How many women reach menopause each day?

As a sensual researcher I often search out simple ways to answer questions about menopause that I can easily pass on to others.

Yup, that's my tech-geek side coming out again chewing on numbers for fun. Basically I wanted to know how many of us are there? I ran across this infographic that put a few things in perspective.
