  • Median, not average, so much better at showing this situation than mean but it’s still not great. I agree that it should be broken up, but the difficulty is how you define the grouping will have a significant impact on the results, especially in early and later years.

    I’d prefer median by age graphed by age. Average by any grouping will skew heavily if there is a lot of variance, and I absolutely expect there is in the US. A box-and-whisker plot could also be ideal here, but you still have the grouping problem.
