This represents an average annual rate of 77 per hundred thousand and places pneumonia fifth as a cause of death. If it should be combined with influenza, however, the average annual rate would be 100, thus placing this group near cancer, close to second place.
On the basis of experience in the last six years, chance of a given death being due to pneumonia is approximately one in fourteen. Pneumonia mortality is highest among the young and the very old, higher among males than among females, and higher among Negroes than among white persons. Excessive pneumonia mortality rates occur in certain industries.
