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
