Tis is the article: The millennial success sequence: Marriage, kids, and the ‘success sequence’ among young adults. These are the opening points:

Millennials are much more likely to flourish financially if they follow the “success sequence”—getting at least a high school degree, working full-time, and marrying before having any children, in that order.

While 55 percent of 28- to 34-year-old millennial parents had their first child before marriage, the vast majority of millennials who married before having any children are now steering clear of poverty and appear to be headed toward realizing the American dream. Additionally, 95 percent of millennials who married first are not poor, compared to 72 percent who had children first.

Even millennials from low-income families are more likely to flourish if they married before having children: 71 percent who married before having children made it into the middle or higher end of the income distribution by the time they are age 28–34. By comparison, only 41 percent of millennials from lower-income families who had children first made it into the middle or higher end of the distribution when they reached ages 28–34.

Boring, but what can you do?
