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.
