Population, Globalisation, and development Flashcards
What is estimated to happen to the worlds population?
It is to peak then start to decline due to slowing birth rates
What is spacial perspective
the where of population size density and change
What is crude density
total number of people divided by land area
what is nutritional density
ratio between total population and the amount of land under cultivation in an area
Why does population density matter
use of resources and space use in urban areas
What factors affect population density and distribution
accessability to land, access to water, topography, land quality, soil fertility, climate and weather, and natural resources, as well as history eg of industry
What can population distribution and density factors be used to predict
the future of population
What is a flaw with an ageing population
lots of people depending on social and health services often provided by small economically active section
What is a population pyramid
representation of a population based on composition of age and gender, shape can determine a ageing/growing population and show trends
what does a triangular pyramid depict
a youthful pop with high birth and death rates
what does a ‘beehive’ pyramid depit
an ageing population with a long life expectancy
Formula to calculate population growth
births-death+(immigration-emigration)
what is the crude birth rate
no. of births in a year per 1000 persons of a pop, does not break it into categories eg ethnicity
what is the total fertility rate
the number of births a women between 15-49 would be expected to have
less than 2= declining
more than 2= growing
What is the crude death rate
no. of deaths in a year per 1000 persons of a population
does not account for categories in society eg age
what are factors affecting death rates
gender, poverty, inequality, healthcare access, diet, employment, environment pollution
what is infant mortality rate
no. of infant deaths under 1 in a year per 1000 live births
demographic transition model- stage 1
high birth and death rates, no pop increase, traditional triangle shape
demographic transition model- stage 2
mortality falls, birth rate stays high, population increase
demographic transition model- stage 3
mortality is low and birth rates begin to fall- most common in developed countires
demographic transition model- stage 4
mortality and birth rates low, box shaped pyramid
demographic transition model- stage 5
very low birth and death rates with little pop growth
What is the definition of migration
residential relocation of a group family or person from on place to another
What is net migration
gain-loss of immigrants
