AP HUG Unit 2 Flashcards
Demography
The study of population characteristics. “demo”=population/people, “graphy”=writing
Population Distribution
How people are spread out through an area.
Physical Factors Influencing Population
Factors that influence where and how many people live in an area that are based on geographic/environmental strengths and weakness
Ecumene
The portion of Earth’s surface settled by humans
Human Factors Influencing Population
Factors that influence where and how many people live in an area that are based on human causes
Population Concentration
Where people are clustered
Population Distribution at a Global Scale
Where people are spread out across the globe
Population Distribution at a National Scale
Where people are spread out across a nation
Population Distribution at a Local Scale
Where people are spread out across a local area
Population Density
The amount of people over the amount of land in an area
Arithmetic Density
People per every unit every land in an area
Physiological Density
People per every unit of arable land in an area
Agricultural Densitty
Farmers per every unit of arable land in an area
Arable Land
Land that can be used for agriculture
Economic Implications
Impacts that are related to economic effects. In this context, impacts from density and distribution
Political Implications
Impacts that are related to politics. In this context, impacts from density and distribution
Social Implications
Impacts that are related to social effects. In this context, impacts from density and distribution
Environmental Implications
Impacts that are related to the environment. In this context, impacts from density and distribution
Carrying Capacity
The amount of people/animals a certain area can sustain without significant damage.
Overpopulation
Having a population that exceeds the carrying capacity of an area.
Infrastructure/Urban Services
Basic services used in the operation of a society
Ethnicity
Someones race, culture, or demographic.
Age-Sex Composition
These are factors that show you how old and what genders an area has
Sex Ratio
The percentage of males to females
Cohort
Different age groups on a population pyramid
Baby Boom
An explosion in the number of births
Baby Bust
A slowing of population growth after a baby boom
Echo
A spike or drop in a population as a result of an earlier spike or drop.
Dependency Ratio
The ratio of working-age people to the dependent population
Potential Workforce
People between the age of 15 and 65
Dependent Population
People above the age of 65 or below 15
Census
A survey that gathers data about population and demographics
Demographic Momentum
This is the tendency for growing population to continue growing after a fertility decline because of their young age distribution
RNI
Rate of Natural Increase. The rate of growth for a population excluding any outside factors. Just CBR/CDR.
Population Doubling Time
The amount of time it takes for a population to double
ZPG
Zero Population Growth. People are dying at the same rate that they are being born
CBR
Crude Birth Rate. Total births per 1000 people
CDR
Crude Death Rate. Total deaths per 1000 people
Demographic Transition Model (DTM)
A model that predicts and explains population growth
Stage 1 (DTM)
This is the first stage of the demographic transition model. It is characterized by high fluctuating CBR and CDR.
Stage 2 (DTM)
This is the second stage of the demographic transition model. It is characterized by a declining CDR and a fairly stable CBR
Stage 3 (DTM)
This is the third stage of the demographic transition model. It is characterized by a decline in the CDR’s rate of decline and a declining CBR.
Stage 4 (DTM)
This is the fourth stage of the demographic transition model. It is characterized by a low fluctuating CBR and CDR
Stage 5 (DTM)
This is theorized to be the fifth stage of the demographic transition model. There are many different ideas of what this will look like, such as CBR and CDR stabliizing, CDR surpassing CBR, ect.
Expansive Population Pyramid
A population pyramid that has a wide base and a small top
