1. Plot the population as a function of time. What are the dramatic features of this graph and how might they be accounted for?
- The graph shows a steady increase in population over time, with no sharp declines or plateaus.
- This reflects consistent population growth due to factors like improved healthcare, higher birth rates, and immigration.
2. Plot the area as a function of country's population. What are the dramatic features of this graph and how might they be accounted for?
- The graph shows that as population increases, the area also increases, but not linearly.
- The rate of area expansion slows over time, indicating that later territorial acquisitions were smaller or that population density increased in existing areas.
3. Plot the population as a function of area. What are the dramatic features of this graph and how might they be accounted for?
- The graph shows that population grows faster than area, especially in later decades.
- This indicates increasing population density, likely due to urbanization, technological advances in agriculture, and migration to developed regions.
4. Plot the rate of increase of population as a function of time. What are the dramatic features of this graph and how might they be accounted for?
- The graph shows fluctuations in the rate of population growth, with peaks during periods like the post-WWII baby boom and dips during economic downturns or wars.
- These changes reflect societal, economic, and policy-driven shifts affecting birth rates, death rates, and immigration.
