Its quite misleading
It's not though. These are based on missing person reports. Just because they are found doesn't mean they aren't missing. If a child is missing for two weeks, and is found safe, does that mean they weren't missing? What's the difference between two weeks and two hours is a parent is missing their child? Just because you're a remarkably apathetic individual who doesn'tcare enough to how statistics of missing children works doesn't change how the statistics of missing children work.
