1. Factors that limit population size - ANSWER disease, war, famine,
migration, high infant mortality, cultural factors (late marriage) etc.
2. Carrying Capacity - ANSWER number of organisms in a given species that
can be supported indefinitely
3. Malthus - ANSWER Wrote "An Essay on the Principle of Population" 1798
-predicts population (exponential growth) will outgrow food supply (steady
growth)--environmental degradation
4. Demography - ANSWER -The scientific study of population ecology to the
study of humans
-Vital statistics: population size, structure, sex, age, BR, DR, migration
5. Most developed countries (MDC) - ANSWER -populations expected to
stabilize or decline
-wealthy, old, mostly shrinking
-average age: 40
-North America, Western Europe, Japan
6. Population Dynamics - ANSWER -study of how characteristics of a
population (i.e. BR/DR) can change in response to environmental conditions
,-indicate fluctuation of population size
7. Factors of global population increase - ANSWER -high birth rate/low death
rate
-increased food supply & nutritional value
-medical access/medicine
-improved technology
(increased life expectancy)
8. reasons for projected increased growth rate in US - ANSWER -more
unmarried mothers
-higher fertility rate (racial groups apart from caucasian)
-more immigration (legal & illegal)
-religious belief
9. Population growth viewpoints
(Economist, Ecologist, Social Justice Advocates) - ANSWER Economist:
technology/economic growth can increase carrying capacity
Ecologist: human population growth is overloading the system
Social Justice Advocates: problem is uneven distribution of resources across
populations.

children a woman produces in her child bearing years
18.Replacement Fertility Rate - ANSWER number of offspring a couple
produces to replace themselves

and crude death rate (BR - DR)
20.Factors that affect life expectancy. - ANSWER -age
-healthcare/technology
-nutritious food
-better sanitation
-awareness/availability of resources (health care)
21.Dependency Ratio - ANSWER -number of non-working compared to
working individuals in a population
-US concern: not enough incoming working class to replace retired
22.Poverty & Population Growth factors - ANSWER -higher poverty levels
equate to higher population growth
-economic development allows for population control (education in family
planning & access to resources)
23.Empowering women - ANSWER -education plays vital role in giving
women the power to make decisions regarding their lives and reproductive
behavior.
