Most Homeowners Are Aged 55 or Older

The 51 percent majority of the nation's homeowners are aged 55 or older, according to the Census Bureau, up from 43 percent in 2006... 

Homeowners by age in 2014 (and percent change since 2006)
Total owners: 74,427,000 (-2.2%)
Under age 35:  8,943,000 (-16.8%)
Aged 35 to 44: 11,808,000 (-22.9%)
Aged 45 to 54: 15,683,000 (-11.0%)
Aged 55 to 64: 16,383,000 (14.4%)
Aged 65-plus: 21,609,000 (19.2%)

Behind the increase in the number of homeowners aged 55 or older is the aging of the baby-boom generation. Behind the decline in the number of homeowners under age 35 is the plunging homeownership rate among young adults.
