Unit 2 Vocab - Population Flashcards
Activity Space
The area in which an individual moves about as he / she pursues regular, day-to-day activities.
Agricultural / Neolithic Revolution
The domestication of plants and animals meant that human beings created larger and more stable food sources, causing more people to survive and live longer.
AIDS (Acquired Immune Deficiency Syndrome)
A disease that began in central Africa during the late 20th century and spread to many across the continent before the end of the century.
Arable Land
Land that is suited for agriculture.
Arithmetic Rate
A steady rate of change (ex. food supplies).
Arithmetic / Crude Density
The total number of people divided by the total land area.
Awareness Space
May be limited so that one’s knowledge of opportunity locations beyond the normal activity space is minimal (ex. poverty).
Birth Rates
The number of babies born per year per 1000 people.
Carrying Capacity
The number of people an area can support on a sustained basis.
Chain Migration
A stream of people out of an area as first movers communicate with people back home and stimulate others to follow later.
Circulation
A short-term, repetitive movement that occurs on a regular basis.
Critical Distance
The distance beyond which cost, effort, and means strongly influence willingness to travel.
Crude Birth Rate
The number of live births in a given year for every 1,000 people in a population.
Crude Death / Mortality Rate
The number of deaths in a given year for every 1,000 people in a population.
Death Rates
The number of deaths per year per 1,000 living people.
Demographic Momentum
The phenomenon that once a large base of young people grows beyond child-bearing age, the overall population will gradually decline.
Demographic Transition Theory
The theory that population patterns vary according to different levels of technological development, but all countries go through the same four stages.
Demographic Transition Theory STAGES
Stage 1: Low Growth
Stage 2: High Growth
STage 3: Moderate Growth
Stage 4: Low Growth
Demographic Equation
A summary of the population change over time in an area by combining both natural change and net migration.
Demography
The study of population.
Density
The number of people who live in a defined land area.
Dislocation
People who are forced from their homes due to ethnic strife, war, or natural disasters.
Distance Decay
The decline of an activity or function with increasing distance from its point of origin.
Dot Maps
A map where each dot represents a certain number of people.
Doubling Rate
The length of time needed to double a population.
Emigration
The migration FROM a location.
Endemic
A disease regularly ocurring within an area or community.
Epidemiologic Transition / Mortality Revolution
The drop in death rates that became significant in the mid-19th century.
