Population Density: What is the spatial distribution of people in South Asia and China compared to global
population rates?

Critical Issues in Population Geography
• More people are alive today than at any other time in human history
• The world’s population increased at a faster rate during the second half of the twentieth century than ever before.
• Virtually all population growth today occurs in less developed countries (LDCs)
![Page 9: Chapter 2: Population](https://reader031.fdocuments.net/reader031/viewer/2022020200/56813283550346895d991eaf/html5/thumbnails/9.jpg)
Ecumenes: A portion of the earth’s surface occupied by permanent human settlement.
• What climates do people avoid?
-cold areas (polar regions)-high areas (Mts, except for
the Andes and some areas of Africa)
- arid areas too dry for farming (deserts)
-wet areas (rainforests, flooded basins)

Where Is the World’s Population Distributed?
• Population concentrations– Two-thirds of the world’s population are in
four regions:• East Asia• South Asia• Europe• Southeast Asia
![Page 11: Chapter 2: Population](https://reader031.fdocuments.net/reader031/viewer/2022020200/56813283550346895d991eaf/html5/thumbnails/11.jpg)

Where Is the World’s Population Distributed?
• Population density: # of people occupying land can be computed in several ways– Arithmetic density: total number of people
divided by total land area– Physiological density: total number of
people divided by arable land area– Agricultural density: total number of
farmers divided by arable land area
![Page 13: Chapter 2: Population](https://reader031.fdocuments.net/reader031/viewer/2022020200/56813283550346895d991eaf/html5/thumbnails/13.jpg)

Where Has the World’s Population Increased?
• Natural increase rate– The percentage by which a population grows in a
year
• Crude birth rate (CBR)– The number of births per 1,000 population
• Crude death rate (CDR)– The number of deaths per 1,000 population
• Doubling time– The number of years needed to double a population
![Page 16: Chapter 2: Population](https://reader031.fdocuments.net/reader031/viewer/2022020200/56813283550346895d991eaf/html5/thumbnails/16.jpg)

Where Has the World’s Population Increased?
• Fertility– Total fertility rate (TFR): the average # of
children a woman will have during childbearing years; 2.6 for the world
• Mortality– Infant mortality rate (IMR): # of infant
deaths under 1 year compared with total live births
– Life expectancy: average number of years one can expect to live
![Page 18: Chapter 2: Population](https://reader031.fdocuments.net/reader031/viewer/2022020200/56813283550346895d991eaf/html5/thumbnails/18.jpg)

• Notice that places with high TFRs tend to have high IMRs and that places with low TFRs have low IMRs.

Why Is Population Increasing at Different Rates?
• Demographic transition– Four stages
• Stage 1: Low growth– Agricultural revolution
• Stage 2: High growth– Industrial Revolution
• Stage 3: Moderate growth• Stage 4: Low growth
– Zero population growth (ZPG)

Why Is Population Increasing at Different Rates?
• Population pyramids– A bar graph showing a place’s age and sex
composition– Shape of the pyramid is determined mainly by the
CBR– Age distribution
• Dependency ratio: number of people too young or too old to work (0-14, 65+)
– Sex distribution• Sex ratio: number of males per hundred females

Why Is Population Increasing at Different Rates?
• Countries are in different stages of the demographic transition– Three examples:
• Cape Verde = High growth– Stage 2 since the 1950s
• Chile = Moderate growth– Stage 3 since the 1960s
• Denmark = Low growth– Stage 4 since the 1970s

•Most countries = stage 2 or stage 3 of the Demographic Transition•Stages 2 and 3 are characterized by significant population growth•No country is in stage 1 of the demographic transition
Thus, It is easier to cause a drop in the CDR than in the CBR

Overpopulation: A place does not have the carrying capacity(available resources) for its’
populationPhysiological density: # of people per unit area of arable land
Agricultural density: ratio of the number of farmers to the amount of arable land.

Why Might Overpopulation be a Concern?
• Malthus on overpopulation– An Essay on the Principle of Population (1798): Population
grows geometrically while food supply grows arithmetically– Criticism of Malthus includes the following:
• Fixed resources rather than expanding (possiblism?)• Esther Boserup, Julian Simon & Simon Kuznets argue:• More brains = more ideas• More ppl = > demand for goods = more jobs• Friedrich Engels: enough food to eliminate world hunger• Workers don’t control distribution nor get paid sufficient
wages to purchase it

Government programs in India to curb the fertility rate
• -Sterilization Programs- unpopular due to Gandhi’s program
• -Sex-selection tests: outlawed but still in existence• -Outlawing the Bride Price/Dowry which made it
a burden on a family to have a girl• -Population Growth posters to encourage small
families or to choose girls instead of boys
