Hello there!
The interval on the X-Axis of the Histogram is inconsistent:
An Histogram is a graphic representation of the frequency of values. It should include all the data range on the x-axis. In this case, the x-Axis should include all intervals from 0 to 24 years, but in the graph the intervals "jump" from 10-14 to 20-24.
This inconsistency causes the difference between the two graphics because the two of them should be skewed to the left, according to the age distribution.
