Percentage of the Workforce Employed in the Informal Sector

The data was derived from the 2011 national census. The number of individuals employed in the informal sector 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 the workforce employed in the informal sector.

本数据集源自2011年全国人口普查。非正规部门（informal sector）就业人员的数量提取自该普查的小区域图层数据。研究采用500米网格绘制南非的住宅单元分布图谱。随后将生成的数据集与小区域图层进行空间相交分析，以估算每个网格单元内住宅的面积占比。将各网格单元的面积占比与对应小区域的普查人口计数相乘，最终绘制出非正规部门就业劳动力的空间分布图谱。
