And just what percentage of kids who played outside in the late '80s/early '90s do you think were seriously injured or abducted?

Because whatever you think it is, that's probably much too high. Because it almost never happened. There were a very few highly-publicized cases of children disappearing (eg, JonBenet Ramsey, or in my area Sarah Ann Wood), but a) those were always incredibly rare, and b) such occurrences have been getting steadily rarer for many decades.
