Demography is a broad [?] science discipline concerned with the study of human [?]. Demographers deal with the collection, presentation and [?] of data relating to the basic life-cycle events and experiences of people: birth, marriage, divorce, household and family formation, [?], ageing, migration and death. The discipline emphasises empirical investigation of population processes, including the [?] and [?] of these processes and the study of their determinants and consequences. Practitioners [?] draw on related [?] areas - sociology, economics, political science, anthropology, psychology, public health and ecology - to illuminate their analyses. They may explore biological and biosocial aspects of [?] and mortality in areas such as [?] health and epidemiology.

The field of demography is also [?] with the broader nature of social and economic change, and with the impact of demographic change on the [?] environment. The concepts of life tables, event histories, population momentum and stable populations that have [?] from demography have made significant contributions to an [?] of social change. The demographic literature is also rich in coverage of broad topical studies of human resources; [?] and morbidity; family systems and family structure; the role of women; the value of children; and the social, [?] and institutional context of demographic change.
