I wonder if there's any data on this from countries that did a lot of contact tracing.

On the one hand, I thought it strange a year ago when some authorities based policy on the assumption that kids didn't spread it. On the other hand if kids are mostly asymptomatic it would make sense that they don't spread it as much. I know that private schools in my area were running normal classes, en masse nothing bad seemed to happen.

Hard data would be nice to see, if it's out there.

Also, old people can be vaccinated now, so fears over children spreading it to vulnerable population is becoming a moot point.
