001 - Population

Trends

Geographic knowledge and understanding

Global and regional/continental trends in family size, sex ratios, and ageing/greying.

Concepts

Changing global and regional trends in household size, sex ratio, and ageing present a range of possibilities. The change in population structure due to these changes shifts power.

Aims

  • To be able to describe and explain global and regional trends in family size (household size), sex ratios and aging populations.

Key Terminology

Nothing specific needed for this lesson.

Activity One - Describe

As always it is good to look at the data first to recognise a trend in what has been happening. For this syllabus point we specifically need to look at the trends in family size, sex ration, and an ageing population at the global and regional scales. Answer the following questions using the articles in the 'Useful Resources' box.


Household Size - UN Report

    1. Give one statement about the global trends in Family size/household size. Illustrate your points with data.
    2. Give two statements about the regional trends in family size/household size. Illustrate your points with data.


Sex Ratio - World Development Report

We have sorted data before using the World Development data to recognise patterns. We will be doing the same thing for sex ration. Use the following data to create your graphs.


                • Population, female (% of total)
                • Population ages 0-14, female (% of total)
                • Population ages 15-64, female
                • Population ages 65 and above, female (% of total)
                • Time > 2015, 2005, 2000, 1995 to 1965


      1. Give one statement about the global trends in sex ratio. Illustrate your points with data.
      2. Give two statements about the regional trends in sex ratio. Illustrate your points with data.


Ageing Population - Third and Fourth Resources and the Youtube Clip

  1. Give one statement about the global trends for the aging population. Illustrate your points with data.
  2. Give two statements about the regional trends for the aging population. Illustrate your points with data.
