Look at the spread from #1 to #2. At young ages, the difference is pretty high, suggesting that young kids falling from things is common. In the middle age ranges, #1 and #2 are pretty close, suggesting that falling isn’t that different (from a statistical frequency POV) from the #2 option.
But then look at the split at the older age groups. Falling is by and far the biggest cause. By a ton. Starting at 45, the split just keeps growing. And these numbers are higher in general than any other age group, so they skew the “all ages” numbers by a lot.
So, while it is a major cause for all age groups, the effect size is very age related.
I would suspect that "unintentional fall" also covers falling over (like, the kind of fall that would happen if you tripped over a garden hose), not just falling off something. The former is the most common cause of emergency visits among the older people I know.
I figured for all ages it would also encompass falling off something. A chair, bed, etc… one type is more predominant for the younger ages (falling from something), the other is likely more predominant for the older ages (falling down, tripping, stairs, etc).
Falls hit 50% fatal above a twelve foot drop. Remember kids gravity is an accelerative force. It isn't a static force. You fall faster and faster every second you fall.
