Enquête Ménage sur la Migration et les Transferts de Fonds 2009 - Burkina Faso

Abstract
---------------------------

The main objective of the assignment is to contribute to the improvement of migration and remittances impact on development in sub-Saharan Africa. Some specific objectives are to provide better understandings of migration and remittances through household surveys. By enhancing the knowledge regarding migrant remittances sending or receiving, these data will be a reliable input for policy-makers. The survey will provide information on migrant and non-migrant households' socioeconomic characteristics and how they send remittances back home. Appropriate approach and methodology will be applied to carry out the survey activities for high quality data.

Geographic coverage
---------------------------

Ten most intensive migration provinces in Burkina Faso: Banwa, Boulgou, Boulkiemdé, Kadiogo, Namentenga, Passoré , Sanmatenga, Sourou, Tuy and Yatenga.

Sampling procedure
---------------------------

The sampling approach was chosen to focus on international migration and remittances. It has ensured an adequate representation of migration density in Burkina Faso. First we used the Burkina Faso Census 2006 that includes questions on demographic and migration. Then we calculated the incidence of international migration for each of the 45 provinces in Burkina Faso. We chose the largest 10 provinces which have the highest international migration incidence. The universe for this survey is the households that are placed in these provinces. After chosen the universe of households, we have adopted a two stages sampling: i) village/town sector and ii) household. Migration scope is different depending on the province or rural/urban area in Burkina Faso. We determine the number of village to be selected in each province according to the international migration incidence of each province. In total we selected 78 villages out of 2,273 villages for the 10 provinces.

Village town sector selection

The first stage of sampling consisted of villages and towns selection. We randomly selected the village/town sector within each province with equal probability. We have considered a village/town sector sample size of 27 households. We distributed the 27 households according to the following rule: 9 households with international migrants, 9 households with internal migrants and 9 households with no migrants. Thus, the whole sample is composed of 78 villages/towns sectors for 2,106 households. Considering migration density in each province, a number of villages/town sectors were randomly selected by province. In big town as Ouagadougou, each sector was considered as a village.

Household selection

The second sampling stage was household selection. Households were randomly selected after doing an exhaustive and quick household census in the selected village. For the villages in rural areas, we listed all the households in the village. The listing survey was not done for all households in town: we have randomly selected about 120 households in each selected town sector around a random start point. This number is extended if needed in order to attend the household type quotas. We have determined this point by using the town addressing codes. The process consisted of selecting randomly a street code and an avenue code which constituted the two elements of the start point. The main objective of the census is the household sampling. It provides information on the head household name, household size and household category (households without migrants, households with internal migrants and households with international migrants). The sub sample size for each household category is 9 in selected village/town sector. These households are randomly selected among the total households of the category from the quick census.

Mode of data collection
---------------------------

Face-to-face [f2f]

Research instrument
---------------------------

8 section questionnaire designed in English by the World Bank Migration and Remittance Team with the collaboration of the survey implementation team staff. This questionnaire has been translated into French by the survey team staff and submitted to pre-test and pilot in area with similar migration and remittance characteristics to the survey zone.

Cleaning operations
---------------------------

Data have been cleaned using STATA software. The double entry process was the first level of dataset quality control. Several consistency and cross checking rounds have been done in order to ensure a high dataset quality. This process often needed to check error using the hard completed questionnaires. Very few errors have been unsolved. We made no imputation for missing data in the dataset.

Response rate
---------------------------

Most of the questionnaires (99%) have been completed at the first visit. The non response rate is very low: 4 households out of 2106 have not responded. This score could be explained by the census process during which the high experienced team prepared the household for interview if it coma to be selected.

摘要
--------------------------------
本任务的宗旨在于为撒哈拉以南非洲地区移民与汇款对发展的影响提升改进贡献力量。具体目标包括通过家庭调查深化对移民与汇款的认知，并借此增强对汇款发送或接收的迁移者信息了解，以确保这些数据成为政策制定者的可靠依据。调查将提供有关移民及非移民家庭的社会经济特征以及他们如何汇款回家的信息。将采用适宜的方法论以确保调查活动的高质量数据收集。

--------------------------------
布基纳法索十个移民密集省份：班瓦、博尔古、博利克迪、卡迪奥戈、南门腾加、帕索雷、桑马滕加、索鲁、图伊和亚滕加。

抽样程序
--------------------------------
抽样方法的选择旨在聚焦于国际移民与汇款，以确保布基纳法索移民密度的充分代表。首先，我们利用包含人口和移民问题的2006年布基纳法索人口普查数据。然后，我们计算了布基纳法索45个省份的国际移民发生率。我们选择了十个国际移民发生率最高的省份。本调查的总体是位于这些省份的家庭。在选定家庭总体后，我们采用了两阶段抽样：i) 村庄/城镇区域；ii) 家庭。布基纳法索不同省份或农村/城市地区的移民范围存在差异。我们根据每个省份的国际移民发生率确定每个省份要选定的村庄数量。在十个省份中，总共从2,273个村庄中选择了78个村庄。
村庄/城镇区域选择

抽样的第一阶段包括村庄和城镇的选择。我们以等概率随机选择每个省份内的村庄/城镇区域。我们考虑的村庄/城镇区域样本规模为27户。我们将27户家庭根据以下规则分配：9户有国际移民的家庭、9户有国内移民的家庭和9户无移民的家庭。因此，整个样本由78个村庄/城镇区域组成，覆盖2,106户家庭。考虑到每个省份的移民密度，根据省份随机选择了若干个村庄/城镇区域。在大型城镇如瓦加杜古，每个区域被视为一个村庄。
家庭选择

抽样的第二阶段是家庭选择。在选定的村庄进行彻底而快速的 household 户口普查后，随机选择了家庭。对于农村地区的村庄，我们列出了村庄中所有的家庭。在城镇中，并未对所有家庭进行普查：在每个选定的城镇区域，我们随机选择大约120户家庭，从随机起点开始。如果需要，此数量将根据家庭类型配额进行扩展。我们通过城镇地址代码确定这一点。普查的主要目的是家庭抽样，它提供了关于户主姓名、家庭规模和家庭类别（无移民家庭、国内移民家庭和国际移民家庭）的信息。在选定的村庄/城镇区域中，每个家庭类别的子样本规模为9。这些家庭从快速普查的总家庭中随机选择。
数据收集方式
--------------------------------
面对面 [f2f]
研究工具
--------------------------------
由世界银行移民与汇款团队与调查实施团队工作人员合作设计的包含8个部分的英文问卷。该问卷由调查团队工作人员翻译成法语，并提交到与调查区域具有相似移民和汇款特征的地区进行预测试和试点测试。
数据清洗操作
--------------------------------
使用 STATA 软件对数据进行清洗。双重录入过程是数据集质量控制的第一个层次。已经进行了多次一致性检查和交叉核对，以确保数据集的高质量。此过程通常需要检查使用完成的纸质问卷中的错误。未解决的错误非常少。我们在数据集中未对缺失数据进行插补。
响应率
--------------------------------
大多数问卷（99%）在第一次访问时已完成。非响应率非常低：2106户中有4户未响应。这一得分可以解释为普查过程，在此过程中，经验丰富的团队为可能被选中的家庭做好了访谈准备。
