what is fertility rate

how is birth rate calculated
(births/population)x1000
what is death rate

how is birth rate calculated
(deaths/population)x1000
how do you calculate natural increase/decrease
look at demographic transition model
life expectancy is?
age someone is expected to live to
dependancy ratio is?
non economically active / economically active
what does a population pyramid show
distribution of various age groups in a population (country or region)
different population pyramid stges
stage 1: expanding
stage 2: expanding
stage 3: stationary
stage 4: contracting
demographic transition model?
shows relationship between births and death rates. describes how over a period of tome a sequence of change in population takes place
example and stage 1 of DTM
high changes between birth and death rates
eg. few far apart groups
stage 2 and examples of DTM
birth rate high death rate falling rapidly
eg egypt kenya india
stage 3 and example of DTM
birth rate falling rapidly death rate falling slower
eg. brazil
stage 4 and examples of DTM
birth rate falling slower death rate falling very slow
eg. usa uk france japan
stage 5 and examples of DTM
slight fall in birth rate death rate stable
eg germany
3 problems facing country of an ageing population
greater demand in services (pensions health care residential homes)»_space; paid by smaller proportion of people of working age
increasing amount of money for residential homes and sheltered accomodations and health care eg. free bus passes or prescriptions
increasing dependance on economically active to provide consumer goods and services and money through taxation
less money for younger age groups eg. education social amenities and improvements in transport
3 problems facing the eldrely with an ageing population
many have to live alone specially women when husband dies
most can’t afford residential homes (2000euros a month) others can only afford by selling homes or using life savings
long waits for hospital eg. hip replacements
those willing and fit enough to work often face prejudice and bias due to age
urban areas: scared of crime and traffic
rural areas: no transport»_space; can’t get to hospital doctors and shops
