IPUMS-DHS Unlocks Research Possibilities with New Contextual Data

Have you ever wondered if high-levels of precipitation affect birthweights and infant and child survival? Is increased use of insecticide-treated bed nets associated with lower incidence of malaria? Do children in households near battle zones or other violent contexts have higher levels of child malnutrition? Do some staple crop regimes promote better health outcomes than others?

Now with IPUMS-DHS, you can easily study these questions and others on how environmental and social contexts affect human health and behavior.

Using GPS coordinates, we’ve linked contextual variables drawn from many data sources directly to individual DHS survey respondent records. All context variables describe the features of a small geographic area (5-10 kilometers) surrounding each DHS survey cluster location.

New variables include:

Environmental
Variables
Agricultural
Variables
Social
Variables
  • Soil type
  • Ecoregion
  • Level of vegetation
  • Precipitation
  • Proportion of land area used for agriculture or pastureland
  • Total harvested area and yield for 17 major crops
  • Dominant livelihood
  • Population density
  • Counts of violent episodes
  • Incidence of malaria

Keep checking back! Over the next year, IPUMS-DHS will still be adding more contextual variables, including summary statistics calculated from large census-based samples.

Plan a new research project linking individual characteristics and outcomes with the surrounding context, and let us know about it. We’re always eager to hear how people are using IPUMS-DHS!

IPUMS-DHS is a system that makes it easy to find and review the thousands of DHS survey variables and to download a single fully-harmonized data file with precisely the variables and samples that interest you. The system currently includes variables from all DHS survey samples taken in India and 22 African countries; more samples are constantly being added.

For DHS survey samples with GPS cluster data that are not yet in IPUMS-DHS, the contextual variables are available in linkable CSV files.

  • The Demographic and Health Surveys (DHS) Program has collected, analyzed, and disseminated accurate and representative data on population, health, HIV, and nutrition through more than 400 surveys in over 90 countries. The DHS Program is funded by the U.S. Agency for International Development (USAID). Contributions from other donors, as well as funds from participating countries, also support surveys. The project is implemented by ICF.

Anthropometry measurement (height and weight) is a core component of DHS surveys that is used to generate indicators on nutritional status. The Biomarker Questionnaire now includes questions on clothing and hairstyle interference on measurements for both women and children for improved interpretation.
