1

Demographic equation

A formula that uses birth rates, death rates, immigration, and emigration statistics to show population growth.

New cards
2

Crude birth rate (CBR)

The annual number of live births per 1,000 people in a population.

New cards
3

Crude death rate (CDR)

The annual number of deaths per 1,000 people in a population.

New cards
4

Green Revolution

Increased food and nutrition, access to sanitation, education, and healthcare.

New cards
5

Rate of natural increase (RNI) formula

Birth Rate - Death Rate / 10%.

New cards
6

Net Migration Rate (NMR)

The number of immigrants minus the number of emigrants for every thousand members of the population.

New cards
7

Total fertility rate (TFR)

The estimated average number of children born to each female of birthing age.

New cards
8

Dependency ratio

The number of people too young or too old to work compared to the number of people in the workforce.

<p>Demographic transition model (DTM)</p>

Demographic transition model (DTM)

A theory of how population changes over time, providing insights into migration, fertility, economic development, industrialization, urbanization, labor, politics, and the role of women.

New cards
10
<p>Epidemiological transition model (ETM)</p>

Epidemiological transition model (ETM)

A model that accounts for development due to increasing population growth rates caused by medical advances.

New cards
11

Stage One - DTM

Historically characterized by pre-agricultural societies engaged in subsistence farming and transhumance, with high birth and death rates.

New cards
12

Stage Two - DTM

Typically agriculturally based economies with high birth rates, declining death rates, and rapid population growth.

New cards
13

Stage Three - DTM

Historically where most "industrialized" or manufacturing-based countries were found, with declining birth and death rates due to urbanization and fertility control.

New cards
14

Stages Four and Five - DTM

Converging birth and death rates resulting in limited population growth or decline, with service industries driving the economy.

New cards
15
<p>Malthusian Theory</p>

Malthusian Theory

The theory that global population would eventually outgrow the food supply, but food production has continued to stay ahead of population growth.

New cards
16

Sustainability

The ability to meet the needs of the present without compromising the ability of future generations to meet their own needs.

New cards
17

Population Pyramids

Graphical representations of the population structure, gender, and age distribution of a country or place.

New cards
18

Arithmetic density

The number of people per square unit of land.

New cards
19

Physiologic density

The number of people per square unit of farmland.

New cards
20

Overpopulation

A major concern in resource-poor regions and globally. It leads to the depletion of nonrenewable energy sources and decreased personal space.

New cards
21

Migration

The movement of people from one location to another, usually voluntarily

New cards
22

Push factors

Specific factors commonly about the rural agricultural landscape and livelihood that force people to leave, such as armed conflict or environmental pollution.

New cards
23

Pull factors

Specific factors commonly about cities that attract people somewhere, such as job opportunities or access to healthcare.

New cards
24

Interregional Migrants

People who move from one region to another within a country.

New cards
25

Transnational Migration

Movement of people across national borders, involving the relocation and settlement in a different country.

New cards
26

Forced Migration

Movement of individuals or groups who are compelled to leave their homes or countries due to factors such as conflict, persecution, or environmental disasters.

New cards
27

Amnesty Program

Government programs that allow undocumented immigrants the opportunity to apply for official legal status.

New cards
29

Step Migration

The gradual movement of people from rural areas to urban areas in a series of small steps driven by economic opportunities and better living conditions.

New cards
30

Chain Migration

The process where immigrants move to a new country because of existing connections with family or friends who have already settled there.

New cards
31

The various transitions and transformations that occur throughout an individual's life and can cause people to migrate.

New cards
32

Synonym for Birth Rate

Natality

New cards
33

Synonym for Death Rate

Mortality Rate

New cards
34

Rate of Natural Increase

Difference between the birth rate and the death rate in a population.

New cards
35

Reduced Fecundity

When the majority of women are heavily engaged in business, they are far less likely to have children.

New cards
36

Doubling Time

How long it would take for a country to double in size.

New cards
37

Replacement Rate

2.1 TFR

New cards
38
<p>Boserup theory </p>

Boserup theory

the more people there are, the more people can work instead of more mouths to feed

  • as pop increases = more pressure on agriculture system = inspires invention = more food

New cards
39

antinatalist policies

policies that attempted to reduce the number of children born in a country

  • used by developing countries

  • China One Child Policy - 1979-2016

  • 118 males:100 females

  • changes to 2 children in 2016

New cards
40

pronatalist policies

programs designed to increase fertility rates

  • paid time off, free childcare, government discounts

  • Denmark Singapore Italy Russia - promoted more children by national pride

New cards
41

What policies did Singapore have

both anti and pro

  • “Stop at Two” - 1966

  • “Have three or more if you can afford it “ - 1987

  • “Work Life Harmony” - 2000

  • paid leave, cash bonuses, tax rebates for working mothers

New cards
42

intervening obstacles

barriers that make migrants destination harder to reach

  • political - laws on immigration

  • environmental - deserts or oceans

  • walls and constructs

  • social - married to someone on route and settles in their community

  • economic - not enough money for destination

New cards
43

intervening opportunities

opportunities on route that disrupt their original migration plan

New cards
44

Ravensteins law of migration

<p></p>
New cards
45

Gravity model

as population of city increases = migration increases

distance to city grows = migration decreases

New cards
