What is the definition of Demography?
The scientific study of population characteristics.
How many confirmed stages are there in the DTM?
4
What is population density?
A measurement of population per unit area or unit volume.
What are the parts of a population pyramid?
Age, gender, and percent of population
How many countries are in stage 1?
0
What is the Medical Revolution?
Medical technology invented in Europe and North America that is diffused to the poorer countries of Latin America, Asia, and Africa. Improved medical practices have eliminated many of the traditional causes of death in poorer countries and enabled more people to live longer and healthier lives.
What are the demographic characteristics in the DTM?
Crude Death Rate and Crude Birth Rate
What is Arithmetic Density?
Total population/land area (Shows physical crowding)
What is the age range of the working class?
15-64
In the US, why is the East Coast more populated?
What is the definition of Doubling Time?
The number of years needed to double a population, assuming a constant rate of natural increase.
In stage 2, why does the CDR drop?
Better medical understanding and agricultural technology improves.
What is Agricultural density?
Number of farmers/arable land area (relative level of development.
Which stage looks like a typical pyramid?
Stage 2
What affects population distribution?
human factors (economic, cultural, historical, and political) and physical factors (climate, land forms, topography, soil)
What is the definition of Ecumene?
The portion of Earth's surface occupied by permanent human settlement.
In which stages does the CBR fluctuate?
Stage 1 and stage 4
What is Physiological Density?
Total population/arable land area (The land to support the population)
In a stage 4 population pyramid, why are the sides bumpy or curved?
Having children becomes a trend, for example the baby boomers generation greatly increased the birth rate because it became a trend.The birth rate fluctuates because of the trends which then leads to bumpy or curved sides.
South Asia
What is the definition of Epidemiology?
The branch of medical science concerned with the incidents, distribution, and control of diseases that are prevalent among a population at a special time and are produced by some special causes not generally present in the affected locality.
How does the Epidemiological transition affect the rates on the DTM?
With immediate diseases, there is a high birth rate due to the need to replace so many people. As more degenerative diseases emerge and immediate diseases go away, the death rate and birth rate drop.
How does knowing Density help us?
It aids in our comprehension of settlement dispersion and allows us to compare distribution access various locations.
Why do the population pyramids change as the country develops?
The base gets smaller because having a baby is a trend, not a necessity. The top and middle parts gets wider because more old people survive but it still ends at a sharp point.
Why is global population increasing?
Increasing numbers of people surviving to adulthood, increase in human lifespan, increasing urbanization, and accelerating migration
