Quiz #1 Flashcards
lifetime
fixed, finite maximum limit of survival for a species
- apx. 120 years for humans
main causes of population aging
Mortality rate decrease (life expectancy increase)
Fertility rate decrease
mortality rate decrease (life expectancy increase)
- Life expectancy: average number of years a person is projected to live at birth
- Increased through improvements in sanitation, public health, health care
- In canada: 83 years for women, 79 years for men
- Varies by gender, culture, geographic region, ethnicity, race, education, personal habits, birth cohort
fertility rate decrease
- Canada’s birth rate is apx. 11 infants per 1000 population, down from about 27 per 1000 in 1946 at start of the “baby boom” (1946-1965)
- With fewer births and aging baby boomers, older people comprise a larger percentage of the population
- Fertility rate is currently below”replacement rate” needed to replenish the population
- Population decrease is offset by immigrants arriving in Canada
does population aging occur in a vacuum? (does it not affect other things?)
- Population aging does not occur in a vacuum
- Effects of population aging permeate the social world including work and family, and public policy, the economy, health care, housing, and transportation
- However, with health promotion, health care improvements, higher levels of education, and with proper policy planning, an older population will not necessarily drain pension and health care systems
life course perspective
- examines the interplay among individuals life stories, our social system and institutions, and environments
- Framework for understanding age related transitions that begin with birth and entry into the school system and conclude with retirement, widowhood, and death
- We can observe and analyze how different individual or societal events create variations in the aging process within and between cohorts and individuals
- Eg. a war may affect some age cohorts but not others
- How problems, advantages, disadvantages, needs, and lifestyles of later life are shaped by earlier life transitions, decisions, opportunities, and experiences
agency
- a process in which individuals construct their life course by making choices and taking actions
- Through agency we create unique identities, develop personal meanings and expectations, and decide which social groups are significant in our lives
- These intentional choices are strongly influenced by constraints and opportunities of social structures by personal history and past experiences, and by significant others in our daily lives
four aspects of individual aging
Chronological
Biological
Psychological
Social
chronological age
Passage of calendar time from one birthday to the next
Defines “legal” age
Provides order and control in society
biological age
- Changes in cellular, muscular/skeletal, neural, cardiovascular, sensory systems
- These changes influence:
- The number of years a person is likely to survive
- The extent to which he or she is likely to experience illness or disability
- Visible changes such as graying hair or wrinkling skin influence how one is viewed
psychological aging
- Changes in learning ability, memory, creativity
- Interaction of cognitive and behavioral changes with social and environmental factors
- Eg. loss of spouse, change in housing
- Influenced by cultural differences
social aging
- Changes in social roles and relationships
- The behavior and status are influenced by rights and responsibilities assigned on the basis of age or age group and by attitudes toward specific age groups as defined by society
demography
- the study why and how populations change over time and become smaller, larger, or older due to the interrelationships among fertility, mortality, and migration patterns
- Demographers use a variety of tools, including tables, graphs, and figures to illustrate demographic trends and patterns about the past and future
demographic transition
- a shift from high fertility and high mortality to low fertility and low mortality
- From 1800’s and beyond, developed countries went through four stages of a demographic transition, affecting their population size and age structure
1) Population explosion
2) Population implosion - population became concentrated in small urban areas
3) Population “displosion” - population became more heterogeneous due to immigration
4) “Technoplosion” - spread of new technology, creating improvements in public health (such as disease control, public sanitation, and health promotion) and longevity
epidemiological transition
- As a population ages, leading causes of death change from acute/infectious to chronic/degenerative diseases
- this trend began once there were improvements in food distribution, nutrition, water quality, personal hygiene, public sanitation, education, and economic development
- As a result, life expectancy rises, and leading causes of death become the chronic and degenerative diseases later in life
demographic analyses
enable us to understand variations in the size, composition, lifestyle, life changes of different generations
generation
- a set of birth cohorts who share particular life experiences and exhibit characteristics that distinguish it from other generations
- Eg. baby boomers - born between 1946-1965
