Unit 2 APHG Key Terms
2.1
Physical factors: climate, weather patterns, landforms, bodies of water and natural resources
Human factors: economic, cultural, historical and political aspects
Arithmetic density: show how densely populated a place is: total pop/total amount of land - assumes everyone is spread out evenly across area
Physiological density: pressure that a population exerts on the environment to feed the population - total pop/total amount of arable land
Agricultural density: level of efficiency of ag. Production in an area and the degree of reliance on human labor vs technology - amount of farmers/total amount of arable land (high number = more labor)
2.2
Urban sprawl: unrestricted growth and expansion of an urban or suburban area into the surrounding countryside
Carrying capacity: amount of people that can be supported by the environment without damaging it
2.3
Demographic characteristics: age, gender, ethnicity, educational attainment, income
Age categories of population pyramid: pre-reproductive years (0-14), reproductive years (15-44), post-reproductive years (45+)
Sex ratio: (male births in society/female births in society) x 100
If above 100 then more males in society but if less then more females
Dependency ratio: how many ppl society needs to support
2.4
Crude birth rate (CBR): total # of live births in a year for every 1000 ppl alive in society
Crude death rate (CDR): total # of deaths in a year for every 1000 ppl alive in society
Natural Increase Rate (NIR): % by which pop. grows in a year
(NIR = CBR - CDR)
Total fertility rate (TFR): average # of children a woman will have (if below 2.1 then pop. will decrease and if above then pop will increase)
Infant mortality rate (IMR): total # of deaths under 1 yr of age in a year for every 1000 live births
2.5
Emigration: when individual leaves country or political territory
Demographic transition model doesn’t factor immigration and migration
Stage 1: high CBR, high CDR, low NIR - women have limited opportunities (no countries in this stage)
Stage 2: high CBR, decreasing CDR, significant NIR (ex. Afghanistan)
Stage 3: decline CBR, decrease CDR, NIR more moderate (ex. Mexico)
Stage 4: low CBR, low CDR, low to flat NIR - sometimes ZPG (ex. USA, China)
Stage 5: low CBR, low CDR and negative NIR, decline in pop (ex. Possibly Japan or Germany)
Zero population growth (ZPG): when country’s CBR and CDR = same causing NIR to be 0
Epidemiologic transition model (stage 1-4 pair w/ DTM but stage 5 doesn’t connect):
Stage 1: vulnerable to many diseases, famine, pandemics, epidemics, food shortages, etc. (ex. Plague)
Stage 2: improved standard of living, increase food prod., more nutritious food, better sanitation
Stage 3: degenerative diseases (ex. Heart disease, Cancer), live longer
Stage 4: fighting degenerative diseases, overall longer life expectancy, good healthcare, improved diets and lifestyle
Stage 5: resurgence of infectious diseases, evolution of disease, increased poverty, increased urbanization, globalization (ex. COVID)
2.6
Malthusian theory: theory where population would surpass carrying capacity = famine, war, disease outbreaks and collapse of society
Believed intervention was necessary to prevent uncontrolled pop. growth (ex. gov. could implement anti-natalist policies)
Ended up being wrong
2.7
Pro-natalist policies: policies created to help increase a society’s birth rate - typically implemented in countries w/ low or negative NIR
Anti-Natalist Policies: policies created to help decrease society’s birth rate - countries with high NIR (ex. China w/ one child policy)
Immigration policies often based $ needs, national security priorities and cultural values
2.8
Increased education for women = lower fertility rate, infant mortality rate and maternal mortality rate
Maternal mortality rate: measure # of maternal deaths per 100,000 live births that occur due to pregnancy or childbirth-related complications
Ravenstein’s law of migration: most migration happens for $ reasons and mostly undertaken by young adults - rural to urban
Large urban areas often experience pop. growth through migration rather than natural births
Women more likely to migrate internally w/in country while young males most likely to migrate internationally
Gravity model: based on assumption that migration flows influenced by migration size and distance between origin and destination
2.9
High dependency ratio can lead to reduction in $ growth as countries raise taxes to support aging pop.
2.10
Pull factors: positive, situations, conditions, events and factors that make people want to move to geographic location (ex. More business opportunities, less taxes, political stability, acceptance of different cultures, less pollution)
Push factors: negative conditions that make people want to leave their current geographic location (ex. Lack of job opportunities, discrimination, religious persecution, natural disasters)
Emigration: when individual leaves country or territory
Immigration: when individual enters country or territory
Intervening obstacles: negative situations that hinder migration and prevent migrants from reaching final destination (ex. Denied entry)
Intervening opportunities: positive situations that hinder migration (ex. Find job offer on the way)
2.11
Forced migration: when migrant has no choice but to migrate (ex. Slavery, human trafficking, war)
Refugee: individual who has been forced to leave home country and crossed international border to escape
Internally displaced person (IDP): individual who has been forced to flee home but has not crossed internationally recognized state borders
Voluntary migration: when ppl. choose to leave country for more opportunities
Transnational migration: when migrant emigrates from home country but remains connected to original country
Chain migration: process where legal immigrants sponsor family member to immigrate to country
Step migration: migration that happens in stages/steps
Guest workers: migrant temporarily migrates to new country for work or educational reasons
Remittance: money an immigrant sends back to family residing in home country
Transhumance migration: migration that revolves around seasonal movement of livestock between 2 diff. locations
Intraregional migration: migration that involves permanent move w/in same region
Interregional migration: migration that involves permanent move from one region to another region of same country
2.12
Increased immigration often = increased talent as gain more skills and knowledge
Brain drain: when skilled labor leaves geographic area in favor of another area that offers more opportunities
Acculturation: when culture adopts different cultural traits of another culture
Assimilation: when culture adopts new cultural resulting loss or original culture
Syncretism: when 2+ cultures evolve or change over time in similar manner but remain culturally distinct
