100 Women: Meet America's new breadwinners

In the US a profound social change is happening, as an increasing number of families rely on mothers to make the most money.

In fact, more than 40% of American households with children now have so-called "breadwinner moms" - up from one in 10 back in 1960.

As part of the BBC's 100 Women series, Katty Kay travelled to Richmond, Virginia to see the impact it's having on women, families and the economy.

Produced by Ted Metzger, filmed by Peter Murtaugh and edited by Bill McKenna.
