UNIT 2 Flashcards
What are four physical factors that influence the distribution of human populations?
Climate, weather patterns, landforms, bodies of water,& natural resources
Identify four human factors that influence the distribution of human populations.
Economic, cultural, historical, and political factors
Pull Factors
Economic: A variety of opportunities/services
Social: A community that is open and welcoming to different cultural groups
Historical: Influenced, historical events, political boundaries, and empires
Political: A stable political environment where people feel safe and supported
What is the difference between dispersed and clustered places?
Places that are dispersed have their population, buildings, or other features spread out over a geographic area. Clustered places have little to no space between the different features.
Describe the difference between population distribution and density.
Distribution is the spread of people in an area, while density is the number of people in an area
Arithmetic
Total population/total amount of and, a commonly used metric to show how densely populated an area is
Physiological
Total population/total amount of arable land Measures the pressure that society puts on the environment of the population
Agricultural
Number of farmers/total amount of arable land. Shows the level of efficiency of agricultural production in an area
Explain why the physiological density is a more accurate measure of population pressure than the arithmetic density.
The physiological density takes into account the relationship between the population and arable land, giving insight into the impact that feeding the population will have on agricultural lands
Explain why a region may have a low agricultural density.
More productive agricultural practices and techniques may be used in the region. More machines and advanced equipment for the production of agricultural products are also likely to be used
What is the difference between population distribution and population density?
Population distribution shows where people live. Population density shows how many people live in specific areas.
Impact of Population Density & Distribution
Political: Areas that are more densely populated tend to have greater political representation compared to areas that have a low density and are sparsely populated
Economic: Places with a higher density often have more economic and social opportunities. Places with lower population density are less likely to have higher taxes and high cost of living
Social: More densely populated areas often have more education, healthcare, and social offerings for residents. Areas with a lower population density tend to lack specialized services but have a more communal feel
Environmental: Densely populated areas are more likely to expand outwards, leading to urban sprawl. Less densely populated areas are more likely to have more green spaces and open areas
Identify two environmental problems associated with higher population densities.
Pollution and depletion of resources
Define carrying capacity
The number of people that can be supported without damaging the environment
Identify six different demographic characteristics
Age, gender, ethnicity, educational attainment, income, and occupation
What do the Yaxis and Xaxis represent in a population pyramid?
The TheYaxis represents age ranges or cohorts, while the Xaxis represents the number of people in society
Identify the three different categories based on people’s stages of life
1)Pre-reproductiveyears(0–14) 2)Reproductiveyears(15–44)
3)Post-reproductiveyears(45andup)
Describe two different ways in which population pyramids can be used to understand society better.
1)Governments can use them to see what will happen with their tax base in the future
2)A state can use them to better understand what services they need to provide their residents
How do you find the sex ratio of a society?
(Malebirthsinasociety/female births in society)*100
Describe how you interpret sex ratio data
If the number is above 100, it means there are more male births in society. If it is below 100, it means there are more female births.Ifitis100, the ratio of births is the same
Dependency ratio
((Childrenaged0to14)+(Peopleaged65+)/(Workingagepopulation))*100
Child dependency ratio
((Childrenaged0to14)/(Workingagepopulation))*100
Elderly dependency ratio
((Peopleaged65+)/(Workingagepopulation))*100
What does a high dependency ratio mean?
There will be a larger burden on society since the working population will have to pay more taxes to support the number of people who are not working
Crude Birth Rate(CBR)
Total number of live births in a year for every 1,000 people that lives in society
Crude Death Rate(CDR)
The total number of deaths in a year forevery1,000 people alive in a society
Natural Increase Rate/Rate of natural Increase
The percentage by which a population grows in a year.(NIRorRNI)=CBR-CDR
doubling time
The amount it takes a population to double
TotalFertilityRate(TFR)
The average number of children women will have
Infant Mortality Rate(IMRP)
The total number of deaths in individuals under one year of age in a year for every1,000 live births
Whatisthereplacementrateofasociety?
ATFRof2.1
Identify three things that could reduceasociety’sIMR, TFR, or CDR.
1) More opportunities for women in society
2)Better access to healthcare services
3)Investment in education for both men and women
Explain what happens to society’s growth rate as economic development occurs
Women gain more access to different jobs and services insociety, which causes the RNIto decreases women spend more time getting educated, working,and participating in society
Describe why economies that are agriculture-based often have a higher RNI
Larger families in these regions are often economic assets since children can help out on the farm and help support the family
What are two things the government can do to impact the population dynamics of society?
1)Restrict immigration
2)Implementpro/antinatalistpolicies
3)Provide more opportunities for women and men in society
Stage 1 of the DTM
High birth and fertility rate. High death rate and child mortality rate. little population growth. Subsistence farming. Life expectancy is low, medical field is very low. The role of women is traditional - caretakers/mothers. seasonal migration for food and flocks. No one is in this demographic anymore.
Stage 2 of the DTM
Very high birth rate, need more kids to farm. Rapid decrease in death rate. The rapid increase in population growth. The main economic focus is agriculture for trade. Life expectancy is increasing as there is increasing sanitation. Women are still in traditional roles. Migration patterns are from rural to urban. Afghanistan, Angolia, Sudan
Stage 3 of the DTM
The birth rate is rapidly decreasing, no need for as many kids. The death rate is decreasing. Population grows at a slower rate. The economic focus is manufacturing. Life expectancy is increasing, and health care is better. More women in the workforce. Increase in rural to urban migration. Mexico, Vietnam.
Stage 4 of the DTM
The birth rate is flat and bottoms out. The death rate is flat and bottoms out. Zero population growth. The economic focus is on service industries. Highest life expectancy, specialized doctors, and best healthcare. Women are economically and socially empowered. Surbaban living and more immigration. China and USA
Stage 5 of the DTM
Very Low CBR / Increasing CDR / Declining NIR
Demographers predict a possible stage 5 of the demographic transition for some developed countries.
After several decades of very low birth rates, a stage 5 country would have relatively few young women aging into childbearing years. As those in the smaller pool of women each choose to have fewer children, birth rates would continue to fall even more than in stage 4.
The theoretical Stage 5 is not included in the model above.What are two unique characteristics of Stage 5?
1)CDR goes above the CBR, causing the population to decrease
2)The majority of the population is generally in their post-reproductive years
