Unit 2 Flashcards
Climate
early population centers formed in the midlatitudes ( the middle of the poles and the tropics)
landforms
where there was good land for farming there were larger population centers
water bodies
populations grew near water so they had better access to water and made crops grow faster
culture
urban centers are also centers of culture
economics
urban centers are the hub of economic activity, there is a higher influence of the city so it is more pwerful
history
the earliest population centers tend to still be the largest now
politics
urban centers tend to benefit most from the government, being provided parks schools, etc.
ecumene
ancient Greek term known as the inhabitable, or habitable earth
arithmetic
total population/ total land area
physiological
total population/ total farmable/arable land
agricultural
population of farmers/ total arable land
carrying capacity
the number of people that an area can hold, the maximum population density of a place
rapid expansion
the base is larger with many children, but as they mature fewer people live because of the high death rates
late expansion
beehive/bell, base is wide and stays that way until going to old age were there is high death rate, mostly NIC
slow growth
box shape, the population is stable, mostly developed countries
zero and negative growth
convex, base is small, then wide in the middle, high developed countries
fertility
the fertility rate will be higher in less developed countries then higher developed countres
mortality rate
the higher the mortality rate the less developed and more rapid growth there is
migration: demographic equation
migration can cause the demographic model to be convex because of the amount of people in the bearing bracket that migrate to other places.
zero population growth
when there are fewer children being born, people still migrate so there is a bigger bearing bracket
population doubling time
the time that it takes for the population to double
the epidemiological transition
changing patterns of population age distributions, mortality, fertility, life expectancy, and causes of death
exposure and starvation
this is most common in LDCs and cause the population to be very small as people continue to get older
chronic disease or cardiovascular disease
these diseases are mostly in the NICs because people die earlier than MDCs and don’t have the technology to prevent the deaths
geriatric, delayed chronic/CVD, and cancer
these are mainly in MDCs because they are less likely to be prevented and find a cure even in the MDCs
Russias population sink
the population of Russia sank because the deaths were outpassing the amount of children that were being born
population pyramids
a model that shows how the population looks in a city
age structure
the age in a population pyramid is split into 5-year gaps to show all of the ages as accurately as possible
