soci Flashcards
environmental sustainability
the degree to which a human activity can be sustained without damaging or undermining basic ecological support systems
capital accumulation
refers to the reinvestment of profit in order to increase capital assets
demography
the study of populations
growth rate
the current population - initial population/initial x 100
population composition
changing fertility, mortality and migration rates
sex ratio
number of men for every 100 women
population pyramid
population distribution by sex and age
malthusian theory
three factors would control human population that exceeded the earth’s carrying capacity
three factors of Malthusian theory
war, famine and disease
positive checks
increase mortality rates - keeping the population in check (war, famine and disease)
preventative checks
i.e. birth control and celibacy
reasons people have not died off
technological increases in food production, new medicine, contraception
zero population growth (ZPG)
the number of people entering a population through birth or immigration is = to number of people leaving it via death/emigration
cornucopian theory
human ingenuity can resolve any environmental or social issues that develop
demographic transition theory
future population growth will develop along a predictable four-stage model
stage 1 of demographic transition theory
birth, death, and infant mortality rates are all high, life expectancy is short, i.e. 19th cen North America
stage 2 of demographic transition theory
birth rates are higher while infant mortality and the death rates drop, life expectancy also increases, i.e. Afghanistan
stage 3 of demographic transition theory
once a society is thoroughly industrialized, birth rates decline while life expectancy continues to increase, death rates continue to decrease, i.e. Mexico currently
stage 4 of demographic transition theory
postindustrial era of society, birth and death rates are low, people are healthier and live longer, population stability, population may even decline, i.e. Sweden and Canada
urbanization
study of social, political and economic relationships in cities
3 prereqs for development of a city
- good environment with freshwater/favorable climate
- advanced technology
- strong social organization
gentrification
members of the middle and upper classes entering city areas that have been historically less affluent; renovating while the poor urban underclass are forced
megalopolis
toronto-hamilton-oshawa, vancouver-abbotsford-chilliwack, calgary-edmonton; NEW YORK
human ecology
focuses on the relationship between people and their built/natural physical environments
