - the share of the population aged 15 years and above that can read and write - is available for 145 countries. For 115 countries, the most recent literacy data is from 2007. Historical data is also provided, going back as far as 1975, to allow the analysis of national trends in literacy.

The previous UIS database from 2007 listed the adult literacy rates for 136 countries and territories for years between 1985 and 2005. For 10 countries, the most recent data was from 2005, for 30 countries from 2004, and for 5 countries from 2003.

The graph below describes the availability of data on adult literacy in the UIS database as of late May 2008.
  • The blue bars indicate the number of countries with data on adult literacy per year between 1975 and 2007. For each country, the adult literacy rate may be available in more than one year. The number of countries with data from a particular year is shown at the bottom of the bars, along the horizontal axis. For example, 115 countries have literacy data from 2007 and 36 countries have data from 2000.
  • The brown bars show the number of countries with adult literacy rates from the current year or the previous 4 years. For example, the bar for the year 2007 indicates that 117 countries have literacy data from any year between 2003 and 2007.
  • The beige bars show the cumulative number of countries with literacy data from any year since 1975. For example, in 2007, the adult literacy rate is available for a total of 145 countries and territories. The difference between the beige and brown bars in 2007 is the number of countries with the most recent literacy data from a year before 2003. The difference between the beige and blue bars in 2007 is the number of countries with the most recent data from a year before 2007.

Adult literacy in sub-Saharan Africa

Literacy data published by the UNESCO Institute for Statistics (UIS) in 2007 shows that the lowest adult literacy rates are observed in Africa and South Asia. In some countries, fewer than three out of ten adults can read and write. UIS provides national literacy data for two age groups: youths aged 15 to 24 years, and adults aged 15 years and older. A more detailed analysis of literacy is possible with data from household surveys.

Most Demographic and Health Surveys (DHS) collect data on literacy for persons between 15 and 49 years. For male household members, literacy data is sometimes collected up to an age of 54, 59, or 64 years. To assess the degree of literacy, respondents to the survey are asked to read a card with a simple sentence. If a respondent can read the whole sentence, he or she is counted as literate, in accordance with UNESCO's definition of literacy as "the ability to read and write, with understanding, a short simple sentence about one’s everyday life". Recent Multiple Indicator Cluster Surveys (MICS) by UNICEF collect data on literacy with the same method, but only for female household members between 15 and 49 years. MICS surveys are therefore not covered by the analysis that follows.

This article examines data from eight DHS surveys that were carried out in sub-Saharan Africa between 2003 and 2006. The survey data is from Benin (2006), Burkina Faso (2003), Cameroon (2004), Lesotho (2004-05), Niger (2006), Nigeria (2003), Uganda (2006), and Zimbabwe (2005-06). The data can be used to calculate overall literacy rates and also to examine trends over time by comparing literacy rates in different age groups.

The following table lists literacy rates for the male, female, and total population between 15 and 49 years of age. Zimbabwe (85%) and Lesotho (79%) are the countries with the highest literacy rates, followed by Cameroon (63%), Uganda (58%), and Nigeria (55%). In Benin (33%), Burkina Faso (18%), and Niger (13%), adult literacy rates are much lower. In seven of the eight countries there is a large difference between male and female literacy rates. In Benin, Burkina Faso, Cameroon, Niger, Nigeria, and Uganda, more men than women are literate, with a gender gap ranging from 12% to 26%. In Lesotho, the literacy rate of women is 21% greater than the literacy rate of men. In Zimbabwe, the difference between the male and female literacy rate is only 6%.

Adult literacy rate (%), population 15-49 years
Country
 Male Female Total
Benin 45.1 21.8 32.6
Burkina Faso 24.3 11.9 17.6
Cameroon 70.6 54.8 62.5
Lesotho 68.8 90.1 79.4
Niger 20.9 7.5 13.2
Nigeria 68.4 42.8 54.9
Uganda 68.6 48.9 58.4
Zimbabwe 87.9 81.5 84.5

For the graph below, the survey respondents were divided into five-year age groups. In all countries, literacy rates among the younger population are higher than among the older population. The literacy rate of the youngest group, 15 to 19 years, can be interpreted as a measure of the coverage and quality of the primary school system during the 1990s, when the members of this age group were of primary school age.

In Burkina Faso, Cameroon, Lesotho, Niger, and Uganda, the difference between the literacy rates of 15- to 19-year-olds and 45- to 49-year-olds ranges from 13% to 18%. These numbers indicate a relatively modest expansion of the education system between the 1960s, when the older age group was of primary school age, and the 1990s. In contrast, in Benin, Nigeria, and Zimbabwe, the difference between the literacy rates of 15- to 19-year-olds and 45- to 49-year-olds ranges from 27% to 32%. These three countries were thus more successful in their efforts to increase the number of literate citizens than the other five countries.

In Burkina Faso and Niger, less than one quarter of the population between 15 and 19 years can read and write. However, the case of Benin shows that a large increase in literacy can be achieved within only ten years. In Benin, only 24% of 25- to 29-year-olds are literate but among 15- to 19-years-olds the literacy rate has grown to 53%.
