Title: Population and Urbanization Chapter 13
1Population and UrbanizationChapter 13
2Population
- Sociologist study population to consider the
rates at which people are born, die and move in
and out of countries - They examine social factors that influence the
population rate changes
3India
- Second largest population in the world1.03
billion - 17 of the worlds population on only 2.4 of the
worlds land mass - About 1/3 the size of the U.S.
- First in the world to adopt family planning
programs in 1950s - 1/3 (343 million) of the people are hungry
4India
- Indias population is 1.08 billion, Chinas
population is 1.31 billion - USA is the third largest population at 295.7
million people - Indias population will double in 43.8 years
- USA is only 4.6 of total world population
emitting 24 of the carbon monoxidegreenhouse
gases
5Population
- Demography-sociologist that focus on the study of
human populations especially size and rate of
growth - Birth Rateannual number of births per every
1,000 people in an area - 2004India at 22.94 USA at 14.01
- Age-specific birth ratesrate for a specific
group like women 15-54 - India76.5 USA is 42.2 per 1,000
6Population
- Total fertility rate-average number of children
that women in a specific population will bear in
a lifetime - Indiaaverage women bears 2.91 children
- United States2.07 children
- Consider that a woman has the potential to bear
20-25 children in her lifetime - Sociologist want to know what factors make the
child bearing different in different populations
7Population
- Crude death ratesannual number of deaths per
every 1,000 people in a given population - Rate is 8.49 for both India and 8.44 for the
United States - Infant mortality ratedeath rate among children
one year old or younger - United States rate is 7 and India 60 per 1,000
8Population
- Population pyramidseries of horizontal bar
graphs representing a different five year cohort
(people who share a common characteristic like
agethose born in a 5 year period) - Pyramids let us view relative sizes of the age
cohorts of men and women in comparison to each
other
9Population
- Expansive pyramidstriangular, broadest at base
and gets smaller as it goes upincreasing
population with mostly young - Constrictivenarrower at base than in the
middlemore middle-aged and older - Stationaryall cohorts are relatively the same
size, found in wealthy countries
10Population
- India and China account for 32.7 of the people
born between 1990-2000 - 52 of the Indian population consist of men and
women of childbearing ages - India and U.S. have death rate of 8.5/1000
- 12.4 of U.S. population is over 65, only 4.8 in
India - Survival rates are not equal in these two
countries
11Population
- Migrationmovement of people from one residence
to another - Migration ratedifference between the number
entering and leaving an area - Push factorsconditions causing people to leave
(discrimination, unemployment, natural disasters) - Pull factorsconditions encouraging people to
come to an area (jobs, climate, tolerance)
12Population
- Emigrationdeparture from a country
- Immigrationentrance of individuals to a new
country - Three major international migration
- European exodus to colonize the world
- Asians to East Africa, U.S. and Brazil
- Force movement to 11 million Africans to slavery
13Population
- Internal migrationmovement of people within a
country - U.S. has high rates of thiseach year 43.4
million move - In-migrationmovement into an area
- Out-migrationmovement out of an area
- Much of migration is rural-urban and much of it
is movement a short distance
14Population
- Populations constantly change due to births,
deaths, and migrations - Natural increasenumber of births minus deaths in
a year - Rate of natural increasenatural increase divided
by the size of a population at the beginning of a
year - Doubling timenumber of years needed to double
the population size
15Demographic Transition
- A theory stating that a countrys birth and death
rates are linked to its level of industrial and
economic development - This model presented here offers general
characteristics - It has three stages
16Demographic Transition
- Stage One
- High birth and death rates
- Mortality crisesfrequent fluctuations in death
rate due to war, famine, and epidemics (called
positive checks by Malthus) - Life is short and brutallife expectancy is 20 to
35 with women, and children under 5 most
vulnerable - Living in the time of the Black Plague
- Women have an average of 7 live births to ensure
that two of them will live to adulthood
17Demographic Transition
- Stage two
- Transition stagedeath rate declines due to 1.
