and the summary

While the fear of being kidnapped may persist for one’s entire life, in 2020 the number of missing persons under the age of 21 was much higher than those 21 and over, with 209,375 females under 21 reported missing, and 59,369 females over the age of 21 reported missing.

If you total them up you will find approx 5100 more males missing but they aren't even mentioned.
