The ballpark figure that I use is that HOT (the organization) + missing 
maps activity is about 5-15% of total activity. Humanitarian mapping is 
a bit broader, but probably wouldn't change the numbers much.

Exact figures depend on what you define activity as, but 5-15% is valid for

- Active mappers who have at least 1 HOT changeset
- Total mappers who have at least 1 HOT changeset
- Number of changesets
- New signups who have a HOT changeset

Unless a big focus of your presentation is on activity and how to 
measure it, I'd just stick with 10% as being approximately right.
