National wealth and school enrollment

The first and second goal of the Millennium Development Goals are the eradication of extreme poverty and hunger and the achievement of universal primary education. In previous posts I presented evidence on the connection between poverty and education in India and the United States. At the global level, this link is also evident. Middle and high income countries typically have higher levels of school enrollment than low income countries.

This relationship can be demonstrated by plotting school net enrollment ratios (NER) against gross domestic product (GDP) per capita as a measure of national wealth. The graphs below present the primary and secondary school NER in 2002/03 (the latest year with data) in relation to GDP per capita in 2002. School enrollment figures are from the Global Education Digest 2005 by UNESCO and the GDP per capita from the World Development Indicators 2005 by the World Bank. The GDP data was adjusted with purchasing power parities (PPP) to take the price levels in different countries into account. In addition, the GDP per capita is plotted on a logarithmic scale so that the relationship with NER can be seen more easily.

The first graph makes clear that low income countries have significantly lower levels of primary school enrollment. Most countries with a GDP per capita of $2,500 or less have net enrollment ratios below 80%. Almost all countries above this level of GDP have NER values of more than 80%.

The link between national wealth and school enrollment is even more obvious at the secondary level of education. Virtually all countries with a secondary school NER below 60% have a GDP per capita of less than $10,000. In contrast, all countries with a per capita income of more than $15,000 have NER levels near or above 80%.

Poverty and educational attainment in the United States, part 2

Poverty and education are closely linked. In India, for example, children from the poorest households are least likely to attend primary school. Such a link between poverty and education also exists in industrialized countries. In the United States, the states with the highest poverty rates are also those with the lowest share of high school graduates. The graph below plots the percent of the population living below the poverty level against the percent of the population above 25 years of age without complete high school education. The data is from the 2004 American Community Survey and all states are marked with their U.S. postal abbreviation.

The regression line emphasizes the close link between poverty and lack of education in the United States. Mississippi has the poorest and least educated population, with 22 percent living below the poverty level and 23 percent not having graduated from high school. Other states with a low share of high school graduates and high poverty rates are Alabama, Arkansas, Kentucky, Louisiana, New Mexico, Texas, and West Virginia. In contrast, Alaska, Connecticut, Minnesota, and New Hampshire have the least poor and most educated population in the United States. In the country as a whole, 13 percent of the population live below the poverty level and 16 percent did not graduate from high school.

Poverty and educational attainment in the United States

On August 29, 2005, hurricane Katrina, possibly the deadliest storm in U.S. history, caused extensive damage in the southeastern United States. The victims of Katrina tended to be black, poor and less educated and many did not have the means to leave the area before the storm arrived.

Alabama, Louisiana and Mississippi, the states that were particularly hard hit, are among the poorest in the nation, according to data from the 2004 American Community Survey by the U.S. Census Bureau. In Mississippi, 21.6% of the population lived below the poverty line, more than in any other U.S. state. Louisiana was the second poorest state, with 19.4% of the population living below the poverty line. Alabama was the ninth poorest of the 50 states, with 16.1% below the poverty line. New Orleans, the city with the highest number of storm victims, had a poverty rate of 23.2%. In comparison, 13.1% of the entire U.S. population lived below the poverty line in 2004. In terms of education, the three states affected most by the hurricane also rank near the bottom of the 50 U.S. states, as the graph below shows.

Percent of population 25 years and over who graduated from high school, United States 2004
Bar chart with percent of population who completed high school, United States 2004
Data source: 2004 American Community Survey.

The 2004 American Community Survey found that 83.9% of the U.S. population aged 25 years and over graduated from high school, which means that they have at least 12 years of education. In the graph above, the states are ranked by the share of the population who completed high school. Mississippi had the lowest percentage of high school graduates, 77.3%. Alabama with 79.5% and Louisiana with 79.9% rank fifth and sixth in terms of the lowest share of high school graduates.

The victims of hurricane Katrina are mostly from the margins of U.S. society, poor, with little education and limited economic opportunities. Local, state and national government agencies have the responsibility to assist those in need but there has been widespread criticism of the government's slow response to the disaster. Many survivors have lost their homes and other belongings and are unable to provide for themselves. They will depend on help from the government and charitable organizations like the Red Cross for many months and years to come.

Primary school attendance in India

Today I will begin a series of posts that take a closer look at gender disparity in school attendance. Goal 3 of the Millennium Development Goals calls for the promotion of gender equality and the empowerment of women. The targets listed under this goal include the elimination of gender disparity in primary and secondary education, preferably by 2005, and at all levels of education no later than 2015.

