Soc (chapter 15)
Demographic Transition Theory stages
1- high birthrates and death rates which balance each other out (most of human history) 2-still high birthrates but death rates decline (improvements in healthcare, increased availability of food) leads to HIGH population growth 3-population levels off because of increased contraception, wage increases, urbanization, increased eduction (characteristic of most industrial societies) 4-birthrates and death rates both low (birth rates is some Global North countries drop below replacement level, leading to declining population)
Population Replacement
?birthrate which just replaces the population (@ 2 children per woman)
Sex Ratio
ratio of males to females in the population
Dependency Ratio
the ratio of those in both the young and aged groups compared with the number of people in the productive age-group from age 15 through age 64
Demography
the study of human populations
How are baby boomers affecting the population pyramid in the US
they are increasing the number of over 64 age-dependent population presently has increased to 14% and is predicted to increase to 20% by 2035
Positive Checks (Malthus' theory)
things that lead to higher death rate such as war, disease, epidemics (Malthus)
Preventative Checks (Malthus' theory)
things that result in lower birthrates such as delaying marriage and abstinence (Malthus)
what do demographers focus on?
various aspects of a population - size, location, movement, concentration in certain geographical areas, changes in characteristics
megacity
city and surrounding metropolitan area with more than 10 million people
Immigrants
people who migrate
Gesellschaft
German term meaning "a modern society with impersonal relationships" -key elements are more formal relations, contracts, laws, and economies built on money -characteristic of urban societies Used in Tonnies theory
Gemeinschaft
German term meaning "small traditional community" -key elements are family, friendship, relations to the land, common values, and traditions -Used in Tonnies theory
Migration
in terms of demographic processes, refers to the movement of people from one place to another
Refugees
those who flee in search of refuge in times of war, political oppression, natural disaster, or religious persecution
organic solidarity
Durkheim's term for the glue that hold modern industrial and postindustrial societies and people together -based on a division of labor with each member playing a highly specialized role in the society and each person being dependent on others due to interrelated, interdependent tasks -this interdependence of specialized tasks is the key to unity in more complex societies
mechanical solidarity
Durkheim's term for the glue that holds a society together through shared beliefs, values, and tradition typical of rural areas and simple societies
Infant mortality rates
Global North - 5 Global South (less affluent) 40 Global South (least affluent) 62
which countries have the highest age dependency ratios?
Japan (@25% over 65yo), Norway, Sweden, Denmark, Germany, Great Britain (15-20%) -hard for the countries to support that large of an aging population
which countries have the highest youth dependency ratios?
Niger, Kenya, Congo, Afganistan -in these countries almost 50% of the people are under 15 -this makes it very difficult for the working age people to support them (especially if they are urban)
does the united states have a megacity?
Yes, New York (most are in Global South)
Infant Mortality
deaths of children under one year of age (number of death before age 1 per thousand live births)
4 major institutions which affect fertility rates
economy, politics, religion, education
three major processes which can change a population
fertility, mortality, migration
Antinatalist
government policies which discourage fertility (example: Singapore, China one-child policy)
Pronatalist
government policies which encourage fertility (such as incentives) example: Eastern Europe - gave time, cash incentives etc for children to increase childbearing
fertility rates in Global South countries
high
Malthus' Theory of Population
humans are driven to reproduce and will multiply excessively without checks imposed to slow population growth. -population growth must be controlled by "positive checks" and "negative checks"
Populations
identifiable categories of people such as people in particular societies, states, communities, adherents of a common religious faith, racial or ethnic groups, kinship or clan groups, professions, etc
Global South
less affluent nations (developing, poor countries mainly in the Southern Hemisphere)
Demographic Transition Theory
links trends in birthrates and death rates with patterns of economic and technological development
fertility rates in Global North countries
low
Global North
more developed or affluent countries (mainly in the Northern hemisphere)
Urbanization
movement from rural to urban areas
International Migration
movement of people across national boundaries
Internal Migration
movement of people within a country
Youth Dependency Ratio
number of children under 15 divided by the number from 15 to 64
Age Dependency Ratio
number of people older than 64 divided by those age 15-64
what is push-pull theory of migration
people are PUSHED to leave by war, famine, economic crises, etc people are PULLED by economic opportunities or political or religious tolerance
Babyboomers
people born in the post World War II baby boom (between 1946 - 1963)
asylum
protection granted by a nation to someone who has left their native country as a political refugee.
Population Pyramids
pyramid-shaped diagrams that illustrate sex ratios and dependency ratios over time
Gentrification
refers to members of the middle and upper class, mostly young White professionals, buying and renovating rundown properties in central-city locations and displacing poor residents
how many refugees, asylum seekers and internally displaced persons in world today
refugees - asylum seekers internally displaced people
Population Momentum
skyrocketing growth rate caused by the large number of individuals of childbearing age having children (even if the # of births/person is going down, there is still a boom because there are so many people of childbearing age)
Asylees
someone who has been seeking or has been granted asylum
Internally Displaced Persons
someone who is forced to flee their home but remains within their country's borders
Life Expectancy
the average number of years a person in a particular society can expect to live
Fertility
the birth rate
Mortality
the death rate
