|
Forced Migration

For human or nature reasons.
|
|
population distribution
|
uneven pattern of human settlement
|
|
branch of medical science concerned with the incidence, distribution, and control of disease that affects large numbers of people.
|
epidemiology
|
|
Neo-Malthusian
|
Theory that builds upon Malthus’ thoughts on overpopulation. Takes into count two factors that Malthus did not: population growth in LDC’s, and outstripping of resources other than food
|
|
migration
|
movement of people from place to place
|
|
population geography
|
a division of human geography concerned with spatial variations in distribution, composition, growth, and movement of population
|
|
Cumulative (compound) growth of a population over a given period of time
|
Exponential Growth
|
|
the formula that calculates population change. births - deaths (+ or -) net migration
|
demographic equation
|
|
J-curve
|
This is when the projection population show exponential growth. This is important because if the population grows exponential resource use will go up exponentially and so will our use as well as a greater demand for food a
|
|
Population Density
|
The average number of people per square km.
|
|
Deomgraphic transition model: Stage 5
|
DecliningBirth rate=very lowDeath rate=lowNatural Increase=negative population growthExamples-Germany, Russia, Italy, Japan
|
|
population pyramid
|
a model used in population geography to show the age and sex distribution of a particular population
|
|
the time when human beings first domesticated plants and animals and no longer relied entirely on hunting and gathering
|
agricultural revolution
|
|
Overpopulation
|
The number of people in an area exceeds the capacity of the environment to support life at a decent standard of living.
|
|
Sex ratio
|
The number of males per hundred females in the population
Depends on birth and death rates, immigration. Men have higher death rates but also higher birth rates. Immigration usually means more males because they can make the journey.
|
|

Shows population density on a map by shading.
|
|
Dependency Ratio
|
The number of people dependent on the working population.

|
Total Fertility Rate
|
average number of children a woman will have throughout her child bearing years

|
|
The total number of people divided by the total land area
|
Arithmetic Density
|
|
the percentage by which a population grows in a year.
|
natural increase rate
|
|
child mortality rate
|
number of deaths of children ages 1-5 per 1,000 children
|
|
the ratio of the number of farmers to the amount of arable land.
|
agricultural density
|
|
Zero Population Growth
|
A decline of the total fertility rate to the point where the natural increase rate equals zero.
|
|
Population composition
|
the number of women and men and their ages
|
|
Epidemiological Transition model
|
This is a distinctive cause of death in each stage of the demographic transition. This explains how a countries population changes so dramatically.
|
|
the total number of deaths in a year for every 1,000 people alive in the society
|
crude death rate
|
|
Crude Birth Rate (CBR)
|
the number of live births per year per 1,000 people

|
Moving to another country.

POPULATION
|
total number of people in an area.

chain migration
|
the migration event in which individuals follow the migratory path of preceding friends or family members to an existing community
|
|
A bar graph representing the distribution of population by age and sex
|
Population Pyramid
|
|
helps predict future problems within population such as overpopulation or underpopulation of a certain race or ethnicity (predicts the future of an area of the world)

"push-pull" theory
|
a theory demographers use
to explain immigration:
people migrate because things
"push" them to leave
and the hope for better living conditions "pulls" people to a country
|
|
exponential growth
|
growth that occurs when a fixed percentage of new people is added to the population each year. Exponential growth is compound because the fixed growth rate applies to the an ever-increasing population

author of EASSAY ON THE PRINCIPLE OF POPULATION (1798) who claimed that population grows at an exponential rate while food production increases arithmetically, and thereby that, eventually, population growth would out place food production

|
Carrying capacity
|
This is the population level that can be supported, given the quantity of food, habitat, water and other life infrastructure present. This is important because it tells how many people an area will be able to support.
