In Stage 1, birth, death, and infant mortality rates are all high, while life expectancy is short. Crude birth rates are usually expressed as the number of live births per year per 1000 of the population. Demographic concepts and practical strategies important in the interpretation of population statistics are also discussed. United Nations (1968). The Multilingual Demographic Dictionary, however, differentiates between various aspects of demography by defining separately demographic statistics, economic demography and social demography; the latter two imply the “study of relations between demographic phenomena on the one hand and economic and :social phenomena on the other”.

Fertility is distinguished from fecundity, which means the number of children women are able to have in biological, terms. CONCEPT & SCOPE • Demography is the branch of social science, which deals with the study of size, structure and distribution of populations, along with the spatial and temporal changes in them in response to birth, migration, ageing and death. Census data is used by the federal government to determine how many members of the House of Representatives each state has, and it can impact how federal funds are spent. They are called crude rates because of their very general character. births deaths migrations.

Because of it, growth rate of population is also different. 5. A higher percentage of the working-age population can raise the economic output in a country as well as increase its per capita income. Demographic analysis can relate to whole societies or to smaller groups defined by criteria such as education, religion, or ethnicity. While there may be families in which a woman bears twenty or more children, fertility rates in practice are always much lower than fecundity, because social and cultural factors limit breeding. Keywords Population Change Total Fertility Rate American Community Survey Crude Death Rate Crude Birth Rate Demography is widely used for various purposes and can encompass small, targeted populations or mass populations. The infant mortality rate is the number of babies that die before the age of one per 1000 live-births in any year. It encompasses the study of the size, structure and distribution of populations, and how populations change over time due to births, deaths, migration, and aging. Part 1 Introduction: the characteristics of applied demography.
