Living Standards Measurement Study [hh/lsms]
The Benin EHCVM 2021-2022 is the second edition of a nationally representative household survey conducted within the West Africa Economic Monetary Union (WAEMU) Household Survey harmonization Project (P153702) a joint program by the World Bank and the WAEMU Commission that aims at producing household survey data in member countries (Benin, Burkina Faso, Chad, Cote d’Ivoire, Guinea Bissau, Mali, Niger, Senegal and Togo). The survey covers all regions and includes approximately 8,000 households.
The Benin EHCVM 2021-2022 is implemented by the National institute of Statistics and Economical Analysis (INSAE) with support from the World Bank and the WAEMU Commission. The objective of the program is to strengthen the capacity of its member countries (Benin, Burkina Faso, Cote d’Ivoire, Guinee Bissau, Mali, Niger, Senegal, and Togo) to conduct living conditions surveys that meet harmonized, regional standards and to make the collected micro-data publicly accessible. The EHCVM is a nationally representative survey of 8,000 households, which are also representative of the geopolitical zones (at both the urban and rural level).
The survey uses two main survey instruments: a household/individual questionnaire, and a community-level questionnaire. The surveys took place in two waves with each wave covering half of the sample. The first wave was fielded between November 2021 and January 2022, while the second wave occurred between April 2022 and July 2022. The two-wave approach was chosen to account for seasonality of consumption.

Sampling
The sampling frame for the 2018/19 survey was based on the fourth general population and housing census (RGPH4) of 2013. In 2021/22, an enumeration was conducted in the same clusters and the sampling plan is based on that of the 2018/19 survey.
The 2018/19 survey sample was drawn according to a two-stage stratified sampling plan. The stratum is the combination of department/residence area. In each stratum, clusters (primary sampling units) were chosen at the first stage with a probability proportional to their size in terms of the number of households. At the second stage, 12 households were chosen with equal probability within each cluster. This frame contains 10032 enumeration areas, is nationally representative, and covers all regions with urban and rural areas surveyed in all regions apart from Littoral, a purely urban region. In Benin, the survey design decided on the sample size using the poverty rate - obtained from the 2011 Integrated Modular Survey on living conditions of households - as a variable of interest. Then the survey design split the decided sample size among regions considering the number of households in the region and the necessity to minimize the relative error. The survey design also defined the domains as country, urban and rural areas, and each of the 12 regions. Taking this into account, 23 explicit sample strata were selected.
Upon deciding on the sample size and repartition, the survey design team implemented a 2-stage sampling methodology. At the first stage, 670 enumeration areas (EAs) were selected with Probability Proportional to Size (PPS) using the 2013 RGPH and the number of households as a measure of size. In the second stage, 12 households were selected in each enumeration area randomly.
The total estimated survey sample size was 8040 households - 3960 from urban areas and 4080 from rural areas. After that, the survey design randomly divided each enumeration area into two equal groups. The survey team interrogated the first group in wave 1 and the other in wave 2. Finally, for various reasons, including availability and quality monitoring, the final sample size comprises 8032 households, including 3952 households from urban areas and 4080 households from rural areas. In wave one, the survey teams interviewed 4013 households (1949 in urban areas and 2064 in rural areas. In wave two, the teams interviewed 4019 households (2003 in urban areas and 2016 in rural areas).
Survey instrument
The Benin ECHVM 20221/22 consists of two questionnaires for each of the two visits. The Household Questionnaire was administered to all households in the sample. The Community Questionnaire was administered to the community to collect information on the socio-economic indicators of the enumeration areas where the sample households reside.
EHCVM 2021/22 Household Questionnaire: The Households Questionnaire provides information on demographics; education; health; employment (including activity-related information, primary and secondary employments); nonjob revenues; saving and credit (including information for payments due for 15 years old members of the household); food consumption; food security; nonfood consumption; nonagricultural enterprises; housing; household’s assets; transfers (received and sent); shocks and survival strategies; safety nets; agriculture (including information on plots, costs of inputs, and crops); livestock; fishing; agricultural equipment; and a module that provides indicators to helps users situate the household on the poverty spectrum based on subjective considerations and comparative indicators.
EHCVM 20221/2222 Community Questionnaire: The Community Questionnaire solicits information on general community’s characteristics; community access to infrastructure and to social services; community agricultural activity; community participation; and local retail price information.

- Computer Assisted Personal Interview [capi]
Interviews were conducted by teams of enumerators. Each team comprised three enumerators and a team lead. In each team, the three members were responsible for administering the household questionnaire and the market price data collection, while the team lead was responsible for administering the community questionnaire.
Overall, six supervisors for the 30 teams were constituted for this survey. This represents a total of 5 teams per supervisor. The supervision team conducted five technical supervision missions and one administrative and financial mission during the data collection phase. Control occurred at two levels: On the field, with team leaders double-checking data collected by team members, and at the headquarters, where four control agents were recruited to edit the data synchronized on the online data collection tool.
