8World Population Growth
- 0 CE- lt 300 million
- 1650- 500 million
- 1850- 1 billion
- 1930- 2 billion
- 1960- 3 billion
- 1976- 4 billion
- 1987- 5 billion
- 1999- 6 billion
- Today 6.6 Billion
- Why?
- Plagues, epidemics, undependable food supplies,
poor sanitation, inadequate medical treatment,
warfare led to high IMR, MMR and low ALE - Improvements in the above (especially food
supplies and medical care) led to dramatic
population increases - Impacting events
- Neolithic revolution
- European exploration
- Industrial revolution
- Urbanization
9The J curve
10General Population Patterns Today
- Largest concentrations
- East Asia
- South Asia
- Western Europe
- Eastern North America
- Similarities
- Areas of low elevation and moderate climate,
close to water - High Birth rates- associated with agricultural
countries, low economic development (children are
economic benefit), little urbanization,
contraceptives unacceptable due to expense or
tradition, high levels of illiteracy - Low birth rates- industrial, urban societies,
high levels of literacy, family planning
(children are an economic cost) - High Death rates- same areas as High Birth rates,
but also areas with elderly population

16Theories
- Thomas Malthus English clergyman (1798- Essays
on the Principle of Population) - Population grows geometrically (exponentially) -
2, 4, 8, 16, 32, etc.) - Food supplies (resources) grow arithmetically (1,
2, 3, 4, 5, etc.) - Result being mass starvation unless population is
brought back in balance - Malthusian checks on population wars, famines,
epidemics- want to avoid them? Must limit
population voluntarily - So dont help the poor- it will only make more
of them - Today- ideas held by Neo-Malthusians
17More Theories
- Karl Marx- German social philosopher (1818-1883)
- Poverty results from capitalistic inequalities
(unequal distribution of resources), so, adopt
socialism - Population growth greater production of
economic commodities, thus better life for all, - Did not pan out where applied (Soviet Union And
China) - Esther Boserup- agricultural economist (1965)
- Population growth stimulates greater intensity in
effort and therefore greater amount of food - Is therefore the stimulant of agricultural
development (not the result) - Cornucopian theory-
- disdains the notion that there are natural limits
to growth - Believes planet can hold an endless number of
human beings and provide a limitless abundance of
natural resources. (even petroleum) - sometimes called Anti-Malthusians
18Policies
- Pro-natalist
- Formal
- Government encourages more births through various
incentives - Informal
- Society/ culture encourages more births through
values - Anti-natalist
- Formal
- Government discourages births through incentives
or punishments - Informal
- Society discourages births through encouraging
later marriages, etc.

25Historical migrations
- Out of Africa
- Jewish Diaspora
- Rise and Fall of Empires
- Waves across Europe
- Mongolian Conquests
- Spread of Islam
- European exploration and colonization
- Trans-Atlantic Slave Trade
- Industrial Revolution migrations
- Rural- Urban migrations- currently the worlds
largest migration stream - Developing countries- developed countries
26Questions for discussion
- Do agricultural groups always dominate nomadic?
- Is settling the natural course of development?
- There are numerous cases of nomadic societies
conquering agricultural ones the Hittites
conquest of the ancient Middle East, the
successive movements of Germanic people across
Europe, the Aryan migration into India, the
Seljuk Turks conquest of much of the Muslim world
that began in the 11th century, and the vast
Mongolian conquests of the 13th and 14th
centuries. http//en.wikipedia.org/wiki/Guns,_Ger
ms_and_Steel - Why do some groups seem to be more mobile than
others? - How has transportation technology changed the
migration experience? - How has/ is globalization affecting migration?
27Other issues affecting Migration
- Push and Pull factors
- Place Utility
- A particular areas value, how the lifestyle
there is viewed. - Intervening Opportunities
- Closer opportunities appear more attractive than
further away - Distance Decay
- The further away something is, the less likely
you are to have interaction with it
28Laws of Migration by E.G. Ravenstein (1880s)
- Most migrants travel only a short distance.
- Migrants traveling long distances usually settle
in urban areas. - Most migration occurs in steps.
- Most migration is rural to urban.
- Each migration flow produces a movement in the
opposite direction ("counterflow"). - Most migrants are adults.
- Most international migrants are young males,
while more internal migrants are female.

30- The New Colossus by Emma Lazarus
- Keep, ancient lands, your storied pomp!"
cries sheWith silent lips. Give me your tired,
your poor,Your huddled masses yearning to
breathe free,The wretched refuse of your teeming
shore.Send these, the homeless, tempest-tost to
me,I lift my lamp beside the golden door!
31The U.S. and immigration
- First migrants Native Americans
- New evidence points to multiple migrations- only
one over the Bering Strait Land Bridge - Then various exploring groups
- Irish, Vikings, Phoenicians/ Carthaginians?
Greeks and Romans? - Lies My Teacher Told Me James Loewen
- European explorers during the Renaissance
- English, Dutch, German follow
- Transatlantic slave trade
- Largest forced migration in history
- Various waves of immigration follow Northern
Europe, the Irish, Southern and Eastern Europe,
China, now Latin America - Each new group faced resentment from the already
established ones - NINA myth?
- Concerns over union membership, job stealing,
rising crime, etc.
32- Remember, remember always, that all of us... are
descended from immigrants and revolutionists.
-Franklin D. Roosevelt

35- WHERE YOUR TAXES GO - ILLEGAL ALIENS Attributed
to the LA Times, June 2002 Actually not. - 40 of all workers in L.A. County (pop. 10
million) are working for cash and not paying
taxes. This was because they are predominantly
illegal immigrants, working without a green card.
- Cash workers (including waiters) pay less in
income tax, but they certainly are paying sales
tax, property taxes, etc. - 95 of warrants for murder in Los Angeles are for
illegal aliens. - 95 of OUTSTANDING homicide warrants are for
illegal, not the total - Over 2/3's of all births in Los Angeles County
are to illegal alien Mexicans on Medi-Cal whose
births were paid for by taxpayers. - 62.7 of births list Hispanic as ethnicity- so
all Hispanics illegal? - Nearly 25 of all inmates in California detention
centers are Mexican nationals here illegally. - Actually, statistics say that 23 are deportable
(including any foreign nationals, not just
Mexicans) - Less than 2 of illegal aliens are picking our
crops but 29 are on welfare. See...
http//www.cis.org/ - Illegal aliens not eligible for welfare
36Refugees
- UNHCR

persecuted for reasons of race, religion,
nationality, membership of a particular social
group, or political opinion. - Characteristics of Refugees
- Most move without any more tangible property than
they can carry or transport with them. - Most take their first step on foot, by bicycle,
wagon or open boat. - Generally, they move without the official
documents that accompany channeled migrations. - H.J. DeBlij Human Geography Culture Society and
Space - Can be either
- International or Intranational
- Permanent or temporary
