New cards

Five major population agglomerations

  • East Asia
  • South Asia
  • Europe
  • Southeast Asia
  • Eastern part of North America
2
New cards

Ecumene

The portions of Earth’s surface occupied by permanent human settlement

3
New cards

Arithmetic density

People/total land area

  • aka population density
  • EX: 84.5/ sq miles OR 85.4 mi^2
  • Shares a little about population distribution, but doesn’t indicate where in the total area they live
4
New cards

Physiological density

People/arable land

  • measures the pressure on agriculture land in a country
  • A small percentage of a region’s land is capable of growing crops
  • More useful to determine a regions carrying capacity
5
New cards

Agricultural density

Farmer/arable land

  • measures of relationship between population and resources and the level of a country’s development
  • Gives indication of the efficency of the regions farmers
  • Developed countries have a low agricultural population density because the farmers have more tech to produce large amounts of food with low workers
6
New cards

Carrying capacity

the population a region can support without signification environmental deterioration

  • can change overtime
  • EX: technological changes in agriculture can increase this
7
New cards

Age structure

Percentage of the population (or number of people of each sex) at each age level in a population

  • youthful, aging, maturing, and declining
8
New cards

Sex ratio

The number of males per 100 females in the population

  • in more developed countries there’s more women because they’re expected to live longer
9
New cards

Population pyramid

Age-sex composition graph based on only gender and age data that shows information on birthrates, death relates, how long people live on average, and economic development

  • can show past events (war, baby booms, baby busts, etc)
10
New cards

Demographic momentum

the tendency for growing population to continue growing after a fertility decline because of their young age distribution

  • important because this happens once a country moves to a different stage in the dtm
11
New cards

Crude birth rate

The number of live births per year for each 1000 people

  • education and healthcare, and contraceptives can cause this to decline
12
New cards

Total fertility rate

the average number of children who would be born per woman of that group in a country, assuming every woman lived through her childbearing years

  • reflects cultural norms
  • Changes with social, economic, and political roles
13
New cards

Infant mortality rate

The number of children who die before their 1st birthday

  • one of the most important factors that affects increasing life to drop
14
New cards

Crude death rate

Number of deaths of an area per 1000 population

15
New cards

life expectancy

The average number of years people live

  • commonly expressed from the time of a person’s birth
  • Can change with current social, economic and medical conditions
16
New cards

Replacement fertility

the total fertility rate at which women would have only enough children to replace themselves and their partner

  • rate is mostly 2.1 children
17
New cards

Zero population growth

A decline of the total fertility rate to the point where the natural increase rate equals zero

  • more developed countries are either at or near zero population growth
18
New cards

Doubling time

The time it takes a population to double in size can be estimated using the rule of 70/72

19
New cards

Demographic equation

  • Future population = Current population + (number of births – number of deaths) + (number of immigrants – number of emigrants)
  • Used to describe the future population of a region of any scale
20
New cards

Net migration

The difference between the level of immigration and the level of emigration

  • includes citizens and non citizens
21
New cards

DTM stage 1

High birth rate and death rate, low population growth

  • EX: no countries today
<p>High birth rate and death rate, low population growth</p>
<ul>
<li>EX: no countries today </li>
</ul>
22
New cards

DTM stage 2

  • high birth rate, falling death rates (medical revolution)
  • high population growth
<ul>
<li>high birth rate, falling death rates (medical revolution)</li>
<li>high population growth</li>
</ul>
23
New cards

DTM stage 3

  • moderate growth

  • declining birth rate (education and healthcare) and a more slowly declining death rate

    • urbanized and more industrialized families have less children
  • EX: Mexico, Turkey, Indonesia

<ul>
<li><p>moderate growth</p></li>
<li><p>declining birth rate (education and healthcare) and a more slowly declining death rate</p>
<ul>
<li>urbanized and more industrialized families have less children</li></ul></li>
<li><p>EX: Mexico, Turkey, Indonesia</p></li>
</ul>
24
New cards

DTM STage 4

  • typically the stationary population pyramid and indicates a population that is not significantly growing or shrinking
  • steady/low birth rate
  • low death rate -> high life expectancy
  • EX: United States, China
<ul>
<li>typically the stationary population pyramid and indicates a population that is not significantly growing or shrinking</li>
<li>steady/low birth rate</li>
<li>low death rate -&gt; high life expectancy</li>
<li>EX: United States, China</li>
</ul>
25
New cards

DTM Stage 5

  • negative growth
  • decreasing birth rate
  • death rate exceeds birth rates 
  • EX: Japan, Germany
<ul>
<li>negative growth</li>
<li>decreasing birth rate</li>
<li>death rate exceeds birth rates&nbsp;</li>
<li>EX: Japan, Germany</li>
</ul>
26
New cards

