Task 1: The bar chart shows the rate of overweight males and females in Australia from 1980 to 2010.
The given bar chart compares the proportion of overweight Australians, classified according to gender, over the 30-year course from 1980 to 2010.
The initial impression from the chart is that the Australian overweight rates generally increased. Over the last 10 years of the given period, the figures underwent a mild drop for men, and a plateau for women.
In 1980, around 49% Australian men were reported overweight. Over the next 10 years, this figure experienced a marginal rise to roughly 54%, followed by a much steeper growth to a peak of 70% in 2000. The figure thereafter decreased slightly and eventually reached 68% in 2010.
A similar pattern could be observed in the figure for women. In 1980, the female overweight rates stood at 30%. The 1990-2000 period recorded a steady increase in the proportion of overweight females, with its figure rising by 10% every 10 years, reaching 50% in 2010, and eventually it levelled off at this point towards the end of the period.
