Married women 45 and younger are twice as likely as older married women to make the financial decisions in their families, according to a new report from Merrill Lynch Wealth Management.

The report surveyed 4,000 women of all ages. It found that more women, regardless of martial status, are taking control of their money: 75% of women under 45 reported managing their money on their own, compared to 50% of women over 55.
