As the U.S. population ages, the proportion of Americans who were alive when John F. Kennedy was assassinated is shrinking. Today, only 28.9 percent of all U.S. adults hold personal memories from the day he was shot, according to a Pew Research Center report.

However, of those who were 8 or older on the day of the event, the percentage who recall exactly where they were is much higher -- 95 percent, making the Kennedy assassination one of the most memorable moments in recent American history.

In comparison, only 81 percent of adult Americans can remember where they were when they heard that Osama Bin Laden had been killed -- an event that occurred just two years ago. The only recent event that is more memorable is 9/11.

According to the report, 74 percent of Americans said that Kennedy will be remembered as an outstanding or above-average president, the highest rating among the last 11 U.S. presidents.

The Pew Research Center asked U.S. residents who were 8 or older at the time of each event if they recalled exactly where they were at the time of the event. Here’s how many said “yes”:
