The absolute number of pedestrian deaths has been plateaued for 50 years despite the population size increasing: https://www.iihs.org/topics/fatality-statistics/detail/pedes...
60% of pedestrian deaths occur on high capacity urban roads. Kids in light residential neighborhoods don't deal with those roads. Tell your kids to stay away from heavily trafficked roads.
30% of pedestrian deaths involved a drunk pedestrian. Tell your children not to get drunk.
