Incidence attributable to recent transmission in mining areas

	From recent transmission in mining areas (col. 1)	From recent transmission in all areas (col. 2)	Fraction of all incidence due to recent transmission that is attributable to mining areas (col. 1/col. 2)
Incidence among mining residents	58.2% (57.8%, 58.9%)	63.0% (58.5%, 67.7%)	92.5% (92.1%, 92.9%)
Incidence among peri-mining residents	4.8% (4.3%, 5.2%)	39.3% (35.4%, 43.2%)	11.4% (10.2%, 12.7%)
Incidence among labor-sending residents	4.9% (4.4%, 5.2%)	39.5% (35.9%, 43.2%)	11.6% (10.7%, 12.6%)
Incidence among other SA residents	0.0% (−0.2%, 0.3%)	36.3% (33.7%, 38.9%)	−0.4% (−1.3%, 0.4%)
Incidence among all residents	2.4% (1.4%, 3.3%)	37.4% (35.2%, 40.0%)	3.7% (3.0%, 4.4%)

Using the individual-based model, transmission ceased in mines (column 1) or in the entire population (column 2) beginning in year 2012, and differences in incidence were measured between years 2014 and 2019. Mean and 95% CI are shown using parameters with highest likelihood from model calibration
