PUBLIC HEALTH, NURSING AND MEDICAL SOCIAL WORK

Editors: MYRON E. WEGMAN, M.D..

THERE are reprinted below certain charts from two publications of the National Office of Vital Statistics in the U. S. Public Health Service, FSA, "Monthly Vital Statistics Index" and "Current Mortality Analysis."

From the former are the trends in birth rate and infant mortality rate. These are based on provisional data and may be subject to slight change when final figures are available. Birth rates are per 1000 estimated population excluding armed forces overseas; infant mortality rates are per 1000 live births, adjusted for the changing number of births. Attention is called to the persisting high birth rate and the gratifying continuing fall in infant mortality.

The variation charts (p. 703), from Current Mortality Analysis, are printed to indicate the present day seasonal changes in these diseases as well as to show the extent of the differences which may usually be expected from one year to the next. Although the charts are based on a 10% sample it may be expected that in general they come close to describing the actual situation in the country at large.

It should be noted that the data represent death rates as reported on death certificates and therefore reflect only indirectly the prevalence of the disease.

The three components of the variation charts are: (1) the dots which represent the values of the monthly death rates observed from the sample, (2) the central line which represents the expected death rate for a given cause of death in a particular area and (3) the shaded band above and below the central line.
