PMA collects a nationally or sub-nationally representative sample of data from households and women in selected sentinel sites, to estimate family planning and other health indicators on an annual basis in nine pledging FP2020 countries. The PMA surveys involve interviewing a sample of females aged 15 to 49 years and a probability sample of health facilities, pharmacies, and retail outlets that offer family planning services to the selected communities. The female respondents are asked questions about their background, their birth history and fertility preferences, their use of family planning methods, and other information that is helpful to policymakers and program administrators in health and family planning improvement.
The survey sample in each country is based on a multi-stage cluster design, typically using urban-rural and major regions as the strata. A nationally representative number of geographical clusters ("enumeration areas") is sampled in each program country. In each enumeration area, households are listed and mapped. Households are systematically sampled for inclusion in the survey round, using random selection. Embedded in each household survey is the female respondent survey, with a series of questions for all women of reproductive age (15-49) living at each household. Respondents for the service delivery point survey are management staff answering on behalf of the facility.
The household and female surveys are carried out by female data collectors, known as resident enumerators (REs). Eligibility criteria for selection of REs vary by program country. REs are typically women over the age of 21 who are from or near the respective enumeration areas and hold at least a high school diploma.
Each RE takes about six weeks to collect data from all selected households, eligible women, and service delivery points. Data collected from households generate aggregate numbers (descriptive statistics). Data processing produces weighted estimates to report to national and international stakeholders. Data are immediately processed when collection is completed, and the results are disseminated to country stakeholders. Data collection takes place semi-annually in the first two years for each project country and annually thereafter.
What's new with PMA's survey methodology?
Starting in 2019, PMA is adding new features to the survey design to enhance data utilization and action.
- PMA is implementing a panel design with embedded cross-sectional surveys, enabling improved measurement of changing contraceptive use dynamics and causal factors
- Generating a set of core questions that include capture of contextual community norms as well as individual aspirations, intentions, and empowerment, plus adolescent-specific questions.
- Customizing an added set of questions to meet the needs of country governments and stakeholders, including intervention exposure.
PMA uses a two-stage cluster design with typically urban-rural and major regions as the strata. A representative sample of enumeration areas (EAs) are drawn from a master sampling frame covered, usually provided by the national statistical agency in each country. Ahead of data collection, households, and key landmarks in each EA are listed and mapped by resident data collectors. Within each EA at baseline, a random sample of households is selected. The survey aims to include a sample size that would allow analysts to calculate a national estimate for all indicators, including calculating the modern contraceptive prevalence rate (mCPR) with a margin of error of ±3 percentage points. The target sample assumed an expected number of eligible women per household and accounted for non-response rates and loss to follow-up. At baseline, all resident eligible females are contacted and consented for interviews. Up to three private SDPs within the EA were also selected for interviews along with the public health posts, district hospitals and regional hospitals serving the EA.

The PMA platform collects data that are comparable across all program countries and consistent with existing nationally representative surveys. To accomplish this, PMA developed standard household, female, service delivery point, and client exit interview questionnaires. These standard questionnaires are reviewed and modified prior to program launch in each country, to ensure questions are appropriate to each setting. Country-specific questions are also added that reflect programmatic priorities for stakeholders.
Below are links to standard questionnaires that include a set of core questions that are adapted prior to data collection to be country and round-specific.
