Measuring marriage and money

Basically, the richer you are the more likely you are to marry, according to the Brookings Institute's Hamilton Project. Actually, overall marriage rates have fallen over the last 50 years, but the decline is steeper among low-income Americans. From Economix:

Forty years ago, about nine of 10 American men between the ages of 30 and 50 were married, and the most highly paid men were just slightly more likely to wed than those paid least. Since then, earnings for men in the top tenth of the income distribution have risen and their marriage rates have fallen slightly, from 95 percent in 1970 to 83 percent today. For men further down the income ladder, however, both earnings and their chances of connubial bliss have plummeted.
