Interactive · Agent-based model
Imagine two different worlds. The workers, their preferences, and the occupations are identical — the only difference is whether workplaces within each occupation are gender-mixed or gender-sorted. Below two simulated labour markets run side by side. Watch how occupational segregation changes. That gap is the shielding effect.
Within each occupation, workplaces are gender-mixed (Dʷ ≈ 0.1)
Within each occupation, workplaces are gender-sorted (Dʷ ≈ 0.9)
Dissimilarity index of the two worlds. The shaded band is the shielding effect.
Workers tend to prefer colleagues of their own gender. This is what is called gender homophily. When someone becomes a minority in their occupation, that pressure can push them to leave — which makes the occupation even more lopsided, and so on.
But people don't experience an occupation in the abstract: they experience their own workplace. If that workplace still has plenty of same-gender colleagues, the worker is shielded from the wider imbalance at the occupational level and stays put.
Counter-intuitively, this means workplace gender-sorting can dampen occupational segregation. Sorted workplaces give minority workers local pockets where their preferences are met, so they don't exit the occupation entirely.
The effect is structurally asymmetric: it works mainly by keeping occupational minorities in place, with little offsetting effect on the majority — so it doesn't cancel out in the aggregate.
