While it is true that the Negro population has increased according to our estimate about forty-five percent during the past two years, this expansion in nowise explains the disquieting increase in mortality. An examination of the table also reveals the character of this increase. Pneumonia cases have increased nearly two hundred percent; we also had a marked increase in acute bronchitis and meningitis, and almost twice as many deaths from heart disease.
