ch.2 population and health Flashcards
four major population clusters
- south east asia
- South Asia
- east asia
- europe
- North America can be called 5th
- core because of resources
where do more people live than in the rest of the world
east asia, Southeast Asia, South Asia, and europe
India
-does not have money to import food
carogram
- map that shows size of country by population, not by land area
- distorts size of country to show population
most populated coountry
china
russia
largest by land area, but on cartogram map, russia is much smaller than china
japan
contains almost as many people as russia
east asia
- main populated countries are japan, china, and korea
- china in about 1.8 billion people
- popular because of cities and export based area
South Asia
- india 1.6 billion
- almost have all of worlds population in china and india
- other high population countries in South Asia are Sri Lanka, pakistan, and bangladesh
europe
- a more evenly distributed population
- has higher concentration of people living in urban city life
urban vs. rural
europe is urban city life population
- south, east, south east asia mostly rural and farmers
south east asia
- indonesia
- Indonesia contains 13, 677 islands, which all makes up the one Indonesia country
- issues are lack of resources, have capital city, but the biggest problem is communication
North America
could call it the 5th somewhat population clustered region
4 areas where people generally don’t live
- wetland
- dry land
- high lands
- cold land
ecuneme
permament human settlement
- doesnt include people who come and go or conduct research
- no ecuneme in antarctica
dry land
- can’t sustain life
- people don’t avoid hot areas because you can get water there, unlike dry land ( florida is hot, but there is still water)
- difference between hot and dry land is resource of water
- examples of dry land are deserts and egypt
- in egypt, the concentration is extremely high along the nile, no one lives anywhere else in egypt
- much of earths oil comes from dry land like Saudi Arabia
wetland
- too much water, humans can’t survive living in water
- difficult to sustain life
- ## cant grow things on water
cold land
- antarctica, cant sustain life
- too cold is biggest problem
high lands
- not enough oxygen to sustain life
- as you get higher, oxygen level decreases
- exception- people live in Central America, capital city of mexico, one of most densely populated areas in South America is the one exception for living in high lands
3 types of population density
arithemtic
physocoligcal
agricultural
- aproaches to describing distribuion of people
arithmetic density
- total population/ total land area
- not going to tell much except how many people live there
- answers the “where” question (where most people live)
- egypt- arithmetic density is 80 people per sq mile, not a lot
- japan on the otherhand in 1,000 per sq mile
- egypt has overpopulation problem even if statistics show it, the statistics can be misleading
- can be used to compare conditions in different countries because the total population and total land area are easy to obtain
physocological
- number of people supported by arable land
- total population/ arable land
- egypt- 2,296 people/ arable land, overpopulated because not enough resources for the amount of people
- if physcological density is high, most likely overpopulated
- provides insight into relationship between size od population and available resources in region
- compares population to resources
arable land
land that can be farmed
agricultural density
- ratio of number of farmers to arable land
- number gives us indicator if its a more developed or less developed country
- the two types of agriculture are commerical and substance agriculture
- high agricultural density is a ldc because need more farmers to farm the land
- low agric. density is mdc because they can run more efficiently with less farmers because of technology
- because of technology, plants grow faster in mdc than in ldc
- technology is the game changer, no tech, by hand, which is substance farming and takes more people and longer.
- measures economic efficiency of food production
substance agriculture
- farmers grow the food themselves and their family eat, and thats it, grow for yourself
- growing by hand
commercial agriculture
-farmer grows food, sells it
census
statistical count of population
-happens every decade and on the years that end in 0
two reasons that a census is controversial
nonparticaption
- homeless people, enthnic minorities, citizens without proper immigration papers less likely to complete census form
sampling
- statistic sampling can be helpful for more accurate count and identifying characteristics of people, housing and businesses
most populous cluster
east asia
- 1/4 of world
how do geographers unerstand relationships between populations and resources in country
- examine countrys physocoligcal nad agricultural densities together.
- ex. phy. density of both egypt and netherlands are high, but dutch had much lower agric. density than egyptians
- geos concllude that both dutch and egyptians but heavy pressure on land to produce food, but more efficient dutch system requires fewer farmers than egyptians system
CBR
- number of births per 1,000 people already alive in society
- if answer is %, not CBR unless it could be in percent form out of 1,000 like 120 could be 12%
- higher in ldc than in mdc
Why is CBR higher in ldc than in mdc
- don’t have access to birth control might be able to just taboos against them
- don’t have education – more education available to females less children they have
- Imr- infant mortality rate higher so they have more children. Woman could have eight children the only three may survive
- children can work help with substitutes farming in LDCs
CDR
- number of deaths per 1000 people in population
- higher in MDC because we have an older population
- revolves around aging population
NIR
- percentage of growth annually
- Global NIR percentage is 1.2% which means 84 million people per year added
- much of growth in less developed countries
- LDC keeps growing even if they don’t have the resources to provide
Doubling time
- amount of time it takes for a population to double
- The higher the NIR the time goes down vice versa
TFR
- number of births a woman will have in their childbearing years 15 to 49
- LDC have children earlier because they don’t live as long and might take two or three pregnancies to have a child that will actually survive
- MDC – don’t have children till later
- this is not a lifetime number
- hire in LDC also because of their lack of healthcare
IMR
- 0 to 1 number of babies born alive but die before age of one
- higher in LDC lower in MDC
Life expectancy
- Live longer in LDC shorter in MDC
Dependency ratio
- below 15 above 65
- people that cannot work or provide for themselves
- when in years that you can work you pay money in your check to go to your social security
- when older than 65 you get social security check every month
- older people stress government out because you have to care for them
- we are paying for the older people
- Younger than 15 stress government out because government provides a school for them
Sex ratio
- males per 100 females
- more females globally
- fortunes of China have policy that allows one child per family
- more guys in China
What do you MDC and LDC population pier mid look like
MDC are almost all the same or a little less older people
- LDC more children so looks like a pyramid
Naples Florida
Old people
Lawrence Kansas
More people in their 20s because University of Kansas so more college kids
Un Alaska Alaska
Lots of males middle age because middle military there
-if area is more mail and middle-age answer will mostly be a military base
Texas
Close to the Tex-Mex border so more younger children
Migration
-population change
Natural
Countries growth rate does not include immigration
