PMA2016/Kenya Round 5 Indicators


Summary of the sample design for PMA2016/Kenya-R5:

PMA2020 is designed to create sentinel sites for data collection both at the population level and among service delivery points (SDPs). Enumeration areas (EAs) selected in Round 1 are generally used for data collection in Rounds 2-4. In Round 5 and onwards, data collection is conducted in a new selection of EAs to reduce respondent fatigue within communities that have been surveyed multiple times. Households within the EA are randomly sampled during each round. The original Round 1 sample design summary is provided below as are Round 5 updates (scroll down to the “Sample Design” tab).

PMA2016/Kenya-R5, the fifth round of data collection in Kenya, used a multi-stage cluster design with urban/rural and county as strata. The first stage of sampling was at the county level using probability proportional to size procedures to select 11 out of 47 counties: Nairobi, Kilifi, Nandi, Nyamira, Kiambu, Bungoma, Siaya, Kericho, Kitui, Kakamega, and West Pokot. Kakamega and West Pokot were added during this fifth survey round. Within the 11 selected counties, 151 EAs were then selected by the Kenya National Bureau of Statistics. The sample was powered to generate national estimates of all women mCPR with less than 3% margin of error. The survey was also able to generate estimates on family planning services by including a random sample of up to three private service delivery points within each EA’s boundary. In addition, three public health service delivery points that serve the EA population were also selected—a dispensary, a health center and a referral hospital, either at the sub-county or county level.

Round 1 Sample Design

The PMA2020 survey collects data annually at the national, urban and rural, and, in some countries, selected sub-national levels, to allow for the estimation of key indicators to monitor progress in family planning. The resident enumerator (RE) model enables replication of the surveys twice a year for the first two years, and annually each subsequent year, to track progress.

PMA2014/Kenya Round 1 used a multi-stage cluster design with urban/rural and county as strata. The first stage of sampling was at the county level using probability proportional to size procedures to select nine out of 47 counties: Nairobi, Kilifi, Nandi, Nyamira, Kiambu, Bungoma, Siaya, Kericho and Kitui. Within the nine selected counties, 120 enumeration areas (EAs) were selected proportional to size with urban/rural stratification. The sample was powered to generate national and urban/rural estimates of all woman mCPR with less than 3% margin of error.

In each selected EA, field supervisors randomly selected up to three private service delivery points (SDPs) to be interviewed by an RE using the SDP questionnaire. The field supervisors themselves administered the SDP questionnaires at an additional three public SDPs that serve each EA - the lowest, second-lowest and third-lowest level public health SDPs designated to serve each EA (a dispensary, a health center and a referral hospital), either at the sub-county or county level.


Round 5 Sample Update

A new selection of 120 EAs in the original nine counties (Nairobi, Kilifi, Nandi, Nyamira, Kiambu, Bungoma, Siaya, Kericho, and Kitui) was done by the Kenya National Bureau of Statistics by randomly selecting EAs from the list of EAs that were geographically adjacent to Round 1-4 EAs. In two additional counties, Kakamega and West Pokot, the Kenya National Bureau of Statistics drew 31 new EAs from the master sampling using the same strategy as in Round 1.

All households, health service delivery points and key landmarks in each EA were listed and mapped by the REs to create a frame for the second stage of the sampling process. Field supervisors randomly selected 42 households using a phone-based random number-generating application. A household roster was completed and all eligible women age 15-49 were approached and asked to provide informed consent (and assent if aged 15-17) to participate in the study.

The majority of SDPs are repeated in each round, forming a panel survey. If an EA had more than three private SDPs identified during the listing process, then a new, random sample of three private SDPs is selected during each round.

PMA2020 uses standardized questionnaires for households, females and SDPs to gather data about households and individual females that are comparable across program countries and consistent with existing national surveys. Prior to launching the survey in each country, local experts review and modify these questionnaires to ensure all questions are appropriate to each setting. Three questionnaires were used to collect data from the PMA2016/Kenya-R5 survey: the household questionnaire, the female questionnaire and the service delivery point (SDP) questionnaire. These questionnaires were based on model surveys designed by PMA2020 staff at the Bill & Melinda Gates Institute for Population and Reproductive Health at the Johns Hopkins Bloomberg School of Public Health in Baltimore and fieldwork materials of the 2008-09 Kenyan Demographic and Health Survey (KDHS).

All PMA2020 questionnaires are administered using Open Data Kit (ODK) software and Android smartphones. The PMA2015/Kenya-R5 questionnaires appeared in Kiswahili in addition to English. Female resident enumerators in each enumeration area (EA) administered the household and female questionnaires in selected households.

The household questionnaire gathers basic information about the household, such as ownership of livestock and durable goods, as well as characteristics of the dwelling unit, including wall, floor and roof materials, water sources, and sanitation facilities. This information is used to construct a wealth quintile index.

