I realize the harm factor is at play, but it's not the sole cause.
US Population 0-17 was 74.1m in 2010, it is 74.1m today. (US Census data). This is a record high.
While the birth rate per female has gone down, we added 25m more females in the last two decades, majority via immigration. That is somewhat normal for the last 100 years. Even with the declining birth rate, the sheer number of females of childbearing age is projected to increase the number of children to 76.3 m.
So when comparing 2010 data to today, you should see the same raw numbers participating, since there are exactly the same number of children as then.
I agree culture factors beyond fear of injury are at work. Primarily the increase in urban density and the decline in suburban youth populations (Santa Clara County suburbs are very much bucking that trend, but it probably has more to do with the sheer number of people moving in -- we literally are short of facilities and have to ration youth participation in many sports; but Pop Warner football is not one of then, it has been shrinking every year).
I think another culture factor is the increased investment parents have in children due to smaller family sizes and greater competition for high reward jobs beginning with increased competition in middle school for grades and scores. Since the majority of people now live in higher density major cities and their suburbs, the competition has become more intense, more like Europe or Asia than the US just a few decades ago.
Where football is still popular, and sport in general, is where academic achievement is valued the least, which is among African American communities and in the Southeastern part of the US, and also a good chunk of the Midwest. Football has declined the most rapidly where Academics are valued the most, which is the Eastern Corridor, especially as you get north into New England, and along the Pacific Coast.
But since to absolute numbers of youth population continue to slowly grow, a decline in the number playing sports, especially football, cannot be attributed to fewer children.
