Ch. 2/3: Population and Health/ Migration Flashcards
Highly clustered/ concentrated regions in the world
East Asia, South Asia, Europe, and Southeast Asia
Smaller concentrated/ emerging regions
Eastern North America and West Africa
Permanent human settlement
Ecumene
Sparsely populated by humans
Non-ecumene
Total # of objects in an area
Arithmetic density
of people supported by a unit area of arable land
Physiological Density
The ratio of # of farmers to arable land
Agricultural density
Total # of live births in a year for every 1,000 people alive
Crude Birth Rate (CBR)
Total # of deaths in a year for every 1,000 people
Crude Death Rate (CDR)
% by which the population increases in a year
Natural Increase Rate (NIR)
The amount of time needed for doubling the population
Doubling Time
The average amount of children a woman has in her child-giving years (ages 15-49)
Total Fertility Rate (TFR)
The # of people who are too young or too old to work
Dependency Ratio
A process with several stages and every country is in one of the stages
Demographic Transition
- High CBR
- High CDR
- No NIR
Stage 1 (Low Growth)
- Declining CDR
- High CBR
- High NIR
- e.g. Cape Verde
Stage 2 (High Growth)
- Declining CDR
- Declining CBR
- Rising NIR
- e.g. Chile
Stage 3 (Declining Growth)
- Low CBR
- Low CDR
- No long-term NIR
- e.g. Denmark
Stage 4 (Low Growth)
Argued that the population of the world will grow more rapidly than the food supply
Thomas Malthus
Argued that recent population growth makes Malthus’ theory more frightening
Neo-Malthusians
Focuses on distinctive health problems in each demographic transition/stage
Epidemiologic Transition
- Pestilence & Famine (e.g. Black Plague)
Stage 1 (High CDR)
- Receding Pandemics (diseases that affect a high proportion of people e.g. cholera)
Stage 2 (Rapidly declining CDR)
- Degenerative Disease (e.g. heart disease and cancer)
Stage 3 (Moderately declining CDR)
- Delayed Degenerative Disease
Stage 4 (Low but Increasing CDR)
- Infectious and Parasite disease
- Poverty
- Increased connections
Possible Stage 5 (Rising CDR)
Annual # of Deaths among infants under the age of 1 (per 1,000 infants)
Infant Mortality Rate
The average # of years people are expected to live
Life expectancy
Designed to increase birth rates (e.g. Russia and China)
Pro-Natalist
