The gap between the rich and poor is at its widest in nearly half a century, and nearly one in five people live in poverty.

By the numbers: Rents in Hong Kong are often higher than New York, London or San Francisco for apartments half the size. And pay hasn’t kept up; the minimum wage is currently $4.82 — far below the $7 estimated to be a “living” wage.

In opposition: Pro-democracy activists believe that direct elections would give them a greater say in Hong Kong’s crucial economic decisions, while some pro-Beijing officials see greater gains from more integration with the mainland.

Violence: Dozens of people were wounded at a train station in the territory late Sunday night as men with sticks and metal bars apparently targeted demonstrators.
