First published in 1968, Demographic Analysis was written to provide a comprehensive account of demographic methods for those with a need to understand population movements. The book provides an introduction to some of the key tools used by demographers and the principal sources of population data. Beginning with an overview of the scope, content and use of the population census, it then examines methods for measuring births, deaths, and migration before setting out the methodology for determining the contributions of these elements to population change and estimating past or future changes. The book also explores sickness as a population characteristic and a way of better understanding mortality variations.