increases in food supply - 2. Public health and sanitation increaseuse of
cotton clothing and new ways to prepare food - Change is not due to medical technology advances
- Demographic gapdeath rates decline and birth
rates stay highpopulation increases - Urbanizationincreases in the number of cities
- Around 1880 fertility declines as less of need
for many children and the children have a greater
chance of surviving to adulthood and the change
in status of women -
18Demographic Transition
- Stage 3
- After 1930, birth and death rates decline and
population growth slowed - Life expectancy at birth increases to 70
- Reduced infant, childhood and maternal mortality
- Now accidents, suicide, and homicides become the
leading cause of death among young people - For the first time in history people 50 and older
account for 70 of the annual deaths - Japan, and all the countries of North America and
Western Europe are in this category
19Industrialization
- Definitions of countries industrial situation is
difficult - Developed/developingwill be called
Labor-intensive counties - First World/Third Worldwill be called Core
economies - Each of these groups would have different
doubling time, infant mortality, total fertility,
per capita income, percentage of the population
engaged in farming and annual energy consumption
20Demographic Transition in India
- India was for a long time a colony of the British
who came there for raw materials, labor and a
market for goods - Multinational corporations serve much the same
function as the East India Company did in the
past - Demographic transition is different in India
21Demographic Transition in India
- Factors causing declines in total fertility
- 1. less than 50 of labor force works in
agriculture - 2. at least 50 of 5-19 year olds are in school
- 3. Life expectancy is at least 60
- 4. Infant mortality rate is less than 65/1000
- 5. 80 of females 15-91 are not married
- India has met the school and infant mortality
condition - 1.70 are employed in agriculture
- 2. 60 of women, 81 men are in school
- 3. life expectancy is 55
- 4.infant mortality 51.4/1000
- 5. almost all women are married by 19
22Demographic Transition in India
- The birth rates vary throughout the country
- 1975-77Prime Minister Indira Gandhi
- Promoted sterilizations and vasectomies
- And offered incentives to people
- This shows that increasing female education and
status lower birth and fertility rates - India has used family planning to reduce birth
and fertility rates
23Demographic Transition in India
- In India the death rate started to drop in 1920
- Medical advancements, agricultural practices and
mass inoculations - Demographic trap
- Population growth overwhelms the environments
carrying capacity - The concern that the population growth is so
large that people are left without food
24Demographic Transition in India
- United Nations Food Programme (WFP)
- States it is not the lack of food but the lack of
access to food that makes people hungry - The Green Revolution was to use chemicals to make
fertilizer to increase yields - Short term gains but for wealthy farmers
- Displaced the poor farmers
- Use insecticides to kill insects then people cut
down the trees causing floods for people in
Bangladesh
25Demographic Transition in India
- Externality costscosts not figured into the
price of a product but they a price that is paid
non the less - In Bangladesh the removal of the trees allowed
for short term financial gain - When the monsoon rains came terrible floods
killed people - In 199831 million were homeless and 918 dead
- Costs also include clean-ups of the environment
26Demographic Transition in India
- Urbanization encompasses
- 1. process where populations become
concentrated in urban areas - 2. changes in land use, social interaction,
economic activity and landscape - Indian villages contain fewer than 5,000 people
-
-
-
27Demographic Transition in India
- Mega Cities
- Cities that have 10 million people
- There 19 of these in the world
- New York and Los Angeles
- Bombay, Calcutta and Delhi
- 8 (492m) of the world live in this type of city
- Urban Agglomerations
- 20 of population live in 413 of these cities
- A central city and neighboring cities together
- Approximately, 1/3 of the worlds population
lives in an urban agglomeration
28Demographic Transition in India
- Rate of urbanization in labor intensive countries
is due to - In Europe the population growth was able to
emigrate to North or South America or other
places - In India the migrants to the city are coming to
the city as they are forced off the land due to
poor economic and environmental problems - Come to the city with no where to live and few
jobs - No alternatives leads to disasters like the
squatters around the plant in Bhopal - 2,500 people were immediately killed due to a
chemical leak
29Urban Vs Non-urban In U.S.
- Metropolitan Statistical Areas (MSAs)
- Include one or more cities with at least 50,000
people surrounded by densely populated
counties261 in U.S. - Central City--Largest city in MSA
- Suburb--An urban area outside the political
bounds of the city - Non-metropolitan-- geographical areas beyond the
political bounds of the city
30Urban Vs Non-urban In U.S.
- U. S. Conference of Mayors wants community
leaders and public to view cities and suburbs as
socially and economically interdependent - Largest 7 metropolitan areas in U.S. are among
the worlds 30 largest economies - Metro-New York is just behind South Korea in
economy size and ranks higher than Australia, the
Netherlands, Taiwan and Russia
31Urban Vs Non-urban In U.S.
- Regions classified as nonmetropolitan are equally
as diverse as urban areas - Many view rural regions as insular, low crime
rates, strong social connections, little
employment opportunities, distrust of outsiders,
high poverty, low literacy and few services - Some rural areas revolve around a single factory
or university - The most noticeable housing characteristic here
is the 16.6 (1 in 6) mobile homes
