Age and weight divisions
Some divisions allow "older but lighter" players who meet the age and weight requirements in parentheses.

Safety and brain health
In the 2010s, there has been much controversy about football and brain health, with a number of studies focusing not just on the occasional concussion, but also on the large number of sub-concussive hits. One game in particular in 2012 resulted in five concussions. In 2015, a family sued Pop Warner over the suicide of a former player who was later found to have chronic traumatic encephalopathy (CTE), claiming that the organization knew or should have known about the risk of head injuries. Several other lawsuits have been filed against Pop Warner for related cases.

In 2016, the Pop Warner league banned kickoffs in an attempt to reduce high-speed collisions that result in concussions.

A 2018 study found that tackle football before age 12 was correlated with earlier onset of symptoms of CTE, but not with symptom severity. There have also been advocates for flag football only before certain ages.
