Agricultural density
The ratio of the number of farmers to the amount of arable land, indicating the efficiency of agricultural production in a region.
arithmetic density
The total number of people divided by the total land area, measuring population distribution in a region.
asylum seekers
Individuals who flee their home country due to persecution or fear of persecution and seek protection in another country.
brain drain
The emigration of highly trained or qualified individuals from one country to another, often resulting in a loss of skilled labor in the originating country.
CBR
The crude birth rate (CBR) is the number of live births per 1,000 people in a given year, used to measure population growth.
CDR
The crude death rate (CDR) is the number of deaths per 1,000 people in a given year, used to assess mortality rates in a population.
IMR
The infant mortality rate (IMR) is the number of deaths of infants under one year old per 1,000 live births in a given year, reflecting the health of a population.
TFR
The total fertility rate (TFR) is the average number of children that would be born to a woman over her lifetime, given current birth rates and assuming she survives through her childbearing years.
NIR/RNI
The natural increase rate (NIR), also known as the rate of natural increase (RNI), is the difference between the number of live births and the number of deaths in a population over a specific period, typically expressed as a percentage of the total population.
carrying capacity
is the maximum population size that an environment can sustain indefinitely without degrading the environment, based on available resources.
chain migration
is a process where migrants from a particular town or region follow others from that area to a new destination, often due to family or community ties
circular migration
is the temporary movement of individuals between their home and host locations, often for work or education, with the intention of returning
Cohort
Is a group of individuals who share a common characteristic typically used in demographic studies to track changes overtime
dependency ratio
Is a measure of the ratio of dependence (people younger than 15 or older than 64) to the working age (ages 15-64) used to assess the economic burden of the productive population
ecumene
The inhabited areas of the earth were people live, contrasting the uninhabited region
guest worker
A person who is permitted to work in a country temporarily often filling, labor shortages in sector, such as agriculture or construction
hollow core
A model explaining urban development where cities population density decreases at its center leading to an area of low occupancy within the urban space
internal migration
The permanent movement of people within a country often from ruled to urban areas in search of better economic opportunities or living conditions
internally displaced person
A person who has been forced to flee their home but remains within their countries borders often due to conflict persecution or national disasters
intervening obstacles
factors that hinder migration such as physical barriers or legal restrictions that prevent people from moving to their desired destination
intervening opportunities
Factors that encourage migration by providing advantages or benefits along the migration route, making certain destinations, more attractive
mathusian theory
Theory proposed by Thomas Mathus, that growth outpace food production leading to the widespread famine and society struggles
neo mathusians
Advocates of a revised enthusiast theory that emphasizes the potential for overpopulation, and it affects on resources arguing the population growth can lead to environmental degradation and food scarcity
physiological density
The number of people per unit area of arable land indicated population pressure on agricultural resources
population density
population distribution
The spatial arrangement of people across Earth's surface.
refugees
People forced to flee their country due to conflict, persecution, or disasters, unable to return safely.
remittance
Money sent by migrants to family members in their home country, often supporting the local economy
step migration
Migration that occurs in stages, such as moving from a village to a town and then to a city.
transhumance
The seasonal movement of livestock and people between highland and lowland pastures
transnational migration
When people move across international borders while maintaining connections to their home country.
voluntary migration
When people choose to move, often for economic opportunities or better living conditions.
Census
A systematic process of collecting, analyzing, and interpreting data about a population, typically conducted every ten years to gather demographic information.
Clustering
The process of grouping individuals or items in close proximity to one another, often observed in population distribution patterns.
dispersal
The spatial distribution of individuals within a population, which can be uniform, random, or clumped.
distance decay
The principle that as the distance between two places increases, the likelihood of interaction between them decreases, often affecting cultural and economic exchanges.
friction of distance
The concept that distance creates a barrier to interaction, affecting the flow of people, goods, and information between locations.
geographic system
A framework that encompasses the interactions and relationships between various geographic elements, including physical, biological, and human systems.
large scale maps
Maps that show a small area with a high level of detail, typically used for urban planning or local navigation.
meridian of longitude
An imaginary line that runs from the North Pole to the South Pole, used to measure degrees of east or west from the Prime Meridian.
parallel of latitude
An imaginary line that runs parallel to the equator, used to measure degrees of north or south from the equator.
place
A specific location defined by its physical and human characteristics, often used in geography to describe the uniqueness of a location.
reference maps
Maps that show the location of various features such as roads, boundaries, and landmarks, often used for navigation and orientation.
scale of analysis
The level of detail or geographic extent used in analyzing data, which can range from local to global perspectives in geographic studies.
site
The physical characteristics of a specific location, including its terrain, soil, and climate, which contribute to its uniqueness.
situation
The location of a place relative to its surroundings and other locations, including its accessibility and connections to other areas.
small scale maps
maps that depict large areas with less detail, often used to show broader geographic trends.
spatial association
The degree to which two or more phenomena are related to each other in space, often used to identify patterns or correlations in geography.
sustainability
The ability to meet present needs without compromising the ability of future generations to meet their own needs, often involving environmental, economic, and social considerations.
Thematic maps
maps that focus on a specific theme or subject, such as population density, climate, or economic activity, rather than on geographic features.
time space compression
The phenomenon where the relative distance between places decreases due to advancements in transportation and communication technology, making it easier to connect and interact across long distances.
toponyms
Names given to places or features, reflecting cultural, historical, or geographical significance.