Education statistics published by UNESCO are mostly based on administrative records of enrollment. Data from household surveys are an alternative source of statistics on school attendance. Because household surveys collect data on various characteristics of children and the households they live in it is possible to analyze gender disparity in more detail than with national enrollment data on primary or secondary education.

With household survey data a child is counted as being in school if one of the following two conditions is met:
  1. The child attended school during the week preceding the survey.
  2. The child was in school anytime during the year preceding the survey. This condition is added to account for children who were not in school because they were ill, because they were on vacation, or for other reasons.
In India, one of the most recent surveys is a Multiple Indicator Cluster Survey (MICS) that was conducted in 2000. Overall, 72.1% of all children of primary school age (6-10 years) were attending primary school according to the data from the India MICS (see also the graph in a previous post). The graph below presents the primary school NAR for boys and girls disaggregated by the area of residence and by household wealth.

Data source: India 2000 MICS.

In the country as a whole, more boys than girls go to primary school. The NAR of boys is 6.6% higher than the NAR of girls (see the table below). This gender disparity at the country level is clearly driven by the patterns of school attendance in rural areas and in poor households. In urban areas and among the richest 20% of the population, boys' and girls' attendance rates are virtually identical. Rural families and those from the poorest 20% of the population, on the other hand, are likely to send only boys to school when they cannot afford education for all their children. To reach the Millennium Development Goal of gender parity, policy makers have to focus their efforts on rural India and on households that suffer from poverty.

Education data from household surveys

Education statistics published by the UNESCO Institute for Statistics rely on two sources of data: (a) administrative records of enrollment that are provided by national governments and (b) population statistics from the United Nations Population Division. For example, the primary school net enrollment rate is calculated as follows:
  • Primary school NER = children of primary school age enrolled in primary school / total population of primary school age
The numerator uses national enrollment data and the denominator population data from the UN Population Division. This combination of data from two different sources can lead to errors in the calculation of indicators like the NER. Estimates by the UN Population Division may not match the actual population figures in a country. Local schools, whose records are aggregated at the national level, may misstate enrollment to obtain financing and governments may do the same to meet objectives like the Millennium Development Goals. A further limitation of education statistics based on administrative records is that they provide little information about the characteristics of students beyond age and sex. In spite of these concerns, the data published by UNESCO remains the most comprehensive collection of global education statistics.

Household surveys are an alternative source of data on education. Because survey data is collected at the household level, it is possible to capture a large amount of additional information on children and the households and communities they live in. In contrast to records of enrollment, household surveys also provide data on children out of school that can be analyzed to guide policies aimed at increasing school enrollment rates.

Estimates derived from surveys use a single source of data, which minimizes problems that arise from the combination of data from different sources. However, the estimates are affected by two other types of errors: sampling errors and nonsampling errors. Sampling errors arise because surveys cover only a part of the population and estimates are therefore not identical to those that would be obtained by surveying the entire population of a country. Nonsampling errors are the result of mistakes during data collection and data processing, for example incorrect responses by survey respondents and mistakes during data entry. Sampling errors can be minimized by selecting a sufficiently large sample and nonsampling errors can be minimized through training of survey staff.

Two household survey programs that focus on developing countries are the Demographic and Health Surveys (DHS) and the Multiple Indicator Cluster Surveys (MICS). The DHS were initiated by the U.S. Agency for International Development (USAID) in the 1980s to provide data on population and health trends. The MICS program was developed by UNICEF in the 1990s to monitor the situation of women and children.

Both the DHS and the MICS collect data on school attendance. As an example I show estimates for the primary school net attendance rate (NAR) from the 2000 MICS in India. The primary school NAR is calculated as follows:
  • Primary school NAR = number of children of primary school age that are attending primary school / number of children of primary school age
Similar to the NER, the maximum value of the NAR is 100%. In the India MICS, 72.1% of all children of primary school age (6-10 years) were found to be in primary school. Attendance rates were higher among boys than girls (75.3% vs. 68.7%). NER data from UNESCO limits the analysis to a breakdown by sex but with survey data we can also analyze other disparities. In India, for example, urban children (NAR 76.8%) are more likely to attend primary school than rural children (NAR 70.7%). Household wealth is also an important determinant of school attendance. Among the poorest 20% of all households, only 64.0% of children attend primary school, compared to 81.9% of children from the richest 20% of all households.

In the coming weeks I will present more education data from household surveys. By providing detailed information on the determinants of school attendance at the household level, surveys are an important tool for policy makers and for researchers and organizations that work in the area of education.
