Unfortunately you'll have to count manually: there are 20 per page.
However, while these stats are nice, you should really be looking at the expertise section in reputation. This lists how many points you have earned in each space (forum) for answering questions, providing helpful answers, etc. No, it's not as detailed as what you seek but it does provide a global answer to how you're doing. Reputation > Expertise > Scroll or filler for a space.
