Eight-in-ten Americans say they don’t generally answer their cellphone when an unknown number calls, according to newly released findings from a Pew Research Center web survey in July. Only 19% of U.S. adults say they generally answer the phone for an unknown number. The majority of Americans say their general practice is to not answer their phone when an incoming call is from an unknown number, but they check a voicemail if one is left. The survey also finds that Americans ages 18 to 29 are more likely to take calls from unknown numbers than those in older age groups. In addition, Hispanic and Black adults are more likely than White adults to say they generally pick up for a number they don’t recognize.
