Growing up in some places — especially liberal ones — makes people less likely to marry, new data shows.

Places that make being married at age 26...
Less likely More likely
The place where you grow up doesn’t affect only your future income, as we wrote about last week. It also affects your odds of marrying, a large new data set shows.

The most striking geographical pattern on marriage, as with so many other issues today, is the partisan divide. Spending childhood nearly anywhere in blue America — especially liberal bastions like New York, San Francisco, Chicago, Boston and Washington — makes people about 10 percentage points less likely to marry relative to the rest of the country. And no place encourages marriage quite like the conservative Mountain West, especially the heavily Mormon areas of Utah, southern Idaho and parts of Colorado.

These conclusions — based on an Upshot analysis of data compiled by a team of Harvard economists studying upward mobility, housing and tax policy — are not simply observations about correlation. The economists instead believe that they have identified a causal role that geography plays in people’s lives. The data, which covers more than five million people who moved as children in the 1980s and 1990s, suggests that children who move from, say, Idaho to Chicago really do become less likely to marry, even if the numbers can’t explain exactly why these patterns exist.

We have also written about other findings from the study, focusing on upward mobility, and we encourage you to explore them when you’re done here.
