Nonetheless, more than one out of every ten of these relationships ends in marriage: According to the most current Census Bureau data, older women marry younger men in around 12% of all marriages. That's about the same rate as five years ago. Older men marry much younger women. In fact, according to the Census data, older men are almost three times as likely as older women to be married. This ratio isn't very different from that seen in other countries where there is no age discrimination in marriage laws. In terms of ages, we can see from the table that young men tend to marry young women, while old men tend to marry old women. However, it's important to remember that men are generally marrying within their own age group, so the average man is marrying a woman about his age. Women, on the other hand, are usually marrying up or down (i.e., younger or older) than themselves. So, the average woman is marrying a man about seven years her senior. Looking at this number alone, it would seem like young men are doing most of the marrying. But this is because they make up about 70% of the population.
