AP Human Geo Unit 2
population /migration
Modern medicne and technolgy caused our population in the 1800s to increase
2.1 distrubuation of resorces
Ex = money ,food water ,edication , health care and all examples of resorces that are not distubtued well.
spatial pattern = clustered and dispursted
clusted = large cities disburst = country or rular area
physical factors
lower lying areas with fertile soil tempture and climate
near ocean or river with easy ocean acess
avoid too dry,wet,cold,high temps
3/4ths of the world live in 5% of the world
Human factors
culture - similar belifs ,acess to have relligons belife
ecnomy - develped or not
history,politcs - courpet politics = move away
Types if density
-arthmic density = population /land use
peoples patterns over land
-phycolgisal density =population/ arable (farmland)
egpt need to trade with others to get densiy
the more people over farm land square feet more people to care for the farm land
Agicultre density = # of farmers / arable land
shows levels of ag productiviy
High=lot of farmers not technolgy
2.2 consequences of population distribution
Reasons and density disrubation matters
ecnomic more/less wealth or resorcues
social fewer schools and hospital in less dense areas rural Ia vs desmoins = more efficent public sevices in high densiy areas
political =more less influnce (national vs state government
Envirmental= can the envirment handle it ?
carring capicty = amount of people envirment can sustain
over population= beyond carrying capicty
Espn
ecnomic
social
political
n = envirmental
2.3 population composition
sex ratio= number of males per females
mdc’s = more females
higher life expectcy for women (type of carrear vs men)
ldc’s culture factors for favoring boys
dwry systme ( pay money for girl to marry boy and the boy family gets that money)
Dependcy ratio = number of people too young or too old to work
large dependcy ratio = greater burden on workers
higher in ldcs but growing in mcds
population pyrimds
percent of men and women in diffrent age brackets that predicts market for goods and services. predicts needs of socity.(ex = more workers or schools)
2.4 population rates
Natural increase weight % of populatation groth/year (mirgration is not included)
Cbr-cdr= nir
conver to percentage
higher in ldcs
Total fertillity rate: averge number of children a single women has in in there life time
better predicter of future cbr
world is 2.4
more than 5 in africa
less than 2 in mdcs
us averge 1.8
pattern= falling in every region today
population in whole declines when below 2.2
2.6 malthusian theroy
popualation grows much faster than food production
need natural checks
contexts = he had jsut seen britan enter stage 2 of dtm
this theroy was made in 1798
potential limitations
dtm stages
industrulazation ad vancements
food vs population
word supply of recorses are not fixed
befits more people
Borscup theroy
more labor= more inovation to produce food
Neo- Matlthusis
earths recorces deplenish today becuse of over population
still cant hit crisis point
will promote polices that control population
2.7 population polices
Antinatilst = government policy to encourge a decrase in birth rates in soctiy through brith control better health care and female empowement
stages 2 and 3
pronatilist
government policy to encourge and increase birth rates ‘
stages 5
2.8 women and demographic change
Goal= lower birth rates
stage 2 and 3 countries (wide pyrimids)
1 controception and family planning
imedate results
cultrue resistent in middle east
2 Better health care
lower child morality= smaller familes
3 Female empowrment (edication, jobs, health
long term sloution
reguires changing social values and roles of women
Ravenstien’s laws of migration
1 migrates typiclly only travel short distances
a Further away= less likely to migrate
2 those those that travel long distance settle in urban areas
3 most migrates occers through step migration
4 Mirgaration creates rural to urban
5 migration creates counter migrats
6 most migrates are young males from 25-45
a what about women
changing roles of felmales impact migration
women migrates
typiclly migrate within a country
internatinal= young males
however, as roles are changinng= more internatinal migrates
2.9 Agining populations
aging is determend by
bith rate
death rate
life expecticy
politocal cansequnces of elderly dependcy ratio
ederly vote increases- ederly issues pushed at officals
focus on finacal and healthcare programs
Government polices = asistance
social secerity
medicare
increase in pro nalist polices
infucles of immigratiin
social consequnces of age population
who will take care of old people
more responsibilites on children
what services would be indended for the elderly how dose taht affect the culture impact
ecnomic conesqunces of aging populations
increase cost of socity- taxes increased pressure on the work force
adult children have pressure to take care of family
workers needed
imigaration
2.10 causes of migration
ecnomic reasons
push = lacl of jobs
pull= jobs avilable
Guest workers popular mostly young men
social/culture reasons
push
religous persicution
discrimnation
lack of schools/ health care
pull
relgious freedoms
laws agaisnt discrimnation
acess to edication/ health care
obsitcal = discrimantion learning a new languge
oppertunites = laws in home country improve
politcal reasons
push
war poltical persicution freedom of speech
pull
safety, freedom 60 millon forced migrate today
Refugee= forced out of country
internally displaced person= still in country
Asylym seeker= migrated to another country waiting in refugee status
obstical= qouta laws, paperworl
oppertunity= granted asylumm in difftent country
Envirmental reasons
push= naturl disastors drought polution
pull= climate, safety, fertille land
Emigrate vs immigration
Emmigration= exit migration
imigration = into an area
Immigration-emmigration= net migration
2.11 forced and volunterry Migration
Forced Migration
permet movemnet usally caused by cultural factors (not always
ex= slave trade,reffuges native americans
volunterry migration
movemnt taken by choice that is ofton perment
transitional = arcoss international borders
only 1 in 10 total migrates
Ldcs to MDCs
Largest flow=
asia to europe north america and persian golf - latin america to north america
- african to america
other types of vlountary migration
transhumance = sesonal movement for livestock
cooler places in the summer, warmer in the winter
nomadic goat hereders
step= move in a serious of steps
-farm villge to town to city
chain= one member of a family moves and other follow
-scandinaviens in midwest
Internal
movement within national borders
Intereginal(out)- one local
one local region to another rural to urban (90%)
Intrareginal (within)
within a reginal (older cities to newer suburbs
Guest workers
us with mexican workers in the 1900s
nw europe affter ww11 turkich to europe
sw asia
2.12 effects of migration
Effects on country if orgin
postives = relif of overcrowding and recorces, Reittance = money sent back from guest workers
Negitves = working age, people leave= incresed dependcy ratio
brain train
Reciving country
diversity/culture contribution = new foods new langues /words divers from entertainment, religous traditiions
ecnomic= more workers = more ecnomic productivity and innovative
conflicts= religous belifs, acess to jobs,culturl pracitoce
strain of services= schools police healthcare
