"Note that annoyingly the scale chosen for the four pyramids are not the same. Despite its appearance, the Asian pyramid is quite similar to the one for whites."

Am I missing something? The four age pyramids all appear to have exactly the same scales, and the largest categories ( for males) are 30-34 for asians and 44-49 for whites.


Rosie: Take a look at the range of the horizontal axes! The one for whites goes out to 6 on each side but the one for Asians only goes out to 5. So to compare them, we have to mentally squeeze the Asian pyramid a little, and I think doing that will make the Asian one similar (not identical) to the white one.

Ahhh. I was looking at the vertical axes but not the horizontal axes! Thanks.
