Your participation is being used to motivate the general public - not as part of the full survey. If you don't know the precise numbers, we would be happy with an estimate.

We are interested in the number of people you meet face-to-face in one day (i.e. only within 10 feet/3m, don’t include audiences etc.).

We will make it clear that these numbers represent a single snapshot, not necessarily a typical day for you.

We would be happy to discuss any of these details with you by phone, email or in person, and will always try to accommodate your wishes. Contact Professor Matt Keeling.
