Young Americans are staying close to home

By the numbers: By age 26, 80% of young adults live fewer than 100 miles from where they grew up.

• 90% live fewer than 500 miles away.

And young adults' mobility breaks down along racial and socioeconomic lines.

• Black and Hispanic people live closer to their hometowns than other groups, per the study.
• And "distances traveled rise rapidly at the top of the income distribution, increasing to an average of 325 miles for those born to families in the top 1%."

The context: Pew recently found that multigenerational living is rising dramatically among young Americans, in part as a way to cope with skyrocketing housing and schooling costs.

• Geographic mobility is down broadly across groups too.

The takeaway: Those who can afford to live far from home have an easier time accessing opportunities in far-flung, economically healthier cities. As the new study puts it: "Young adults from the least affluent families are more exposed to the strength of labor markets in their hometown and less exposed to the strength of more distant labor markets."
