Stage 1 - High Stationary
- Pre-industrialised society with nearly similar birth and death rates, meaning there is little population growth
- changes are rapid due to high birth and death rates
- rates are high due to little birth control
- high birth rate because need children to work on land for money
- high birth rate because some people have very strong religious beliefs on big families
- high infant mortality rates therefore parents have more children in hope that they will survive to help support the family but the mothers often die in childbirth
- high death rates because of disease, famine, poor diet and hygiene
- because the natural increase is small, the population remains small
- stage is “high stationary” because the high birth and death rates leave little room for the population to expand or contract
- thus leaving it in stationary position of high factors (high death rate, birth rate and infant mortality rate)
- population growth rate is 0
- life expectancy is low, so population is mainly made up of young people
EXAMPLE: Amazon Tribes

Stage 2 - Early Expanding
- birth rate is high due to no contraception
- economy is based on agriculture so people have lots of children to work on farms
- death rate falls due to improved healthcare & medicine and diet
- improvement in sanitation and water supply
- quality and quanitity of food has increased
- transport and communications have increased - movement of medicines and food supplies
- infant mortality rate has decreased
- population growth rate is very high - high natural increase as less people are dying
- changes in total population are static as the death rate dramatically drops and the birth rate is high but slightly on the decrease
- life expetancy has increased but there are still more young people than old
- this stage is urbanising or early expanding because the country is starting to provide more modern facilities and the population is increasing
EXAMPLE: Bangladesh, Nigeria, Egypt, Kenya

Stage 3 - Late Expanding
- birth rate rapidly decreasing as women have a more equal place in society and better education
- equality for women means they are able to follow a career path rather than feeling obliged to start a family
- use of contraception has increased and more women work instead of having children
- natural increase decreases, so total population change becomes steady
- economy changes to manufacturing rather than agriculture, so fewer children are needed to work on farms
- industrialisation and mechanism means fewer labourers are required and general wealth of country is increasing
- desire for materialistic possessions overtakes desire for big family as wealth increases
- death rate falls due to more medical advances
- lower infant mortality rate means there's less need to have a bigger family
- population growth rate is high but not as high as before
- population structure - more people are living to be older, life expetancy has increased
- towards the end of stage 3 the death rate slowly begins to increase as the birth rate falls below it and the population consists mainly of the elderly this when a country enters tage 4 and 5. Stage 3 the country becomes more mature and stable than before, with modern technology and industrialisation EXAMPLE: Brazil, India

Stage 4 - Low Stationary
- birth rate and death rates are low, fluctuating with baby booms and epidemics of illnesses and disease - resulting in a very steady population
- people's wealth improves and they want more possessions meaning less money is available for having children
- population growth rate is 0
- infant mortality is very low
- country has settles into the post industrialisation stage
- more time is spent improving the country rather than building it up
- natural increase is very low which can be good when thhe populaiton in the country is high
- life exptancy is high so even more pepole are living to be older
- towards the end of stage 4, it becomes a natural decrease as hardly any couples are having children and the popualtion begins to age
- birth and death rates are about the same so the population total stays the same
- if death rate goes below the birth rate, and there is no net migration, the total population can begin to fall
EXAMPLE: UK, USA, France

Stage 5 - Decline
- birth rate is slowly falling so there's less money available to raise children because poeple have dependant elderly relatives
- death rate is low and fluctuating
- population growth is negative
- there are more older people than young people
- total population will eventually begin to decrease quite statically because the birth rate will continue to lessen further below the death rate increasing the natural decrease
- fewer couples want to have children and instead focus on their careers and many couples are incapable of having children of their own
- is the pattern of countries all landing into stage 5 remains keeps going, the total population of countries could rapidly decrease
- not originally thought of as part of the DTM but some countries are reaching the stage where total population is declinig where birth rates have dropped below death rates
EXAMPLE: Italy, Japan, Germany
Germany has had to take in foregin workers to fill the jobs. Uk's populaion is expected to reach this stage at 2021
