The uncertain future surrounding Social Security has many concerned about the number of benefits they will receive once they retire, according to a new poll.

In the survey which polled more than 1,200 retirees, about 65% said they greatly rely on Social Security, while 21% said they rely on it somewhat. When AARP conducted that same study in 2005, half of those surveyed said they relied heavily on their checks.
