How many people did't have health care in 2010?

Answer 1

Worldwide, well over a billion

Some people say health care when they really mean medical insurance. If some one pays his doctor himself there is no one to count him. He has health care but he may not have insurance. No one shows up at his doors step to ask do you have health care.

Even if they did, what if he said I feel fine I don't need a doctor. If I get sick I will go to a doctor then. Would you count him or not?

In some primitive cultures people who don't have modern medicine by western standards would still say that they had medical care. That is the medical that they are accustomed too. So I don't see how you can put an accurate number on it. Even if you did come up with some kind of a number what relevance would it have.
