Round 1 Sample Design

For the first round of data collection in Burkina Faso, the project used a two-stage cluster design and drew a sample of 53 enumeration areas (EAs) from the national sample frame. The EAs were selected systematically with probability proportional to size within urban and rural strata. The Institut Superieur des Sciences de la Population (ISSP) provided the selection probabilities for the º£½Ç»»ÆÞ2020 sampled clusters which were used to construct sample weights.

Before the first round of data collection, all households, private service delivery points (SDPs) and key landmarks in each EA were listed and mapped by trained resident enumerators (REs) to create a sampling frame for the second stage of sampling for households and private SDPs. The mapping and listing process took place during the first week of data collection in each EA with the help of cartographers and supervisors. Once households had been listed, field supervisors systematically selected 35 households per EA using a random number generating mobile-phone application. All members of the selected households were enumerated by the interviewers when completing household questionnaires. From this household roster, all eligible women (aged 15-49) were approached and asked to provide informed consent to participate in the study.

Up to three private SDPs located within each EA were selected from the list of SDPs available in the EA. In addition, three public SDPs, primary health centers, secondary medical centers with or without a surgery units and tertiary regional or national/teaching hospitals serving the selected EA populations were selected.

Weights were adjusted for non-response and applied to all estimations at the household and individual level in the presented tables.

Round 3 Sample Update

In Round 3, additional 35 EAs were added to the sample making the total sample size 83 EAs. These new EAs were also retained in Round 4.

Round 5 Sample Update

The sample was refreshed for data collection in Round 5. A new sample of 83 EAs was selected by the Institut Superieur des Sciences de la Population (ISSP) to achieve representativeness at a national scale. The EAs were selected systematically using probability proportional to size within urban/rural strata, and whenever possible, were contiguous to an EA used in previous rounds.

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 35 households and up to 3 private SDPs using a phone-based random number-generating application.

Round 6 Sample

Burkina Faso Round 6 used the same sample as in Round 5. In each of the 83 EAs, 35 households and up to three private service delivery points (SDPs) were selected. Up to three public SDPs serving that EA were also selected. Households were systematically selected using a random number generator application. Occupants in selected households were enumerated, and eligible women age 15-49 were contacted and consented for interviews. Data collection was conducted between December 2018 and January 2019.

º£½Ç»»ÆÞ2020 uses standardized questionnaires to gather data about households, individual females and health service delivery points 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. All questionnaires were previously translated into French, the national language of Burkina Faso, and translations were reviewed for appropriateness. Three questionnaires were used to collect º£½Ç»»ÆÞ2019/Burkina Faso R6 survey data: the household questionnaire, the female questionnaire and the service delivery point questionnaire.

The household, female and service delivery point questionnaires were based on model questionnaires designed by º£½Ç»»ÆÞ2020 staff at the Bill & Melinda Gates Institute for Population and Reproductive Health of the Johns Hopkins Bloomberg School of Public Health, the Institut Supérieur des Sciences de la Population (ISSP) of the University of Ouagadougou and fieldwork materials of the Burkina Faso Demographic and Health Survey (DHS).

All º£½Ç»»ÆÞ2020 questionnaires are administered using Open Data Kit (ODK) software and Android smartphones. Given that º£½Ç»»ÆÞ2020 questionnaires are typically administered in local languages, supervisors and Resident Enumerators (REs) worked in small teams during training prior to the data collection to review standard translations orally in the local languages typically used by REs to administer surveys in their EAs. The interviews were conducted in the local language, or French in a few cases when the respondent was not comfortable with the local language, the RE did not speak the maternal language of the respondent, or the respondent was more comfortable in French. REs in each enumeration area administered the household and female questionnaires in the selected households. Field supervisors administered the SDP questionnaire among public SDPs.

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 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 WASH facilities used 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 including education; fertility and fertility preferences; family planning access, choice and use; quality of family planning services; and exposure to family planning messaging in the media.

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 SDP.

Training

The º£½Ç»»ÆÞ2020 Burkina Faso-R6 fieldwork training started in November 2018 with a five-day training for the new resident enumerators (REs) followed by a five-day refresher training of all continuing staff on the project, including supervisors and returning REs. Institut Supérieur des Sciences de la Population (ISSP) º£½Ç»»ÆÞ2020 project staff led both the new and refresher trainings, with limited remote support from the º£½Ç»»ÆÞ2020 team from the Bill & Melinda Gates Institute for Population and Reproductive Health of the Johns Hopkins Bloomberg School of Public Health. The training was held in Ouagadougou, at ISSP, housed within the University of Ouagadougou.

Throughout the training, REs and supervisors were evaluated based on their performance on several written and phone-based assessments, mock field exercises and class participation. The RE training sessions were conducted primarily in English, whereas small group sessions were all conducted in the local languages predominantly spoken in the selected EAs.

Supervisors received additional training prior to and after the RE training to further strengthen their supervisory skills, including instruction on conducting re-interviews, carrying out random spot checks, and engaging communities through local leaders.  

Data Collection & Processing

Data collection was conducted between December 2018 and January 2019. Unlike traditional paper-and-pencil surveys, º£½Ç»»ÆÞ2020 uses Open Data Kit (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 º£½Ç»»ÆÞ2020 was still active in the field. Throughout data collection, central staff at ISSP in Ouagadougou, Burkina Faso and the data manager at the Gates Institute at Johns Hopkins in Baltimore, Maryland 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.

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® version 15 software.

The table shows response rates for household and female respondents by residence (rural/urban) for º£½Ç»»ÆÞ2019/Burkina Round 6. A total of 2,909 households were selected for the survey; 2,809 households were found to be occupied at the time of the fieldwork. 2,763 of the occupied households consented to and completed a household-level interview. The response rate for the household level was higher in the rural (99.6%)  relative to the  urban (97.1%) enumeration areas (EAs). 

In the occupied households that provided an interview, a total of 3,408 eligible women aged 15 to 49 years were identified. Overall, 97.7% of the eligible women were available and consented to and completed the interview. The female response rate was higher in the rural (98.4%) relative to the urban (96.9%) EAs. Only de facto females are included in the º£½Ç»»ÆÞ analyses; the final completed de facto female sample size was 3,329 (unweighted).  

The final service delivery point (SDP) sample included 101 facility interviews , of which 96 were completed, for a response rate of 95.1%. 

Weights were adjusted for non-response at the household and individual levels and applied to all household and individual estimates in this report. SDP estimates are not weighted.
