Unit 2 Vocabulary Flashcards
Two-thirds of the world’s 8 billion people are found in the following four regions:
Europe
South Asia
Southeast Asia
East Asia
The habitable areas of the world:
Ecumene
Total population/land area (square miles):
Arithmetic
- Does not account for the uneven distribution of population within each country
- No clustering/dispersal info
Arithmetic Advantages/Disadvantages
Total population/arable land:
Physiological
The max. population size that can be supported with the available resources without damaging the environment:
Physiological Advantages/Disadvantages
The max. population size that can be supported with the available resources without damaging the environment (Definition):
Carrying Capacity
Farmers/Arable Land:
Agricultural
- Compares the number of farmers to the area of arable land
- Better indicators of a country’s level of economic development rather than population distribution
Agricultural Advantages/Disadvantages
High population density impacts access to housing, jobs, water, and services like sanitation, medical care, fire, police, public transportation and waste collection:
Social Services and Infrastructure
What percent of the population are children? The elderly? Male? Female?
Population Structure
Show the population Structure/composition of a location:
Population Pyramid
Population pyramids are used to assess population ______ and ______ and to predict ______ for goods and services:
Growth, decline, markets
The number of people in a dependent age group divided by the number of people in the working age group multiplied by 100:
Dependency Ratio
Number of people not working:
A High Dependency Ratio
- The elderly pay less income taxes
- Supported by a gov. sponsored retirement funds
- As life expectancy increases, so do healthcare costs
- Provide opportunities for employment in the eldercare industry
- Volunteer Work
Economic Impacts of an Elderly Dependency Ratio
- Traditional families
- Living facilities for the elderly
- Provide social support to families
Social Impacts of an Elderly Dependency Ratio
- Typically the most politically active group in many places
- Different perspectives on political issues
Political Impacts of an Elderly Dependency Ratio
The proportion of males to females in a population:
Sex Ratio
Factors that Determine a Population’s Growth and Decline:
- Fertility (Crude Birth Rate and Total Fertility Rate)
- Mortality (Life Expectancy, Crude Death Rate, Infant Mortality Rate)
- Migration
The number of births occurring in one year er 1,000 people:
Crude Birth Rate
Average # of children who would be born per woman during her childbearing years:
Total Fertility Rate
The number of deaths occurring in one year per 1,000 people:
Crude Death Rate
The # of children who die before on year of age:
Infant Mortality Rate
Natural Increase Rate:
1. Does not account for _______
2. Can be a _____ number, indicating population _____
3. Usually expressed in a ______
Migration, negative, percentage
Crude Birth Rate - Crude Death Rate/0 =
Equation for NIR
Population Growth Rate:
1. More _____ measure because it accounts for ______
2. Immigrants
3. Emigrants
Accurate, migration
(Births-Deaths) + (Immigrants - Emigrants) =
Equation for Population Growth Rate
The number of years in which a population will double assuming the growth rate remains stable:
Doubling Time
70/NIR =
Equation for Doubling Time
The study of population statistics:
Demography
Used by geographers to analyze and predict trends in population growth and decline, including patterns of birth deaths and natural Increase rates:
The Demographic Transition Model
Predictable stages in disease and life expectancy that countries experience as they develop which corresponds with the stages of the DTM:
The Epidemiological Transition Model
CBR: High
Reasons for CBR: Kids are not likely to survive long-term (need for child labor in agricultural societies)
CDR: High
Reasons for CDR: Short life expectancy, famine, poor diet, bad housing, disease, war
NIR: Low Growth
Pop Composition: Youth Dependency
Stage One of DTM
CBR: High
Reasons for CBR: Kids are not likely to survive long-term
CDR: Falls Rapidly
Reasons for CDR: Better nutrition, medicine, and sanitation
NIR: Rapid Growth
Pop Composition: Youth Dependency
Stage Two of DTM
CBR: Falling
Reasons for CBR: Urbanization reduces the need for child labor and increase in healthcare
CDR: Falls More Slowly
Reasons for CDR: Life expectancy increases due to progression from previous stages
NIR: Growth Slows
Pop Composition: People are surviving longer
Stage Three of DTM
