"Demography is the statistical study of populations, especially human beings."
The study of population dynamics, including growth, distribution, and migration.
Population size: The total number of individuals in a population.
Population distribution: The pattern of how individuals are distributed across a geographic area.
Population density: The number of individuals per unit of area or volume.
Population growth: The change in population size over time, due to births, deaths, immigration, and emigration.
Fertility: The ability of individuals or couples to have children.
Mortality: The incidence of death in a population.
Life expectancy: The average number of years a person is expected to live based on current mortality rates.
Age structure: The distribution of individuals across different age groups within a population.
Population pyramids: Graphical representations of age and sex structures of a population.
Migration: The movement of people from one place to another, including immigration and emigration.
Population policies: Interventions by governments or other organizations aimed to influencing population size, distribution, or characteristics.
Demographic transition theory: A model that describes how populations change over time from high birth and death rates to low birth and death rates.
Population ecology: The study of the interactions between a population and its environment, including resource use, competition, and predation.
Urbanization: The process by which populations become concentrated in urban areas.
Rural-urban migration: The movement of people from rural to urban areas.
"Demographic analysis examines and measures the dimensions and dynamics of populations."
"It can cover whole societies or groups defined by criteria such as education, nationality, religion, and ethnicity."
"Educational institutions usually treat demography as a field of sociology."
"These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration."
"Demographic analysis estimates are often considered a reliable standard for judging the accuracy of the census information gathered at any time."
"In the labor force, demographic analysis is used to estimate sizes and flows of populations of workers."
"In population ecology, the focus is on the birth, death, migration, and immigration of individuals in a population of living organisms."
"For example, it is often used in business plans, to describe the population connected to the geographic location of the business."
"Demographic analysis is usually abbreviated as DA."
"Patient demographics form the core of the data for any medical institution, such as patient and emergency contact information and patient medical record data."
"Patient demographics include: date of birth, gender, date of death, postal code, ethnicity, blood type, emergency contact information, family doctor, insurance provider data, allergies, major diagnoses, and major medical history."
"Formal demography limits its object of study to the measurement of population processes, while the broader field of social demography or population studies also analyses the relationships between economic, social, institutional, cultural, and biological processes influencing a population."
"Demography (from Ancient Greek δῆμος (dêmos) 'people, society', and -γραφία (-graphía) 'writing, drawing, description')"
"In the context of human biological populations, demographic analysis uses administrative records to develop an independent estimate of the population."
"For the 2010 U.S. Census, The U.S. Census Bureau has expanded its DA categories."
"Also, as part of the 2010 U.S. Census, DA now also includes comparative analysis between independent housing estimates and census address lists at different key time points."
"These methods have primarily been developed to study human populations but are extended to a variety of areas."
"In social human sciences, demographic analysis could involve the movement of firms and institutional forms."
"The broader field of social demography or population studies also analyses the relationships between economic, social, institutional, cultural, and biological processes influencing a population."
