Unit 2: Population- Migration and Dispersion
|(Population Pyramid) Used to show development, significant events in countries, etc.
|The population level that can be supported, given the quantity of food, habitat, water
|Population of various age categories in an age-sex population pyramids. Used to show the stage of a country in the Demographic Transition Model
|The tendency for growing population to continue growing after a fertility decline because of young age distribution
|Demographic Transition Model
|Stage 1: Low Growth Stage 2: High Growth Stage 3: Moderate Growth Stage 4: Low Growth Stage 5: Zero/Negative Growth (not officially a stage)
|Number of people who are too young or too old to work compared to number or people who can work
|Number of years it takes to double a population
|Proportion of Earth's surface occupied by permanent human settlement.
|Infant Mortality Rate
|Annual number of infant deaths compared to live births
|In a population pyramid, it shows exponential growth.
|Geographer that first started worrying about overpopulation. People reproduce geometrically while food is produced arithmetically.
|Natality (Crude Birth Rate)
|Ratio of live births in an area to the population of that area
|Relationship between the number of people on Earth and the availability of resources
|Arrangement of a feature in space
|Sudden increase in population
|Predicts the future population of an area or world
|Rate of Natural Increase
|Percentage by which a population grows in a year
|Standard of Living
|Refers to the quality and quantity of goods and services available to people and the way they are distributed within a population
|Providing the best outcomes for human and natural environments both in the present and the future
|refers to the sharp decrease in a region's population
|Zero Population Growth
|Crude birth rate = crude death rate, thus natural increase is zero
|When one family member/group migrates to a country and other groups follow shortly after
|Trends in migration that have a clear cycle
|When people are removed from their counties and forced to live elsewhere because of war, natural disaster, government instability
|Predicts that the optimal location of a service is directly related to the number of people in the area and inversely related to the distance people must travel to access it
|Permanent movement within a country
|Environmental or cultural feature that helps migration
|Permanent movement from one county to a different country within the same continent.
|Permanent movement from one region of a country to another region
|Permanent movement from rural area to city
|Factors that induce people to leave or come to a location
|Seasonal migration of livestock between mountains and lowland pasture areas
