Who goes there?

Nearly 30% of Americans admit they don’t know most of their neighbor’s first names. But at least 90% have smiled or spoken to their neighbors—at least once—according to a new survey of more than 1,000 Americans released by Safehome.org, a home security systems review resource.

53% of those surveyed said they’d introduced themselves when a new neighbor was moving in, but they won’t likely become best buddies. Only a fraction of Americans (34%) say they’ve been in their neighbor’s home or vice versa, and only 16% have hung out with neighbors outside of the neighborhood.

Baby boomers tend to be the most neighborly generation, according to the survey. 76% of boomers said they’ve spoke to their next-door neighbor frequently, while only 36% of millennials have said they’ve done the same.
