Table 3. CASES OF SPECIFIED DISEASES: SELECTED CITIES FOR WEEK ENDED
MARCH 7, 1953-Continued
During the first 8 weeks of 1953 the number of deaths reported in 106 major cities exceeded the 3-year median for the corresponding week, 1950-52, by 11 to 25 percent. The two curves shown in the above chart are now close together – the difference between the current week and the median is only 2 percent. How ever, the curve for the 3-year median rose sharply in the first week of March, reflecting the experience of the last 3 years, when there was an increased incidence of influenza and pneumonia in the early spring.
The figures reported represent the number of death certificates received in the vital statistics offices during the week indicated, for deaths occurring in that city. Figures compiled in this way, by week of receipt, usually approximate closely the number of deaths occurring during the week. However, differences are to be expected because of variations in the interval
between death and receipt of the certificate.
While week-to-week changes in the total number of deaths reported for all major cities generally represent a change in mortality conditions, this may not be true for variations in weekly figures for each city. For example, in a city where 50 deaths are the weekly average, the number of deaths occurring in a week may be expected to vary by chance alone from 36 to 64 (d 12Vd, where
+ d represents the average number of deaths per week).
The number of deaths in cities of the same size may also differ because of variations in the age, race, and sex composition of their populations, and because some cities are hospital centers serving the surrounding areas. Changes from year to year in the number of deaths may be due in part to population increases or decreases,
