Married men are earning much more money, on average, than everyone else in America, according to a report from the Federal Reserve Bank of St. Louis. The St. Louis Fed plotted the income of workers with at least a high school diploma by age, gender and marital status and found that the wages of married men are higher than those of single men, married women and single women, and that's true at every age from 20 to 64. The difference is most pronounced at around age 45, when married men's earnings peak.

Guillaume Vandenbroucke, "Married Men Sit Atop the Wage Ladder," Federal Reserve Bank of St. Louis Economic Synopses, No. 24, 2018 This could just be a correlation: The data does "not imply that being married increases a man's wage," Guillaume Vandenbroucke, author of the report, notes. "It might be that men with higher wages are more likely to marry; therefore, the average married man earns a higher wage than the average single man." Also of note is that married and single women earn very similar wages. That's surprising, says Vandenbroucke, since married women are more likely to have children than single women, and that's "not consistent with the view that the gender wage gap results from women having children earlier in life and losing ground in human capital accumulation relative to men." In short, the gender wage gap is a complex topic, says Vandenbroucke: "Progress may come from asking different questions: not just why women earn less than men (although not compared with single men), but also why married men earn so much more than everyone else."

Here's the full breakdown of how much each group earns at every age. The numbers, provided by the St. Louis Fed, represent the wage and salary income of employed men and women with at least a high school diploma.
