Few Americans know their neighbors, according to a new survey from Rocket Mortgage. The survey reveals just 30 percent of Americans know their neighbors beyond a casual level. Despite this, nearly 80 percent of respondents said strong neighborhoods improve their quality of life.The report notes that 50 years ago, neighborhoods were the center of belonging, culture and identity, with 80 percent of Americans saying they were once places where people naturally connected. The new data shows that dynamic has dramatically shifted, with hesitation emerging as the most prominent barrier to connection, the report stated. Four in 10 say knocking on a neighbor's door feels too bold, while 22 percent say they feel awkward making the first move.Nearly 29 percent of Americans say they sometimes avoid socializing with neighbors, often because they're in a hurry or preoccupied. More than half of respondents say small, repeated moments such as a quick hello, a short conversation or returning a misdelivered package do more to build relationships than planned gatherings.
