However, women in skill cells with a higher share of foreign-bom women do appear to earn higher incomes at the national level. This could be due to the increased participation of native-born women in the labour market due to immigrant women taking over childcare and household services (Furtado, 2015, Peri, 2014, see also Chapters 3 and 5). Furthermore, a significant and positive regional effect is observed when considering the impact on real wages of South African-bom workers - a one percentage point increase in the share of immigrants is associated with an almost 1% increase in the real wages of the native-born workers (Table 4.A2.1). By 2011, foreign-bom employment in agriculture and even more so in industry (including mining) decreased, and more foreign-bom workers became employed in the growing service sectors of the economy.
