It's interesting to consider why it's ~1000 and not some other number like 100 or 10,000. It's probably a combination of irreducible information complexity (a system for adding/removing people, processing premiums, investigating claims, paying providers probably costs too much for 100 people) and statistical risk (100 people are chaotic, whereas 1000 people are relatively smooth).
