Number of Farmers divided by the arable land

Arable Land

Land suitable for farming/agriculture

Physiological Density

Epidimiology

Branch of medical science concerning diseases

Industrial Revolution

Time during the 19th century, major improvements in manufacturing goals and delivering them to market

Infant Mortality Rates

Annual number of deaths of infants(one and under) compared to the number of live births

Less Developed Countries (LDC)

Non-industrialized/poor countries.

Stage two, early three

Life Expectancy

Average number of years an infant can expect to live

Thomas Malthus

An English economist who was one of the first to argue that the world's population increase was far outrunning the development of food production

Malthusian Theory

The theory that population grows faster than food supply

Medical Revolution

Time during the late 20th countries, when medical technology from Europe and North America diffused to developing countries

More Developed Countries

industrialized country.

Stage 4/5

Natural Increase Rate

Percent a population grows in a year

Neo-Malthusians

People who believed in Malthusian Theory and in the idea that population was not only outstripping food but other resources

Population Density

Measurement of population per area or unit

Population Distribution

Pattern of where people live- how people are spread out

Population Pyramids

Country's distinctive population showed on a bar graph- males on left

Anti-Natalist Policies

Government policies to reduce the rate of natural increase

Pro-Natalist Policies

Government policies to increase the rate of natural increase

Sex Ratio

Number of males per 100 females

Total Fertility Rate

Average number of children a woman will have during her 'birthing' years

Zero Population Growth

When the CBR and the CDR are equal and the NIR approaches zero

Demography

The scientific study of population characteristics

Over-Population

When the number of people in an area exceeds the capacity of the environment to support life at a decent standard of living.

Population Concentration

An area of land where people are most dense, including East Asia, South Asia, Southeast Asia, and Europe.

Demographic Transition Model

A model that demonstrates the shift in population growth throughout time

Stage 1 DTM

Low Growth: A pre-industrial agrarian society with a High CBR, High CDR, and a Zero NIR

Stage 2 DTM

High Growth: Industrializing society with a CBR that remains high but stable, a CDR that declines dramatically, and a NIR in rapid increase.

Stage 3 DTM

Decreasing growth: Industrializing society with a CBR that declined significantly, a CDR that continues to decline, and a NIR that begins to moderate.

Stage 4 DTM

Low Growth: A Modern Industrialized Country with a low CBR, low CDR, and virtually no NIR

Stage 5 DTM

A Modern Industrialized Country with a very low CBR, an increasing CDR, and a negative NIR

Declining Birth Rates

Education and Health care and Contraceptives have been useful methods

Epidemiologic transition model

A model highlighting the distinctive causes of death in each stage of the demographic transition

Stage 1 ETM

Pestilence and Famine (high CDR)

-infectious and parasitic diseases, accidents and attacks by animals and humans, and other natural causes are principal reasons for human death

-ex. the Black Plague

Stage 2 ETM

Receding Pandemics (rapidly declining CDR)

-results from overcrowding

-ex. cholera outbreak

Stage 3 ETM

Degenerative/Chronic Diseases (moderately declining CDR)

-a decrease in deaths from infectious diseases and an increase in chronic disorders (e.g. cardiovascular diseases) associated with aging

Stage 4 ETM

Delayed Degenerative Diseases (low but increasing CDR)

-The major degenerative causes of death - Cardiovascular diseases and Cancers- linger, but the life expectancy of older people is extended through medical advances

Stage 5 ETM

Reemergence of infectious diseases

-Infectious diseases thought to have been eradicated or controlled return and new ones emerge

-Evolution, Poverty, and increased connections

3 reasons for stage 5 of the ETM

1. Evolution-infectious diseases have evolved and developed resistance to drugs

2. Poverty-infectious diseases are more prevalent in poor areas because of unsanitary conditions

3. Increased Connections-more contact with people through relocation diffusion, lead to a greater spreading of the disease

Epidemiology

The branch of medical sciencee concerned with the incidence, distribution, and control of diseases

Pandemic

A disease that prevails globaly and affects a very high proportion of the population

Mobility

A general term covering all types of movement from one place to another

Cyclical movement

A regular journey that begins at a home base and returns to the exact same place.

Periodic movement

Time away from the home base; don't necessarily return to the same place.

Net migration

The difference between the number of immigrants and the number of emigrants

Net in-migration

When the number of immigrants exceeds the number of emigrants and the net migration is positive

Net-out-migration

If the number of emigrants exceeds the number of immigrants and the net migration is negative

Reasons for migration

Economic opportunity, cultural freedom, and environmental comfort.

Intaregional Migration

Movement within a region

Interregional Migration

Movement from one region to another

Migration Transition

Change in migration patterns in a society caused by industrialisation, population growth, and other social and economic changes that also produce the demographic transition

Stage 1 MTM

High daily or seasonal mobility in search of food

Stage 2 MTM

High international emigration and interregional migration from rural to urban areas

Stage 3 MTM

High international emigration and interregional migration from rural to urban areas

Stage 4 MTM

Same as Stage 3: high international immigration and intraregional migration from cities to suburbs

17th and 18th Centuries

U.S. Immigration from Europe and Sub-Saharan Africa

Mid-Nineteenth to Early Twentieth Century

U.S. Immigration from Ireland, Germany, Scandinavia, and Southern and Eastern Europe

Late 20th to Early 21st Century

U.S. Immigration from Asia and Latin america

Ravenstien's Laws

-Most migrants travel only a short distance

-The number of migrants to a destination declines as the distance they must travel increases.

-Migrants who move longer distances tend to choose major cities

-Every migration flow generates a return or counter flow.

-Families are less likely to make international moves than young adults.

-Men migrate long-distances.

-Women migrate shorter distances but more often than men.

Consequences of migration

Demographic Consequences

-Occurs when migrants change the basic structure of a population

Economic Consequences

-Increase in cost and building of health care, education, public services, and housing

-Lost tax revenue from illegal migrants.

Social Consequences

-Better cultural understanding.

-Conflict among groups

Migrant Workers

These immigrants serve a useful role in Europe, taking low-status and low skill jobs that local residents won't accept

Refugee

Refugee: "a person who has a well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group, or political opinion."

Asylum seeker

Someone who says he or she is a refugee, but whose claim has not yet been definitively evaluated.
