Last year, MONEY conducted an exclusive survey on men, women, and money. The results captured sweeping changes in the way husbands and wives manage their finances and the impact of money on a marriage, particularly as wives bring home more of the bacon. This year, we dug down into generational differences: Our latest MONEY poll compares the perceptions and behaviors of some 500 millennials and 500 baby boomers when it comes to their relationships and money. The results reveal distinct differences in their approaches to financial matters. But one theme crosses generations: Couples who are in sync on issues like saving and budgeting feel more financially secure, argue less about money—and have hotter sex lives.
