摘要

背景:政策制定者和项目执行者需要关于低收入和中等收入国家移民和移徙的高质量数据;然而,在这些环境中缺乏高质量的数据。对流动人口进行抽样需要更好的技术。被调查者驱动的抽样(RDS)可能就是这样一种解决方案。目的:以加纳为案例研究,本文的目标是:1)评估RDS招聘效率、网络规模和内部移民的联系;2)同质性检验;3)详细介绍在加纳实施RDS的成功和挑战,以及如何将这些经验教训应用于其他中低收入国家的移民人口。方法:本研究采用随机抽样调查方法对625名在加纳阿克拉从事市场搬运工(kayayei)的农村-城市女性移民进行了抽样调查。结果:本研究产生了迄今为止最全面的关于kayayei的数据集。随着参与者受教育程度的提高和更频繁地迁移到阿克拉,网络规模也在扩大。族裔群体的成员资格是招聘的一个重要决定因素,某些群体倾向于从内部招聘。雇用卡亚伊族人收集数据建立了至关重要的信任。结论:虽然RDS不是对低收入和中等收入国家难以接触到的移民进行抽样调查的一刀切的解决方案,但它可以成为发现和招募难以接触到的移民人口的有力工具。在拥有多个民族语言群体的国家,招募具有更多民族语言重叠的移民人口可以促进更快的平衡。贡献:本研究扩大了低收入和中等收入国家流动人口使用RDS的证据基础,并提供了经验教训,以帮助其他研究人员在低收入和中等收入国家实施RDS。

Collecting data from migrants in Ghana: lessons learned using respondent-driven sampling
Background: Policymakers and program implementers require high-quality data on migrants and migration in low- and middle-income countries (LMIC); however, a shortage of high-quality data exists in these settings. Sampling migrant populations requires better techniques. Respondent-driven sampling (RDS) may be one such solution. Objective: Using Ghana as a case study, the objectives of this paper are to: 1) assess RDS recruitment productivity, network size, and ties of internal migrants; 2) test for homophily; and 3) detail the successes of and challenges to implementing RDS in Ghana and how these lessons can be applied to migrant populations in other LMIC settings. Methods: This study used RDS to sample 625 rural–urban female migrants working as market porters (kayayei) in Accra, Ghana. Results: This study generated the most comprehensive data set on kayayei to date. Network size increases as participants become more educated and migrate more often to Accra. Ethnic group membership is an important determinant of recruitment, with certain groups preferring to recruit from within. Employing members of the kayayei population to collect data built crucial trust. Conclusions: Whilst RDS is not a one-size-fits-all solution for sampling hard-to-reach migrants in LMIC, it can be a powerful tool to uncover and to recruit hard-to-reach migrant populations. In countries with multiple ethnolinguistic groups, recruiting a migrant population with greater ethnolinguistic overlap may facilitate quicker equilibrium. Contribution: This study expands the evidence base on use of RDS among migrant populations in LMIC and provides lessons learned to assist other researchers implementing RDS in LMIC settings.
