My essay:

The bar chart compares the percentages of Australian men versus women in six different age brackets who did regular physical exercises in 2010.

Overall, except for the youngest group, proportionally more women than men regularly participated in physical activity. In addition, male participation decreased until the age of 44 before rising in the older age groups, whereas the almost reverse was true for females.

For men, the level of participation was highest, nearly 53%, for the youngest age group. It declined to just under 40%, the lowest point in the chart, for those aged between 35 and 44, and then increased to a little below 47% in the oldest age group.

For women, just under 48% of those at the age of 15 and 24 were physically active on a regular basis. This rose by precisely 5.6% to about 53% for the 45-64 year olds, which was slightly higher than the greatest figure for males, a 0.5% differential. The lowest proportion for women occurred in the 65-and-above age bracket, exceeding that of men by 7.6%, 47.1% against 39.5%.
