The study lists the top 15 large metro areas — those with 1 million or more residents — with the most female breadwinners. The only metro area in the country that beats Hartford-West Hartford-East Hartford is in New York — Buffalo-Cheektowaga-Niagara Falls to be exact. There, 33.6% of heterosexual married-couple households have female breadwinners. But the female breadwinners’ median earnings is $16,000 less than the Hartford area’s, at just $70,000.
