- Primary school NER = children of primary school age enrolled in primary school / total population of primary school age
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
Primary school net attendance rate, India 2000
Data source: India 2000 MICS.
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.
