Unit 2 Vocabulary Flashcards
Topic 1: Physical Factors
Physical factors are physical characteristics that facilitate population clusters; examples include coasts, rivers, oceans, waterways, transportation, natural resources, etc.
Topic 1: Human Factors
Human factors are human characteristics that facilitate population clusters; examples include trade, commerce, cultural, economic, emotional, historical, economic stability, etc.
Topic 1: Population Cluster
A dense concentration of people in a specific geographic area; usually forms based on physical or human factors in an area.
Topic 1: Population Density
Population density is the amount of people in an area.
Topic 1: Arithmetic Population Density
Formula: Total Population/Total Amount of Land
This shows how many people live in each unit of land; if the number is high, then there are more people living in each unit of land/if the number is low, then there are fewer people living in each unit of land.
Topic 1: Physiological Population Density
Formula: Total Population/Total Amount of Arable Land
This shows how much food we need to produce from one unit of arable land; if the number is high, we need to produce more food, but if the number is low, then we don’t need to produce as much.
Topic 1: Agricultural Population Density
Formula: Amount of Farmers/ Total Amount of Arable Land
This shows us how advanced technology is in an area or how efficient a society is at producing food; if the number is high, then more manual labor is in an area, and less technology is used.
Topic 1: Population Pressure
Population pressure refers to the stress or strain on a region’s resources, infrastructure, and environment due to a growing population.
Ex: In parts of India, there has been massive population growth, putting stress on water resources, so groundwater is being depleted faster than it can be replenished.
Topic 2: Provision of Services
Refers to supplying or delivering services to meet the needs or demands of individuals; falls under the tertiary sector of the economy.
Topic 2: Natural Resources
Materials or substances that occur in nature and can be used by humans for economic gain, development, or survival; renewable or non-renewable resources.
Topic 2: Carrying Capacity
The amount of people that the environment can support without damaging the environment; will see a depletion of resources and won’t be able to meet the needs and wants of future generations if it exceeds.
Topic 2: Population Density
The amount of people in an area.
Topic 2: Population Distribution
The spread of people in an area.
Topic 2: Pros and Cons due to population Density- Political
Pros:
- Larger urban areas will have more political power
- The government will not have to provide more services over a long distance due to the clustering of people
Cons:
- Rural areas will have less political power
- As population density for rural areas increases, urban areas political power will shrink
Topic 2: Pros and Cons due to population Density- Economic
Pros:
- Urban areas will have more variety of job opportunities
- More goods and services for urban areas
- Rural areas have less cost of living
Cons:
- Will have to compete with more people in the job market
- Urban areas have higher costs of living
- Rural areas have less goods and services
Topic 2: Pros and Cons due to population Density- Social
Pros:
- Rural areas have a larger family size
- Urban areas will not have to travel far for services
Cons:
- Urban areas have a smaller family size
- People in rural areas will have to travel farther for services
- Urban areas lack space
Topic 2: Pros and Cons due to population Density- Environmental
Pros:
- Rural areas are more likely to have more green space
Cons:
- Urban areas lack green space due to the constant evolution of building infrastructure such as roads and buildings
Topic 2: Urban Sprawl
The spread of urban development from an urban area into undeveloped land.
Topic 3: Age Structure
Placed on the y-axis of a population pyramid; 0-14 are the pre-reproductive years, 15-44 are the reproductive years, and 45-100+ are the post-reproductive years
Topic 3: Sex Ratio
Sexes are placed on the x-axis; the left side of the x-axis is for males and the right side is for females; should be close to 50:50 for any given society
Topic 3: Population Pyramid
A pyramid is used to chart the demographics of a country’s sex percentage in a certain age range.
Topic 3: Markets for goods and services
More variety of goods and services will be located in urban areas where more people will be creating these, while rural areas will have basic goods and services, but will have to travel far for these other goods and services.
Topic 3: Total Dependency Ratio
The Dependency ratio compares the number of people not in the labor force to the number who are; as you progress through the demographic transition model, life expectancy increases, and then the total dependency ratio also increases.
[(# of children(0-14) + # of adults(65+))/working age population] * 100
- High #: Working people have a greater burden supporting the non-working population
Topic 3: Child/Youth Dependency Ratio
[# of children(0-14)/# of adults(16-64)] * 100
- High #: Need more schools or daycare facilities
Topic 3: Elderly Dependency Ratio
[# of elderly(65+)/# of adults(16-64)] * 100
- High #: More retirement homes or healthcare facilities
Topic 4: Crude Birth Rate/Population Growth
The total number of births in a year for every 1000 people alive in a society leads to population growth.
Topic 4: Crude Death Rate/Population Decline
The total number of deaths in a year for every 1000 people alive in a society leads to a population decline.
Topic 4: Total Fertility Rate (TFR)/Fertility
The average number of children a woman will have. Fertility is a person’s ability to conceive children.
Topic 4: Infant Mortality Rate(IMR)/Mortality
The total number of deaths under one year of age in a year for every 1000 live births. Mortality is the state of being destined to die at one point.
Topic 4: Natural Increase Rate (NIR)
Aka. Rate of Natural Increase
The percentage by which the population grows in a year.
NIR= Crude Birth Rate-Crude Death Rate
Topic 4: Doubling Time
The amount of time it takes for a population to double in size. Formula: 70/growth rate
Topic 4: Migration/Migration Rate
Migration is the movement of people from one location to another. It can either increase or decrease a country’s NRI; causes of this can include economic opportunities, push or pull factors, etc. Migration is the rate at which one leaves or enters a country.
Topic 5: Stage 1
(Pre-reproductive years)
DTM: Birth Rate and Death Rate is high, and very low NIR; lacks sanitation, medicine, contraceptives, mainly agricultural based society
Epidemiological: Pestilence, Famine, and Death- animal attacks, parasitic and infectious diseases, food shortages, dirty water, etc.
Topic 5: Stage 2
(Reproductive years)
DTM: High birth rate, falling death rate, and increasing NIR; more urbanization and food surplus, advancements in medicine and knowledge of medicine, and emigration
Epidemiological: Receding Pandemics- improved standard of living, increased food production, nutritious food, and sanitation.
Topic 5: Stage 3
(Reproductive years)
DTM: Slowly falling birth rate and continuous falling death rate, moderate/stable NIR; more gender roles, manufacturing and tertiary sector of jobs
Epidemiological: Degenerative Diseases- diseases that get worse over time; ex. heart attacks, cancer, etc.
Topic 5: Stage 4
(Reproductive years)
DTM: Low birth and death rates, stable high NIR; more economic opportunities for women, and education and jobs in the tertiary sector.
Epidemiological: Fighting Degenerative Diseases- medical advancements, longer life expectancies, improved diet and lifestyle.
Topic 5: Stage 5
(Post-reproductive years)
DTM: Low birth rate and low death rate, decreasing NIR; post-reproductive years, population decline
Epidemiological: Reemergence of Infectious Diseases- increased poverty, urbanization, and globalization; ex. Covid 19
Topic 5: Immigration
A migrant immigrating into a country; NRI will increase of the country.
Topic 5: Emigration
A migrant emigrating out of a country; NRI will decrease of the country.
