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.
To be able to describe and explain global and regional trends in family size (household size), sex ratios and aging populations.
Nothing specific needed for this lesson.
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 ratio, and an aging population at the global and regional scales. Answer the following questions using the articles in the 'Useful Resources' box.
Give one statement about the global trends in Family size/household size. Illustrate your points with data.
Give two statements about the regional trends in family size/household size. Illustrate your points with data.
We have sorted data before using the World Development data to recognise patterns. We will be doing the same thing for sex ratio. 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
Give one statement about the global trends in sex ratio. Illustrate your points with data.
Give two statements about the regional trends in sex ratio. Illustrate your points with data.
Give one statement about the global trends for the aging population. Illustrate your points with data.
Give two statements about the regional trends for the aging population. Illustrate your points with data.