Epidemiological transition model

  • created by Abdel Omran to explain the changing death rates and more common causes of death within societies
  • Stage 1 - FAmine and Disease
  • Stage 2 - Receding Pandemics
  • Stage 3 - Degenerative and Human-Created Diseases 
  • Stage 4 - Delayed Degenerative Diseases
  • Stage 5 - Reemergence of Infectious and Parasitic Diseases
27
New cards

Thomas Malthus’ theory

\n the world's population was growing faster than the rate of food production, and as a result, mass starvation would occur

  • people need to exercise “moral restraint”
  • The poor shouldn’t receive social services
  • No more public school
28
New cards

Thomas Malthus theory carrying capacity

  • more humans than available resources

  • the human population will outgrow the carrying capacity therefore we need to stop population growth

29
New cards

Sustainability

The idea that socially responsible companies will outperform their peers by focusing on the world’s social problems 

  • the saving of resources for future generation to allow them to live at the same or higher standard of living than the population today
30
New cards

Overpopulation

\n the number of people in an area that exceeds the capacity of the environment to support life at a decent standard of living

31
New cards

Preventive checks

measures taken by humans to reduce shortages

  • could be reducing the population through better financial planning and possibly anti-natalist policies
  • could be reducing waste through better recycling
32
New cards

Positive checks

Events that increase deaths

  • the effects of war, disease and famine in controlling excess population growth
33
New cards

\n Esther Boserup’s theory of agricultural intensification (a.k.a. “Cornucopian Theory”)

  • as population would increase, there would be more food production because there would be more pressure on the agricultural system
  • rejects the idea that population growth is problematic because Earth has finite resources and carrying capacity
34
New cards

Neo- Malthusian theories

  • argue that population growth is a serious problem and is a greater threat for the future
  • believe that continued population growth will lead to the depletion of nonrenewable resources such as petroleum and metals, pollution
35
New cards

Anti-natalist policy

\n policies that attempt to decrease the number of births in a country and are often used by developing countries

  • Ex: China’s one child policy
36
New cards

Pro-natalist policy

Programs designed to increase the fertility rate

  • used to keep the economy vibrant
  • EX: provided pto for mothers, free childcare, and family discounts on governmental services
37
New cards

\n International Conference on Population and Development (ICPD) (example to know and cite)

a conference aimed at looking for a beyond solution for slowing population growth that was not family planning

  • The goals of the ICPD were to advance human rights and individual dignity by improving the quality of life for everyone. They wanted to improve sexual and reproductive health, women’s empowerment, and an end to gender violence and traditional practices. They said that if we invest in women and you, the sustainability and population dynamics will be impacted
38

  • immigration - emigration 
44
New cards

Push factor

\n negative circumstances, events, or conditions present where they live that compels a person to leave

EX: political instability, wars, poverty, natural diasaters

45
New cards
46
New cards

Pull factor

\n a destination based on its positive conditions and circumstances that migrants are drawn to after they leave their old location

  • EX: a migrant might find a job along the way
50
New cards

Intervening obstacle

\n barriers that make reaching their desired destination more difficult

51
New cards

\n Ravenstein’s “Laws of Migration”

  • short Distances: most migrants only travel a short distance (distance decay)

  • Urban Areas: migrants traveling long distances usually settle in large urban areas

  • Multiple Steps: most migration occurs through step migration (a process in which migrants reach their eventual destination through a series of smaller moves

  • Rural to Urban: Most migration in history has been from rural agricultural areas to urban city areas

  • Counter Migration: each migration flow produces a movement in the opposite direction

    • EX: while migrants from Mexico came to USA, some retired US citizens migrated to Mexico for weather
  • Youth: most migrants are younger adults between 20-45

    • they’re more likely to leave because they don’t have as much to hold onto
  • Gender Patterns: most international migrants are young males, while more internal migrants are female

    • women who live in traditional societies move in with their husbands
52
New cards

Migration selectivity

  • Age - younger people 18-30 are most likely to move

  • education - people with a higher education are most likely to make long distance moves

  • kinship & friends- people will follow family members that have moved to another area for a better life - chain migration helped create cultural neighborhoods

53
New cards

58
New cards

Internally displaced person

\n when migrants flee quickly to stay alive and can’t bring many items with them but they only move to another part of the same country

59
New cards

Chain migration

\n When people migrate to and settle in a new country, they often decide to locate in a city or community where others from their home country, family members, friends, or those from their culture group have previously settled 

60
New cards

Step migration

61
New cards

Transhumance
