Today's lesson focused on how populations grow over time and how this might lead to a population's growth being sustainable or unsustainable
Factors causing a population to grow quickly over time can be linked back to the ideas we talked about previously such as high birth rates due to cultural practices, religious beliefs, women's standing in society and high infant mortality rates. A growing population will also need to have a lower or declining death rate caused by increase to healthcare, improvement in sanitation, higher incomes and overall higher standard of living. Click HERE for a little look at what Hans Rosling a Swedish statistician has to say about the link between religious beliefs and a country's birth rate. Fascinating stuff!
A population's growth will be greatest during stages 2 and 3 of the Demographic Transition Model. India is currently in Stage 3 and is experiencing huge population growth due to natural increase (birth rate - death rate = natural increase). Over time, the characteristics of the population will change as the high birth rate decreases leaving a big bulge of young people for the next 50 years before they become a big bulge of older people as life expectancy for country increases.
India has a youthful population. This means it will face one set of problems now due to the high number of people below the age of 14 and will face a different set of problems in 50 years time when they have a high number of people aged above the age of 65.
