By the numbers: The share of Americans who moved in the past year is about half of the number in the 1950s, when about one-fifth of the population moved each year. That number is now 9.8%, the first time it’s dipped below 10%.

Only 20% of people aged 20-24 moved this past year, down from 29% in the 2005-06 year.

Of those in their late 60s, only 4% moved in the past year.

19.7% of renter households (who tend to be more mobile than homeowners) moved, down from 30.2% in 2005-06.
