Population Change Revision

So for all of you awesome level 1 Geography students that were absent period 1 today learning how to accept your prizes, here is what you missed today....

First things first, click HERE to get the revision sheet that we filled in.

There are 2 main methods of showing population change over time that we looked at in class. You should be able to describe and explain both of these and use specific detail to relate them to India.

1. DEMOGRAPHIC TRANSITION MODEL

The first row on the sheet is to do with the Demographic Transition Model, in the first column you needed to draw a basic diagram showing the main characteristics of this model and in the next column, you needed to EXPLAIN (say what and why) the changes this model shows. For example, Stage One: Birth Rate and Death Rate high so little population change. Reason is no healthcare or education, poor sanitation. If you have forgotten all of this stuff, HERE is the link to the blog post about the DTM. Remember to identify where the natural increase is, this is how the population is growing.

If you can't find the notes in your book, here is an idea of what it should look like with some basic reasons for the changes underneath. IMPORTANT NOTE: This diagram says India is in Stage 2, this is incorrect in 2014 India was at the beginning of Stage 3 .



In the last column, you should state some statistics about the population changes in India.

• India is currently at the beginning of Stage 3
• It has moved from Stage 2 to Stage 3 as education on contraceptives and family planning was improved in the 1970s decreasing the birth rate from 41/1000 to 21/1000.
• India's current death rate is 7/1000
• India's population growth rate is 1.58%

2. AGE SEX PYRAMIDS

In the first column of the second row, draw 3 basic diagrams representing India's age sex pyramids in 1950, 2014 and a prediction of what it will look like in 2050. Click HERE to access the web page that will model this for you. On each pyramid, label the characteristics of it. For example, wide base = high birth rate, steep sides = high death rate and short pyramid = low life expectancy. If you have forgotten about all of this, HERE is the link to the blog post about interpreting age sex pyramids.

In the next column, EXPLAIN (say why) the population pyramids have changed from 1950 to 2014 and then use the last population pyramid of 2050 to predict why the population might change during this period. Don't forget to use terms youthful and aging population, young dependents (aged 0-14) , old dependents (aged 65+) and working age (aged 15-64)

The last column is for some specific detail relating to India. You could include, population totals at each stage, % of population currently under the age of 14, their current population growth rate and you could compare their birth rate and death rate in 1950 to their current birth rate and death rate.

Hope this is helpful! For all of you amazing level 1 geographers who were present in class today and who completed this task already, don't forget about the essay question that you could answer as revision at the bottom of the page. I am more than happy to mark this for you so get amongst it! 

Only TWO MORE GEOGRAPHY PERIODS LEFT!!
