背景资料：贫民窟，特别是发展中国家城市中的贫民窟，贫困和不利的环境条件集中，这是公共卫生政策倡议和其他部门相关方案日益关注的一个重要问题。然而，关于贫民窟生活对人类健康的人口影响的资料很少。这份手稿描述了2005年贫民窟普查和绘图（CMS），该普查使用地理信息系统（GIS）工具和数字卫星图像，并结合更传统的实地工作方法，以获得有关孟加拉国六个主要城市所有贫民窟生活的详细、最新和新信息结果：CMS发现，孟加拉国的贫民窟非常多样化：在人口规模、密度、居住在贫民窟的城市人口百分比和卫生条件方面，城市内部和城市之间存在很大差异。调查结果还表明，共同的信念，贫民窟可能是过时的，值得注意的是，土地权不安全被发现是一个问题，只有一小部分的slums.Conclusion：在2005年孟加拉国CMS使用的方法提供了一个有用的方法来绘制贫民窟，可以适用于其他低收入社会的城市地区。这一方法可能会成为一个日益重要的分析工具，为政策提供信息，因为预计发展中国家的城市在未来几年内将继续增加其在全球总人口中的份额，而同期贫民窟人口的规模将增加一倍以上。
Background: The concentration of poverty and adverse environmental circumstances within slums, particularly those in the cities of developing countries, are an increasingly important concern for both public health policy initiatives and related programs in other sectors. However, there is a dearth of information on the population-level implications of slum life for human health. This manuscript describes the 2005 Census and Mapping of Slums (CMS), which used geographic information systems (GIS) tools and digital satellite imagery combined with more traditional fieldwork methodologies, to obtain detailed, up-to-date and new information about slum life in all slums of six major cities in Bangladesh (including Dhaka).Results: The CMS found that Bangladeshi slums are very diverse: there are wide intra- and intercity variations in population size, density, the percent of urban populations living in slums, and sanitation conditions. Findings also show that common beliefs about slums may be outdated; of note, tenure insecurity was found to be an issue in only a small minority of slums.Conclusion: The methodology used in the 2005 Bangladesh CMS provides a useful approach to mapping slums that could be applied to urban areas in other low income societies. This methodology may become an increasingly important analytic tool to inform policy, as cities in developing countries are forecasted to continue increasing their share of total global population in the coming years, with slum populations more than doubling in size during the same period.
