New York:  Historically, marriage was the surest route to financial security for women. Nowadays it's men who are increasingly getting the biggest economic boost from tying the knot, according to a new analysis of census data.

The changes, summarised in a Pew Research Centre report released on Tuesday, reflect the proliferation of working wives over the past 40 years — a period in which American women outpaced men in both education and earnings growth. A larger share of today's men, compared with their 1970 counterparts, are married to women whose education and income exceed their own, and a larger share of women are married to men with less education and income.

Gender role reversal

"From an economic perspective, these trends have contributed to a gender role reversal in the gains from marriage," wrote the report's authors, Richard Fry and D'Vera Cohn.

"In the past, when relatively few wives worked, marriage enhanced the economic status of women more than that of men. In recent decades, however, the economic gains associated with marriage have been greater for men."
