Excerpt from Facts About Tuberculosis: Twenty-One Diagrams With Brief Descriptive TextIn the selection of facts about tuberculosis which are here represented we have used figures for the entire registration area for the background, and local figures for New York City* and some other places for details not available for the larger area, figures for 1913 or 1914 when we do not need death-rates, or when we are concerned only with the crude rate, but figures for 1910 for rates by sex, age, and nationality, figures for cer tain selected localities in considering the decrease that has taken place. Rates per population are used instead of per thousand, in order to make com parisons easier, by avoiding decimal fractions.As far as possible the statistics from which the dia grams are made are printed on the diagrams. The original figures are to be found, except when other sources are mentioned, in the annual Mortality Reports of the federal Census Bureau or in the annual reports of the Department of Health of New York City. No attempt has been made to explain the facts presented, since any adequate discussion of them would fill a book.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
