Global Demography Flashcards
defined as a group of individuals of the same species living and interbreeding within a given area
Population
rely on the same resources, are subject to similar environmental
constraints, and depend on the availability of other members to persist over time
Population
- This is the number of live births occurring per 1,000 individuals in a population within a given year.
- It provides a basic measure of the rate at which new individuals are added to the population.
Birthrate (Crude Birthrate)
- This rate reflects the average number of children a woman is expected to have during her lifetime, assuming she
experiences the age-specific fertility rates observed each year. - offers insights into generational replacement and population growth potential.
Total Fertility Rate (TFR)
- This is the median age a person is expected to live given the current mortality rates in a population. Life expectancy is
commonly used to assess the overall health, living conditions, and healthcare quality within a population.
Life Expectancy
- This is the number of deaths per 1,000 individuals in a population within a given year. It indicates the rate at which
individuals are lost from the population due to mortality.
Date Rate
– are people who move into a new country or region to live. From the perspective of the destination country
Immigrants
- This is the overall rate of population change, calculated by considering the difference between birth rates and death
rates and adding the net effect of migration (immigrants minus emigrants). Can indicate whether a population is expanding, stable, or declining and helps in forecasting future demographic and economic needs.
Growth Rate
– people who leave their home country or region to settle in another. From the perspective of the origin country,
Emigrants
was coined by Achille Guillard in 1855, in his work Éléments de Statistique Humaine ou Démographie Comparée
Demography
- refers to the distribution and characteristics of individuals within a population, often analyzed through factors such as age, sex, civil status, race or ethnicity, and education.
- These characteristics help reveal important demographic trends and social dynamics within society.
Composition of a population
This measures the percentage of individuals in various age groups within a population
Age composition
Guillard define _____ as “the mathematical knowledge of populations, their general movements, and their physical, civil, intellectual, and moral state.”
Demography
This refers to the proportion of males to females within a population.
Sex composition
- Often driven by factors like job opportunities, education, better living standards, or family reunification. This is common
in rural-to-urban migration within countries or in labor migration between nations.
Voluntary Migration
- This includes the movement of refugees, asylum seekers, and internally displaced people due to conflicts, natural disasters, persecution, or environmental changes.
Forced Migration
