The DHS Fellows Program Goes Virtual in 2022

The application for the 2022 DHS Fellows Program is now open

The DHS Fellows Program builds the long-term institutional capacity of universities in DHS Program countries to train students and faculty to analyze DHS data. Since 2011, the DHS Fellows Program has trained more than 150 researchers from over 40 universities in 25 countries in Africa, Asia, and the Middle East. Typically, Fellows attend two separate in-person workshops, prepare publication-quality research papers in teams using DHS datasets, and implement capacity strengthening activities at their home universities.

The 2022 DHS Fellows Program will be conducted virtually and in English. Because the DHS Fellows Program will be virtual, this year’s call for applications is open to countries that have not been included in the DHS Fellows Program previously. Applications are accepted from university faculty members at universities in Angola, Benin, Burundi, Gambia, Liberia, Mali, Sierra Leone, South Africa, Maldives, Papua New Guinea, Timor-Leste, Guatemala, Haiti, Armenia, and Tajikistan. Teams of three members from the same university who teach and/or conduct research in demography, public health, economics, sociology, or other social sciences are encouraged to apply.

Read about how the 2020 DHS Fellows Program was impacted by the COVID-19 pandemic and adapted to be delivered virtually.

Visit The DHS Program Fellows page to see all DHS Fellows’ working papers and publications in peer-reviewed journals. The deadline to submit applications is November 21, 2021.

New Resources Provide Updated Guidance on Biomarker Collection in DHS-8

The DHS Program is pleased to announce the availability of the Biomarker Manual: Training Program for Measuring and Testing for Biomarkers and the DHS Height Standardization Tool on The DHS Program website.

The Biomarker Manual aligns with DHS-8 standard materials and policies representing the most up-to-date procedures. Standard measures in DHS surveys include height/length, weight, and hemoglobin. Anthropometric data are collected for children age 0-59 months, women age 15-49, and men age 15-49, 15-54, or 15-59 depending on the survey. These data are used to estimate malnutrition in children, body mass index (BMI) in adults, and BMI-for-age in adolescents. Hemoglobin measurement provides anemia prevalence estimates for children age 6-59 months along with women and men.

The Biomarker Manual is a critical resource used by DHS Program biomarker specialists and consultants to train biomarker technicians and supervisors on all aspects of collecting high-quality biomarker data. The Biomarker Manual can serve as a tool for others conducting surveys similar to DHS surveys. The manual includes procedures for:

  • Completing The DHS Program Biomarker Questionnaire and related documentation
  • Anthropometric measurement
  • Capillary blood collection
  • Hemoglobin measurement
  • Biohazardous waste management and disposal
Example of an informational pamphlet in the Biomarker Manual

The Biomarker Manual also includes examples of materials to aid in data collection – informational pamphlets provided to households, referral forms provided for cases of severe acute malnutrition and severe anemia, forms used during training on anthropometry (e.g., standardization exercises), and forms for monitoring equipment during fieldwork (daily maintenance logs).

The DHS Height Standardization Tool is used during the anthropometry standardization exercise to record trainees’ height or length measurements and to calculate trainees’ accuracy and precision. The results of the calculations are illustrated visually for each trainee and compared to the pass/fail cutoffs for accuracy and precision. The tool is a useful resource for anyone collecting anthropometry data in surveys or research as it helps to identify trainees who may need further training and re-standardization before data collection. 

Many DHS surveys collect additional biomarkers in addition to the standard biomarkers mentioned above, e.g., malaria rapid diagnostic testing (RDT), dried blood spot (DBS) preparation for lab-based testing for a variety of infections or conditions, blood pressure measurement, and micronutrient biomarkers. The resources in the new Biomarker Manual can be adapted to accommodate the collection of these other biomarkers.

Family Planning Data Highlighted in First DHS Program Tableau Dashboard

Did you know that almost half of sexually active unmarried women in Nigeria age 15-49 have an unmet need for family planning, compared with only 19% of married women? Or that unmet need among sexually active unmarried women is lowest in Peru, at only 6%? These are the types of patterns and trends that jump off the screen in The DHS Program’s new family planning Tableau dashboard.

The DHS Program’s first Tableau dashboard visualizes 5 key family planning indicators in 58 countries. Users can explore global patterns and trends or deep dive into data from a single country. 

The first view presents 5 family planning indicators for 3 groups of women (married women, sexually active unmarried women, and all women). Users can see at a glance how these indicators compare across these 3 groups of women, by background characteristics, and over time.

The “SDG visuals” option visualizes the more complex “demand satisfied by modern methods” indicator.

The “deep dive” presents the individual country data by 5 background characteristics (residence, education, age, wealth quintile, and subnational region).

In the global map view, users can see the range of any selected indicator across 58 recent DHS Program countries.

