  1. Source: Data are from South African Labour Force Surveys (LFS) conducted by Statistics South Africa (15 waves September 2000 to September 2007).
  2. Notes: Dependent variable is a dummy variable equal to 1 if the individual is employed in the respective sector and equal to 0 otherwise. The sample includes individuals of working age who are employed or seeking work, and who have completed no more than 12 years of schooling (Matric). Robust standard errors clustered by district council are shown in parentheses.***p < 0.01, ** p < 0.05, * p < 0.1. Individual controls include controls for race, years of schooling and gender. The wage gap measures the proportional increase in the real wages of workers in district council i at time t-1 necessary to meet the minimum wage at time t. The F-statistic refers to the test for the null hypothesis that the regression coefficients are equal to zero, which is rejected at the 1, 5 and 10 percent levels.
