Female representation in parliaments by country

The share of seats held by women in national parliaments is one of my preferred proxies for gender equality. It's easy to quantify and speaks directly to the relative impact of women in our societies. Our world is still a very patriarchal place, but in the Middle East women are particularly under-represented. New Zealand—the first self-governing country to grant the vote to all adult women—is doing reasonably well, but still has a long way to go.
