Based on data from the How Couples Meet and Stay Together survey, the chart shows that people typically wait longer to get married and live together sooner now than they did several decades ago. We saw this in the median timeline comparison.

However, in this view, you can better see the variation and extremes. You can see the people who married within the first few months after meeting. There are the people who married five decades after first meeting. I think there's a romantic comedy script hidden somewhere in there.

Notes

The data comes from the 2017 release of the How Couples Meet and Stay Together survey, administered by Michael J. Rosenfeld, Reuben J. Thomas, and Sonia Hausen.
