12.1% of men 18 years and over are in fair or poor health.
What is the meaning of "in fair health" here?
For me "in fair health" sounds like "healthy".
But it makes no sense that healthy+unhealthy people would make only 12.1% of the population.
So, does "in fair health" mean "unhealthy but not as unhealthy as poor health"?