If you are brand new to Tableau, have no fear. Just click on the “?” icon and basic instructions will overlay your view. 

Already a Tableau expert? Try visualizing DHS Program indicator data through The DHS Program’s Application Programming Interface (API) and look for guidance on connecting to The DHS Program’s API through Tableau coming soon.


Mapping Unrealized Fertility in Sub-Saharan Africa

Many women in DHS Program countries have fewer children than they desire. Our newest StoryMap explores unrealized fertility in sub-Saharan Africa, based on the recently published analysis Comparing Ideal and Completed Family Size: A Focus on Women in Low- and Middle-income Countries with Unrealized Fertility. Unrealized fertility is most common among women in Western and Central Africa where about 60% of women age 40-49 report that they had fewer children than they would have liked.

The StoryMap and paper also explore sex preference, ideal family size, and subnational variation in unrealized fertility.

World Population Day 2021

July 11th is World Population Day. The Household Questionnaire collects information on all members of and visitors to households selected to participate in Demographic and Health Surveys. Basic information including age, sex, marital status, education, and relationship to the head of the household is collected for everyone who stayed in the selected households the night before the interview. Some of this information is visualized in a population pyramid, a great visualization of a country’s distribution of age groups by sex. The population pyramid is typically found in chapter 2 of Demographic and Health Survey Final Reports. Demographers can identify population trends based on a population pyramid’s shape and make predictions about that country’s population in the future.

Test your knowledge of demography, fertility, and population pyramids by taking The DHS Program’s #PopPyramid Quiz featuring population pyramids from recently published Demographic and Health Surveys (DHS). Hint: Use STATcompiler.com to find the answers.

IPUMS Announces Winners of the 2020 Global Health Research Awards

Every year, hundreds of papers are published using DHS Program data. Datasets for individual DHS surveys are available for download from The DHS Program website by completing a simple registration form. Researchers and students can also access the IPUMS DHS data collection to facilitate comparative analysis of DHS Program data. Harmonized across time and space, IPUMS DHS features consistently named and coded variables for 32 African countries and 9 Asian countries, with more datasets constantly being added.

The IPUMS DHS team recently announced the winners of this year’s IPUMS Global Health paper awards, which highlight some of the most exciting research to take advantage of the IPUMS DHS integrated datasets. These papers were selected from a highly competitive field that included nearly 50 studies released in 2020.

The Best IPUMS Global Health Publication Award goes to Zinguang Fan (Department of Sociology, Peking University, Beijing, China) and Maria Vignan Loria (Department of Sociology, University of Washington, Seattle, Washington, USA) for their Demographic Research article, “Intimate Partner Violence and Contraceptive Use in Developing Countries: How Does the Relationship Depend on Context?

Fan and Loria resolve a puzzle in prior research on intimate partner violence (IPV): Why is the relationship between IPV and contraceptive use negative in some countries and positive in others? Using 30 IPUMS DHS samples from 17 countries, the authors demonstrate that the relationship between IPV and family planning is modified by macro contextual factors, including legal prohibitions and national levels of female empowerment. This study stands out not just for answering an important social science question but also in its creative use of the broad range of information collected in DHS Program surveys, including variables on contraceptive use and type, family size preferences, husband-wife disagreement on fertility goals, various indicators of women’s status (e.g., education, employment, decision-making), and domestic violence. In addition, the authors draw on IPUMS DHS variables to determine the direction of causality: from the experience of IPV to increased contraceptive use, rather than from contraceptive use to increased incidence of IPV.

The Best Student Paper Award goes to Siyu Heng (Graduate Group in Applied Mathematics and Computational Science, University of Pennsylvania, Philadelphia, Pennsylvania, USA) and his collaborators Wendy P. O’Meara, Ryan A. Simmons, and Dylan A. Small for their paper, “Relationship between Changing Malaria Burden and Low Birth Weight in sub-Saharan Africa.

This study leverages geographic heterogeneity to determine the effect of reduced malaria burden on low-birth-weight rates across communities in 19 sub-Saharan African countries. Low birth weight is a serious health risk associated with cognitive and physical difficulties among children. This careful and cleverly designed study analyzes IPUMS DHS data from countries with at least two surveys and GPS data on survey cluster locations.  After using optimal matching to pair DHS Program survey clusters separated in time, the authors use a difference-in-difference approach to compare the incidence of low birth weight in areas that did and did not experience malaria decline. Results reveal a substantial decline in low birth weight resulting from declines in malaria prevalence, especially for first-born children.

Congratulations to these scholars on this impressive accomplishment!

IPUMS DHS is a system that makes it easy to find and review thousands of DHS survey variables and to download a single fully harmonized data file with only the variables and samples that interest you. IPUMS DHS currently includes variables from DHS survey samples from 32 African and 9 Asian countries; more samples are constantly being added.
