Diphtheria-Annual case rates per 1,000 population, January to October, 1921 and 1920,
and medians for the years 1913 to 1920, inclusive-Continued.
The accompanying table shows the number of reported cases of warlet fever per 1,000 population by quarters, from January to June, and by months, from July to October, 1921, compared with the wame periods during 1920, and the medians for 1913 to 1920, inclusive.
The median was ascertained by arraying the figures so that the greatest number was first, the next smaller number was second, and so on to the smallest number, which was placed last. The middle number of the array was then selected as the median. Data were not available for all the States for the full eight years. As many years as possible were included for each State, but no year farlier than 1913 was used. The first column shows the number of years for which figures were obtained for each State.
The estimated populations on which the rates were computed are as follows:

MORTALITY FROM ORGANIC DISEASES OF THE HEART, 1920.
The Bureau of the Census, Department of Commerce, states that 124,000 deaths were due to organic diseases of the heart in the death registration area of the United States in 1920, and that if the rest of the United States had as many deaths from this cause in proportion to the population, the total number of deaths from organic diseases of the heart in the entire United States for 1920 was 151,000, whereas for 1919 the number is estimated at 138,000, or 13.000 less than for 1920.
The trend of the death rate from organic diseases of the heart is upward, the lowest recorded rate for the registration area having been 111.2 per 100,000 population for the year 1900, and the highest rate 153.8 per 100,000 population for the year 1917. For 1920 the rate was 141.9 as against 131 per 100,000 population for 1919.
** Adjusted” rates based on the standard million population have been calculated in order to permit better interstate comparisons for the year 1920. The highest adjusted rate from organic diseases of the heart for 1920 is 180.8 per 100,000 for the State of New York, and the lowest is 87.3 for Kentucky.
For States in which at least 10 per cent of the population was colored, adjusted rates have been calculated separately for the white and colored populations. In this group of States the highest adjusted rate for the white population is 179.8 per 100,000 for New York, and the highest rate for the colored population is 248.3 per 100,000 for the same State; the lowest adjusted rate for the white population is 75 for Mississippi and the lowest for the colored population is 112 for Florida.
