I can speak to that. It depends on what outcome you're looking at.
For some children, the home environment they were captured in, for lack of a better phrase, may have improved. They may have received one-on-one, undivided attention from their parents, who were able to stay home and take care of their needs. Some things may have increased. For some children, their needs might have improved being in the home environment through the pandemic and home-schooling.
When we think of the families with the least amount of resources who couldn't provide that and were struggling, trying to do their job and to find adequate care and education for their children, those children would have suffered the most during the pandemic and perhaps have been left behind.
I think it depends on the circumstances and what outcomes you're specifically looking at then saying what went up and what went down.
