High Frequency Phone Survey on Internally Displaced Persons (IDP) 2021
Enquête téléphonique à haute fréquence sur les personnes déplacées à l'intérieur du pays (PDI) au Burkina Faso, 2021
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 coronavirus disease (COVID-19). One area of support is for data collection to inform evidence-based policies that may help mitigate the effects of this crisis. Towards this end, a phone survey of 11 rounds were implemented in Burkina Faso. The last three rounds, implemented in May to July 2021 included a sample of internally displaced households.
The COVID-19 pandemic is significantly having short term and long term impact on Burkinabe households’ welfare, impacting households through at least three broad channels: (i) the income/employment channel, which includes both labor and non-labor income, (ii) the price channel, and (iii) the long-term human capital channel. Most of these impacts are related to the direct health effect, but also to the containment measures that systematically altered socio-economic activities, resulting in a reduction of income across the board. Due to the urgent need for timely data and the limits on face-to-face surveys, the World Bank and the National Institute of Statistics and Demography (INSD) decided to implement a high-frequency phone survey of national households (HFPS) (https://microdata.worldbank.org/index.php/catalog/3768) to monitor the effects of COVID-19 on households, leveraging the available household phone number in the 2018/19 Enquete Harmonisée sur les Conditions de Vie des Ménages (EHCVM).
In Burkina Faso, the forcibly displaced persons (FDP) include both refugees and internal displaced population. For security related issues, FDPs are predominantly internal displaced people (IDPs). According to recent studies, the number of internally displaced people soared from 87,000 in January 2019 to over 1 million in August 2020, an increase of more than 1000 per cent (Conseil National de Secours d'Urgence et de Réhabilitation – CONASUR, 2020). The unprecedented levels of displacement occurred as the coronavirus pandemic worsens an already critical humanitarian crisis in the violence-stricken country. This critical situation calls for the need of timely data and analysis especially during a pandemic for this vulnerable group in order to better inform policy and targeting programs. Given the mutual interest of the INSD, WB-UNHCR Joint Data Center on Forced Displacement (JDC), UNHCR, and World Bank, decision was made to further expand the sample of the high-frequency phone survey of national households (HFPS) to include IDPs for a total of three consecutive rounds.
The core survey questionnaire of the Burkina Faso High Frequency Phone Survey on IDPs (BFA HFPS-IDP) is designed to cover important and relevant topics like employment, access to basic services and items, and non-labor sources of income. The core questionnaire is complemented by questions on selected topics that rotate each month, including knowledge of Covid-19 spread, social distancing and behavior, coping mechanisms to shocks, fragility, conflict and violence. Selected topics may be investigated more in detail in specific rounds.
The BFA HFPS-IDP is fielded alongside the Burkina Faso Covid-19 High Frequency Phone Survey of national households. Rounds 1, 2 and 3 of data collection for the HFPS-IDP occur simultaneously with round 9, 10 and 11 of the national HFPS operation, respectively.

The IDP sample is drawn from an IDP database named CONASUR database which serves as the sampling frame. The CONASUR has been developed and supported by the government of Burkina Faso with the technical and financial support of development partners, including UNHCR, IOM and OCHA. The CONASUR database is updated regularly, and has exhaustive list of refugees and IDPs, along with few socio-demographic characteristics, as well as information on the phone numbers of households. The sample is drawn from the 9 regions (out of 12) where the presence of IDPs is more relevant: Boucle du Mouhoun, Cascades, Centre-Est, Centre-Nord, Est, Hauts-Bassins, Nord, Plateau Central, Sahel. It is important to note that the BFA HFPS-IDPs is representative of households that have access to phones. Taken that into consideration, a key concern is the bias introduced by sampling households with at least a phone number, as phone penetration in some regions/areas might be limited. However, according to data from the CONASUR database, the percentage of households with at least one phone number is very high, accounting for above the 74% in all the sampled regions.
To account for non-response and attrition, 1500 households were selected in baseline round of the HFS. 1,166 households were fully interviewed during the first round of interviews. The final successful sample have been contacted in subsequent rounds of the survey.
BASELINE (ROUND 1): All 1500 households were called in the baseline round of the phone survey. 73.75 percent of sampled households were successfully contacted. Of those contacted, 1,156 households were fully interviewed. These 1,156 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 1,156 households that were successfully interviewed in the Round 1 of the BFA COVID-19 HFPS. 1,114 households (96.3% of the 1,156 attempted) were contacted and 1,112 (96.1%) were successfully interviewed in the second round. Of those contacted, 2 households did not answer due to a language barrier.
ROUND 3: Interviewers attempted to contact and interview all 1,112 households that were successfully interviewed in the Round 2 of the BFA COVID-19 HFPS. 1,051 households (94.53% of the 1,112 attempted) were contacted and 1,048 (94.24%) were successfully interviewed in the third round. Of those contacted, 1 household refused the interview and 2 were only partially interviewed.
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:
1. Begin with base weights. Base weights will equal 1 for all intents and purposes.
2. Derive attrition-adjusted weights for all individuals by running a logistic response propensity model based on household characteristics as well as the characteristics of the dwelling. While the CONASUR database is limited in the number of socioeconomic variables, we have characteristics of the household head and household.
3. Trim weights by replacing the top two percent of observations with the 98th percentile cut-off point; and
4. Post-stratify weights to known population totals to correct for the imbalances across the sample. In doing so, we ensure that the distribution in the survey matches the distribution in the CONASUR database.

Data Collection Notes
The 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 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.
