Health and Vital Statistics [PDF ebook] 

Originally published in 1968, this book was intended to help those in health and welfare services as well as those whose policy decisions are influenced by the movement of statistical indices of health, to understand the purpose, derivation and meaning of these indices. It teaches by presenting statistical problems as they are encountered in practice against the background of day-to-day administrative procedures to which they relate. Special attention is paid to practices in the USA and to considerations of international comparability.
