3Studying Population
- Population Geography
- The study of SPATIAL variations in the
distribution, composition, migration, and growth
of populations over time. - Demography
- The study of human population dynamics. It looks
at how populations change over time due to
births, deaths, migration and ageing. - Demographics
- A term for population characteristics.
Demographics include birth rate, death rate,
immigration, age, income, sex, education,
occupation, religion, nationality,

6Studying Population
- Factors that may lead to population increase
include - Food
- Health
- Economic Growth
- Migration
7Studying Population
- Growth Rate
- the number of persons added to (or subtracted
from) a population due to natural increase and
net migration. - Birth rate number of live births per 1,000
population per year. - Death rate number of deaths per 1,000 population
per year. - Rate of Natural Increase
- birth rate death rate rate of natural increase
8Studying Population
- Factors that contribute to the decline in death
rate include - Better Nutrition
- Better Access to Medical Care
- Improved Sanitation
- Better Immunization
- Net Migration immigrants emigrants
9Studying Population
- Effects of Population Increase
- Increased poverty
- Resource depletion
- Medicine shortages
- Urban sprawl
10Studying Population
- A specific pattern of population growth has
occurred in many developed nations during the
past 60 years.

11Studying Population
- Factors that may lead to population decline
- Heavy Emigration
- Disease
- Famine
- War
- Sub-replacement Fertility
- a fertility rate that is not high enough to
replace an areas population. Sub-replacement
fertility rate is 2.1 children per woman or
higher.
12Studying Population
- Population Decline in the past
- The Black Death
- Old World Diseases
- Potato Famine
- Population Decline today
- Sub-replacement Fertility Levels
- Migration (to be discussed in the next lesson)
13Studying Population
- Why low sub-replacement fertility rate?
- Urbanization
- Contraception
- Government Policies
- Exception United States where natural increase
rates have remained stable - And within the US, incredible regional variations

17Studying Population
- Effects of Population Decline
- Deflation
- Rise in the standard of living
- Population aging
- Small impact on the environment
- Political power?
18In the developed countries, there are fewer and
fewer young people and more and more elderly.

21Population Pyramids
- A population pyramid is two back-to-back bar
graphs, one showing the number of males and one
showing females in a particular population in
five-year age groups (also called cohorts). - A great deal of information about the population
broken down by age and sex can be read from a
population pyramid, and this can shed light on
the extent of its development. - Birth rate trends
- Death rate trends
- Number of economic dependents (lt15, gt65)
22Population Pyramids
- Three basic shapes of population pyramids.

30Global Village
- If the world were a village of 1000 people, it
would include - 584 Asians
- 124 Africans
- 95 Eastern and Western Europeans
- 84 Latin Americans
- 55 former Soviets
- 52 North Americans
- 6 Australians and New Zealanders
31Global Village
- The people of the village would speak
- 165 Mandarin
- 86 English
- 83 Hindu/Urdi
- 64 Spanish
- 58 Russian
- 37 Arabic
- and the remaining villagers would speak a variety
of 200 other languages
32Global Village
- The religion practiced by the villagers would be
- 329 Christians (among them 187 Catholics, 84
Protestants, and 31 Orthodox) - 178 Muslims
- 167 "Non religious"
- 60 Buddhists
- 45 Atheists
- 32 Hindus
- 3 Jews
- and 86 of other religions
33Global Village
- Financially speaking in this 1000 person
community - 200 people receive 75 percent of the income
- Another 200 receive only 2 percent of the income.
- Only 70 people of the 1000 own an automobile
(although some of the 70 own more than one car). - About one-third have access to clean, safe
drinking water.
34Global Village
- Looking at the social structure of the village,
there are - 5 soldiers
- 7 teachers
- 1 doctor
- 3 refugees driven from home by war or drought
- and half of the adults are illiterate
35Global Village
- The village has a total yearly budget, public and
private, of over 3 million - 3,000 per person
if it is distributed evenly. - Of the total 3 000 000
- 181,000 goes to weapons and warfare
- 159,000 to education
- 132,000 to health care
36Global Village
- Nuclear Power in the Village
- The village has buried beneath it enough
explosive power in nuclear weapons to blow itself
to smithereens many times over. These weapons are
under the control of just 100 of the people. - The other 900 are watching them with deep
anxiety, wondering whether they can learn to get
along together and if they do, whether they
might set off the weapons anyway through
inattention or technical bungling and if they
ever decide to dismantle the weapons, where in
the world village will they dispose of the
radioactive materials of which the weapons are
made?
