I need help understanding how population pyramids work. I know that the age groups go up and down, and that the gender and how many males/females is at the bottom. How do i figure out what stage they are and where i would place them on the demographic transition? Im comparing Germany 2007 and Germany 2025.

Thanks for the help!

This site may help you.

I'm sure Germany's trend is similar to that of Sweden and the United Kingdom.
