This map shows the ability of the health service of each territory to provide good basic health care to a number of people. The health service quality score for 1997 was applied to the population. The world average score for health service quality was 72 out of 100. This means that the equivalent of 4.5 billion people had access to good basic health care.
The populations with the poorest health care provision live in Sierra Leone and the Central African Republic. The Sierra Leonean health system scored 36 out of 100 - that is half the world average score. Note that only the most basic care is measured here.
