Other Household Survey [hh/oth]
The World Bank is providing technical and financial support to countries to help mitigate the spread and impact of the new corona-virus disease (COVID-19). One area of support is for data collection to inform evidence-based policies that may help mitigate the effects of this disease. Towards this end, the World Bank is leveraging the West Africa Economic Monetary Union (WAEMU) Household Survey harmonization Project (P153702) to produce high frequency longitudinal data in member countries (Benin, Burkina Faso, Chad, Cote d’Ivoire, Guinea Bissau, Mali, Niger, Senegal and Togo).
For Burkina Faso, the survey, which is implemented by the Institut National de la Statistique et la Demographie (INSD), is conducted using cell phone numbers of household members collected during the 2018/19 EHCVM survey. The extensive information collected in the EHCVM provides a rich set of background information for the COVID-19 High Frequency Phone Survey of households. This background information can be leveraged to assess the differential impacts of the pandemic in the country. Every month, the sampled households will be asked a set of core questions on the key channels through which individuals and households are expected to be affected by the COVID-19-related restrictions. Employment, access to basic services, non-labor sources of income are channels likely to be impacted. The core questionnaire is complemented by questions on selected topics that rotate each month. This provides data to the government and development partners in near real-time, supporting an evidence-based response to the crisis.
The main objectives of the survey are to:
• Identify type of households directly or indirectly affected by the pandemic;
• Identify the main channels by which the pandemic affects households;
• Provide relevant data on income and socioeconomic indicators to assess the welfare impact of the pandemic.
Phase 1 was conducted on a monthly basis during the period of June 2020 and July 2021 for11 Rounds. Phase 2 (starting from Round 12) was conducted on a bi-monthly basis starting in April 2022. Phase 3 (starting from Round 18) will be conducted on a bi-monthly basis, starting in July 2023.

Sampling
The sample of the HFS is a subsample of the 2018/19 Harmonized Living Conditions Household Survey (EHCVM). The EHCVM 2018/19 is built on a nationally and regionally representative sample of households in Burkina Faso. EHCVM 2018/19 interviewed 7,010 households in urban and rural areas. In the EHCVM interview, households were asked to provide phone numbers of the household head, or a household member, or a non-household member (e.g. friends or neighbors) so that they can be contacted for follow-up questions. At least one valid phone number was obtained for 6877 households. These households established the sampling frame for the HFS. To obtain representative strata at the national, capital (Ouagadougou), urban, and rural level, the target sample size for the HFS is 1,800 household (assuming a 50% non-response rate the minimum required sample is 1479). To account for non-response and attrition, 2500 households were called in baseline round of the HFS. 1,968 households were fully interviewed during the first round of interviews. Those 1,968 households constitute the final successful sample and will be contacted in subsequent rounds of the survey.
In addition to the 1,968 households successfully interviewed in Round 1, in Round 2, 242 additional households were sampled from the rural strata, in order to increase the representativeness in this domain. In Round 12, 231 additional households were selected from the rural stratum from the 2018/19 EHCVM sample. In Round 18, 858 additional households were selected from panel component of the 2021/22 EHCVM sample.
BASELINE (ROUND 1): All 2500 households were called in the baseline round of the phone survey. 82.48 percent of sampled households were successfully contacted. Of those contacted, 1,968 households were fully interviewed. These 1,968 households constitute the final successful sample and will be contacted in subsequent rounds of the survey.
ROUND 2: Interviewers attempted to contact and interview all 1,968 households that were successfully interviewed in the Round 1 of the BFA COVID-19 HFPS. 1,891 households (96.1% of the 1,968 attempted) were contacted and 1,860 (94.5%) were successfully interviewed in the second round. Of those contacted, 20 households refused outright to be interviewed and 12 were partially interviewed. In addition to the 1,968 households successfully interviewed in Round 1, in Round 2 242 additional households were sampled from the rural strata, in order to increase the representativeness in this domain. Out of the 242 sample households, 177 households (73.14% of the 242 attempted) were contacted and successfully interviewed. The entire Round 2 sample comprises 2037 households.

RESPONDENTS: Each round of the Burkina Faso COVID-19 HFPS has ONE RESPONDENT per household. The respondent was the household head or a knowledgeable adult household member. The respondent must be a member of the household. Unlike many other household surveys, interviewers were not expected to seek out other household members to provide their own information. The respondent may still consult with other household members as needed to respond to the questions, including to provide all the necessary information on each household member.
Interviewers were instructed to make every effort to reach the same respondent in subsequent rounds of the survey, in order to maintain the consistency of the information collected. However, in cases where the previous respondent was not available, interviewers would identify another knowledgeable adult household member to interview.
To obtain unbiased estimates from the sample, the information reported by households needs to be adjusted by a sampling weight (or raising factor) w_h. To construct the sampling weights, we follow the steps outlined in Himelein, K. (2014), which outlines eight steps, of which we follow six, to construct the sampling weights for the BFA-HFPS:
- Begin with base weights from the EHCVM 2018/19 for each household
- Incorporate probability of sub-selection of round 1 unit for each of the phone survey households. We calculate the probability of selection for each of the 3 strata in the EHCVM (urban, rural and other urban) by creating the numerators as the number of completed phone interviews and the denominator as the number of households in the EHCVM for each stratum.
- Pool the weights in Steps 1 and 2.
- To cater for non-responses, derive attrition-adjusted weights for all individuals by running a logistic response propensity model based on characteristics of the household head (i.e. education, labor force status, demographic characteristics), characteristics of the household (consumption, assets, financial characteristics), and characteristics of the dwelling (house ownership, overcrowding).
- Trim weights by replacing the top two percent of observations with the 98th percentile cut-off point; and
- Post-stratify weights to known population totals to correct for the imbalances across our urban and rural sample. In doing so, we ensure that the distribution in the survey matches the distribution in the EHCVM 2018/19.

The Burkina Faso - COVID-19 High Frequency Phone Survey was conducted using Computer Assisted Telephone Interview (CATI) techniques. The survey team was composed of 20 enumerators and 5 supervisors. Each enumerator was given a tablet and mobile phone (including sim card and data bundles) to be used for the interviews. The household questionnaire was implemented using the CAPI software Survey Solutions.
ORGANIZATION OF FIELDWORK: Data were collected by trained NBS INSD interviewers who individually made phone calls from their respective homes. Since the country was on lockdown during the preparation and data collection exercise for the baseline round, interviewers were not allowed to be in the office. Therefore, all interviews were conducted from interviewers’ homes. Although the lockdown restrictions were partially lifted following the baseline, interviewers will continue to conduct interviews from home in subsequent rounds until it is deemed safe for them to return to the office. Every day, completed and partially completed call were reviewed and data were synchronized each evening.
PRE-LOADED INFORMATION: Basic information on every household was pre-loaded in the CATI assignments for each interviewer. The information was pre-loaded to (1) assist interviewers in calling and identifying the household and (2) ensure that each pre-loaded person is properly addressed and easily matched to the most recent interviews. Basic household information (location, household head name, phone number, etc.) was pre-loaded. The list of individuals from the previous interview and their basic characteristics were uploaded. This helped maintain the panel of individuals and ensured the status of each individual in the subsequent round of the survey.
Data processing
At the end of data collection, the raw dataset was cleaned by the INSD with the support of the WB team. This included formatting, and correcting results based on monitoring issues, enumerator feedback and survey changes.