The first section of the household questionnaire, the household roster, lists basic demographic information about all usual members of the household and visitors who stayed with the household the night before the interview. This roster is used to identify eligible respondents for the female questionnaire. In addition to the roster, the household questionnaire also gathers data that are used to measure key water, sanitation, and hygiene (WASH) indicators, including regular sources and uses of water, sanitation facilities used and prevalence of open defecation by household members.

The female questionnaire is used to collect information from all women age 15 to 49 who were listed on the household roster at selected households. The female questionnaire gathers specific information on: education; fertility and fertility preferences; family planning access, choice and use; quality of family planning services; exposure to family planning messaging in the media; and the burden of collecting water on women.

The SDP questionnaire collected information about the provision and quality of reproductive health services and products, integration of health services, and water and sanitation within the health facility.


The PMA2016/Kenya-R5 fieldwork started with a two-week training of approximately 30 new field staff from the newly added counties of Kakamega and West Pokot. The two-week training and the refresher training were hold in October 2016. For both sets of trainings, staff from the International Centre for Reproductive Health Kenya (ICRH-K), PMA2020/Kenya's implementing partner, led the training with support from PMA2020 staff from the Bill & Melinda Gates Institute for Population and Reproductive Health of the Johns Hopkins Bloomberg School of Public Health.

This 10-day training was followed by a three-day refresher training for the returning field staff. The objective of the refresher training was to address the gaps and errors identified during Round 3 data collection, to understand the questionnaire changes for Round 4, to refresh the knowledge and skills on questionnaire content and the art of asking questions through paired interviews. In addition, field staff were also reminded of key survey protocols they needed to abide by, including consent administration and research ethics. Both trainings both took place in Machakos county, Kenya.

For the two-week training, all training participants were given comprehensive instruction on how to complete the household, female, and service delivery point (SDP) questionnaires. In addition to PMA2020 survey training, all participants received training on contraceptive methods by a Kenyan obstetrician/gynecologist.

Throughout the two-week training, REs and supervisors were evaluated based on their performance on several written and phone-based assessments, mock field exercises and class participation. The training included three days of mock field exercises, during which participants entered a mock enumeration area (EA) to practice listing, mapping and conducting household, female and SDP interviews; recording all responses on their project phones; and submitting to a practice cloud server—a centralized data storage system. The RE trainings were conducted primarily in English, some small group sessions were conducted in Kiswahili.

For the refresher trainings, all training participants were given instructions on survey changes to the tools since the previous round. The REs and supervisors were all evaluated based on their performance on phone-based assessments. Similar to the two-week training, the three-day refresher trainings were conducted primarily in English.

Data Collection and Processing

Data collection was conducted between November and December 2016. Unlike traditional paper-and-pencil surveys, PMA2020 uses ODK Collect, an open-source software application, to collect data on mobile phones. All the questionnaires were programmed using this software and installed onto all project smartphones. The ODK questionnaire forms are programmed with automatic skip-patterns and built-in response constraints to reduce data entry errors.

The ODK application enabled REs and supervisors to collect and transfer survey data to a central ODK Aggregate cloud server. This instantaneous aggregation of data also allowed for concurrent data processing and course corrections while PMA2020 was still active in the field. Throughout data collection, central staff at ICRH-K in Kenya and the data manager at the Gates Institute at Johns Hopkins in Baltimore routinely monitored the incoming data and notified field staff of any potential errors, missing data or problems found with form submissions on the central server. The use of mobile phones combined data collection and data entry into one step; therefore, data entry was completed when the last interview form was uploaded at the end of data collection in December.

Once all data were on the server, data analysts cleaned and de-identified the data, applied survey weights, and prepared the final data set for analysis using Stata® software. Data analysis for preliminary findings was conducted between January and March 2016. The preliminary results were released to the public in June and the national dissemination workshop of the results from the survey round was held on July 14, 2016 at Crowne Plaza Hotel, Nairobi, Kenya.

This table shows response rates for household and female respondents by residence (rural/urban) for PMA2016/Kenya-R5. A total of 6,343 households were selected for the Round 5 survey; 6,239 households were found to be occupied at the time of the fieldwork. Of the occupied households, 6,073 (97.3%) consented to a household-level interview. The response rate at the household level was higher in rural (99.2%) than in urban (94.4%) areas.

In the occupied households that provided an interview, a total of 5,961 eligible women age 15 to 49 years were identified. Overall, 98.9% of the eligible women were available and consented to the interview. The female response rate was slightly higher in the rural (99.3%) relative to the urban (98.2%) enumeration areas (EAs). Only de facto females are included in the analyses; the final completed de facto female sample size was 5,894.
