I grew up in Karachi, and this "absence of women" is an alien concept to me. It is common for competing stores selling nearly the same product to be next to each other, organically forming a whole street market with hundreds of stores specializing in products of one theme. There's an electronics parts market, an LED bulbs market, a used books market, a glass market, a kitchen-ware market, a used clothing market, the pirated software media market. This makes the markets loosely gender-segregated - auto parts markets don't attract as many Pakistani women as the dresses markets do.
