Limitations Of The Demographic Transition Model

# data[].attributes.body
The Demographic Transition Model does not account for migration, disease outbreaks, wars. etc.

# data[].attributes.body
The Demographic Transition is based on birth rates, death rates, and the population. In stage 1, which was most of the world before the Industrial Revolution, birth and death rates  were both high so the population rarely grew. In stage 2, medicine improves so now the death rates are lower but the birth rates are still the same so the population grows fast. In stage 3, the death rates are low and the birth rates are gradually decreasing so the population is now increasing less. In stage 5, the birth rates are low, death rates are low so now the population is now stopped growing and will possibly decline.

There is a loss of water, food, and shelter because there are more people and that will use up more space and nutrients. There will also be an increase in crime, since there is less food, water, and shelter to go around and everyone will be fighting for it. There will be habitat loss for the animals since we will be farming it for new areas to live in. More species will become extinct since there is less food to go around.

The industrial revolution also improved the role of women  and from there on, they were allowed to vote, work at different areas only men were able to, and many more. Since medicine and sanitation have been improved, people started to die less and less so there was an increase in population by a lot.

Helping other countries improve their healthcare and living conditions will lead to overpopulation.

Population has started to slow down and fertility rates are declining and that will mean drastic population increases will come to an end.

Ever since the medicine and sanitation has been improved, people started dying less and less.

The industrial revolution in the UK helped make peasants into workers. From then on, manufactured goods were mass produced and widely available. Transportation, communication, and medicine has improved since then.
