• stage 1 - high fluctuating
• Economy not developed
• birth and death rate high
• famine and dieses cause this
• fluctuation - pop up and down
• stage 2 - early expanding
• Economy starts to develop
• birth rate still high
• death rate is declining because of better medical supplies food and water

Factors that influence population

• Fat William Eats Hot Plum Tarts
• 1. Food
• When a country develops food supply improves
• people eat healthy and then they live longer which means populations grows.
• The population in Ireland declined during the Great Famine 1845 - 1849
• The poor people had no food when the potatoes crop failed and the good food was exported and Death rate was high
• In Brazil the population has trebled in recent times as there is plenty of food
• 2. War
• reduces population
• soldiers and civilians get killed
• death rate is high
• women and men get separated for long periods of time so birth drops
• Ireland lost thousands of soldiers during world war 1 and 2
