Chapter 4: Population Aging Flashcards
What are the three major demographic components affecting population change?
Mortality, fertility, and migration.
What is the demographic transition, and what are its four stages?
developing countries went through 4 stages of demographic transition, affecting their population size and age structure:
o Population explosion (low mortality high birth rate)
o Population implosion (concentration of people in small areas, urbanization)
o Population “displosion” (more racial diversity bc of migration)
o “technoplosion” (rapid development and spread of technology)
Differentiate between a birth cohort and a generation.
A birth cohort is a group born in the same year, while a generation consists of cohorts who share defining life experiences.
What is the dependency ratio, and why is it rising?
The dependency ratio compares dependents (youth and elderly) to working-age adults (20-64). It’s rising due to population aging and less babies
demography
study why and how populations change over time and in size due to fertility, mortality and migration
what does demography develop?
Projections (NOT PREDICTIONS) about future size and location of populations
Easterlin
lifestyle differences between baby boomers and parents
health and epidemiological transition
health: population ages and leading causes of death change from illness to chronic diseases
epid: better food, water, hygiene and education
What are the generations?
o Baby boomers (1946-1964)
o Gen X (1965-80)
o Millennials/ gen Y (1981-1996)
o Gen Z (1997-2010)
what was the baby bust?
women could get jobs and the values in the home changed after WWII
UN reports that the rate of population aging is… (4 things)
unprecedented (older people with exceed younger people)
pervasive (impact all citizens)
profound (impact all aspects of life economic, social, political, health)
enduring (likely irreversible)
Lower fertility + lower immigration =
High fertility + high immigration =
+ proportion of older people
- proportion of older people
median age
chronological age at which population divides into equal numbers of old and young people
sex ratio
males per 100 females
females always outnumber males
are older people in more rural or urban areas?
older people tend to return home after they’ve lived in urban areas
allophones
immigrants who don’t speak english or french
