From NPR, a list of 5 common parental worries that are extremely unlikely, and the top five risks for kids: the gap between the two is the source of much anguish, bad policy, and danger:

Based on surveys Barnes collected, the top five worries of parents are, in order:

1. Kidnapping
2. School snipers
3. Terrorists
4. Dangerous strangers
5. Drugs

But how do children really get hurt or killed?
1. Car accidents
2. Homicide (usually committed by a person who knows the child, not a stranger)
3. Abuse
4. Suicide
5. Drowning

I don’t see abducted by aliens on there anywhere.
