Total: ASM appears to be mostly extracting gemstones. Therefore it may be possible that ASM popultation has not increased since ILO-99. → 20,000
Min/max: As data is quite old, uncertainty is high. A range of +/-50% is believed reasonable. → 10,000 - 30,000
Female participation: no data. Working hypothesis 10% → 2,000
Gold: no data. Most likely almost none → 0
