Percentage of Households with no Rubbish Disposal

The data was derived from the 2011 national census. The number of households with no rubbish disposal were obtained from the census small area layer data. A 500m grid was used to map the dwelling frame distribution for South Africa. The resulting dataset was then intersected with the small area layer for the purpose of esmating the area percentages of dwellings within each grid cell. The area percentages for the grid cells were multiplied with the corresponding census count for each small area in order to map households with no rubbish disposal.

本数据集源于2011年全国人口普查数据。无垃圾处理设施的家庭户数，通过普查小区域图层数据提取获得。研究以500米网格对南非的住宅单元分布开展空间制图，随后将生成的数据集与小区域图层进行空间叠加分析，以估算每个网格单元内住宅单元的面积占比。将各网格单元的面积占比与对应小区域的普查户数相乘，最终完成无垃圾处理设施家庭的空间制图。
