Title: Population and Urbanization Chapter 13


1
Population and UrbanizationChapter 13
  • By
  • Dr. John Brenner

2
Population
  • 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

3
India
  • 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

4
India
  • 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

5
Population
  • 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

6
Population
  • 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

7
Population
  • 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

8
Population
  • 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

9
Population
  • 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

10
Population
  • 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

11
Population
  • 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)

12
Population
  • 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

13
Population
  • 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

14
Population
  • 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

15
Demographic 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

16
Demographic 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

17
Demographic 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

18
Demographic 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

19
Industrialization
  • 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

20
Demographic 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

21
Demographic 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

22
Demographic 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

23
Demographic 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

24
Demographic 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

25
Demographic 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

26
Demographic 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

27
Demographic 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

28
Demographic 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

29
Urban 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

30
Urban 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

31
Urban 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
