"84 percent of Americans say having a guarantee of monthly income for the rest of their life is important to them. Nearly half (48 percent, up from 34 percent in 2014) say that having guaranteed income to cover living costs should be the primary goal for their retirement plan.... But ... only 14 percent have actually purchased an annuity, which is the only way to ensure income that retirees can't outlive. Furthermore, many Americans (44 percent) are unsure if their current retirement plan even offers them the option of receiving a monthly paycheck in retirement."
