Crowdsourcing was recognized as having the potential to collect information rapidly, inexpensively and accurately. U-Report is a mobile empowerment platform that connects young people all over the world to information that will change their lives and influence decisions. Previous studies of U-Report's effectiveness highlight strengths in the timeliness, low cost and high credibility for collecting and sending information, however they also highlight areas to improve on concerning data representation. EquityTool has developed a simpler approach to assess the wealth quintiles of respondents based on fewer questions derived from large household surveys such as Multiple Indicators Cluster Surveys (MICS) and Demographic and Health Surveys (DHS).
The methodology of Equity Tool was adopted to assess the socio-economic profile of U-Reporters (ie, enrolled participants of U-Report) in Bangladesh. The RapidPro flow collected the survey responses and scored them against the DHS national wealth index using the EquityTool methodology. This helped placing each U-Reporter who completed all questions into the appropriate wealth quintile.
With 19% of the respondents completing all questions, the respondents fell into all 5 wealth quintiles, with 79% in the top-two quintiles and only 21% in the lower-three resulting in an Equity Index of 53/100 where 100 is completely in line with Bangladesh equity distribution and 1 is the least in line. An equitable random sample of 1828 U-Reporters from among the regular and frequent respondents was subsequently created for future surveys and the sample has an Equity Index of 98/100.
U-Report in Bangladesh does reach the poorest quintiles while the initial recruitment skews to respondents towards better off families. It is possible to create an equitable random sub-sample of respondents from all five wealth quintiles and thus process information and data for future surveys. Moving forward, U-Reporters from the poorly represented quintiles may be incentivized to recruit peers to increase equity and representation. In times of COVID-19, U-Report in combination with the EquityTool has the potential to enhance the quality of crowdsourced data for statistical analysis.
众包被认为具有快速、廉价和准确地收集信息的潜力。U-Report 是一个移动赋权平台,将世界各地的年轻人与改变他们生活和影响决策的信息联系起来。之前对 U-Report 效果的研究强调了在及时性、低成本和高信息可信度方面的优势,但也强调了在数据表示方面需要改进的领域。EquityTool 开发了一种更简单的方法,根据来自大型家庭调查(如多指标类集调查 (MICS) 和人口与健康调查 (DHS))的较少问题,评估受访者的财富五分位数。
采用 EquityTool 方法评估孟加拉国 U-Reporter(即 U-Report 的注册参与者)的社会经济概况。RapidPro 流程收集调查回复,并使用 EquityTool 方法对 DHS 国家财富指数进行评分。这有助于将所有完成所有问题的 U-Reporter 分配到适当的财富五分位数。
有 19%的受访者完成了所有问题,受访者落入了所有 5 个财富五分位数,其中 79%在前两个五分位数,只有 21%在后三个五分位数,导致公平指数为 53/100,其中 100 完全符合孟加拉国的公平分配,1 是最不公平的。随后从定期和经常回复的 U-Reporter 中创建了一个 1828 名的公平随机抽样样本,用于未来的调查,该样本的公平指数为 98/100。
孟加拉国的 U-Report 确实覆盖了最贫穷的五分位数,而最初的招募偏向于较富裕的家庭。可以从所有五个财富五分位数中创建一个公平的随机受访者子样本,从而为未来的调查处理信息和数据。未来,来自代表性较差的五分位数的 U-Reporter 可能会得到激励,以招募更多的同行来提高公平性和代表性。在 COVID-19 时期,U-Report 与 EquityTool 结合使用,有可能提高众包数据的质量,用于统计分析。
