As we finished the previous unit, we headed into the next unit of this semester, which is going to dig deeper into a previous unit we looked at in quarter one. Here are some of the notes we took today:
Key Questions:
Where is the worlds population distributed?
Why is global population increasing?
We does population growth vary among regions?
Why do some regions face health threats?
Population Concentrations
2/3 of the worlds population are clustered in 4 regions
East Asia
South Asia
Southeast Asia
Europe
Site and Situation of population clusters
-Low lying areas with fertile soil and temperate climate
-Near ocean or river that is near to ocean
-Sparsely populated regions
-Humans avoid clustering in certain physical environments:
>>dry lands
>>wet lands
>>cold lands
>>high lands
Places considered too harsh for occupancy have diminished over time
places of permanent human settlement are termed the ecumene
Population Density
Density can be compute in up to three ways for a place
Arithmetic density
Total number of objects in area/ land area
Physiological density
number of people supported by a unit area of arable land
population/ arable land area
Agricultural Density
Ratio of number of farmers to amount of arable land
population of farmers/ arable land area
Components of population growth
Crude birth rate
Crude death rate
Rate of natural increase
