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.

MORTALITY FROM TUBERCULOSIS, 1920.

The Bureau of the Census announces that nearly 100,000 deaths were due to tuberculosis in the death registration area of the United States in 1920, and 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 tuberculosis in the entire United States for 1920 was about 122,000, whereas for 1919 the number is estimated as 132,000, or 10,000 more than for 1920.

The trend of the tuberculosis death rate is downward. In the registration area of the 33 States which show rates for more than one year, 29 in the following table show their lowest rates for the year 1920. The tuberculosis death rate in the registration area in 1920 was 114.2 per 100,000 population, against 125.6 per 100,000 population for the year 1919.

To permit better interstate comparisons for the year 1920, adjusted rates based on the standard million population have been calculated. The highest adjusted tuberculosis rate for 1920 is 215.7 per 100.000 population for the State of Colorado, and the lowest is 40.8 per 100,000 population for the adjoining State of Utah. The high rate for Colorado is evidence not of unhealthfulness of climate, but of the attractiveness of the Colorado climate to persons afflicted with tuberculosis.

For the 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 tuberculosis rate for the white population is 137.6 per 100.000 for Kentucky, and the highest adjusted rate for the colored population is 354.9 per 100,000 population for the same State. The lowest adjusted tuberculosis rate for the white population is 54.2 for Mississippi, and the lowest for the colored population is 175.2 per 100.000 population for Florida.
