The pie charts reveal an increase in working time of the working mother as their young children’s ages in Great Britain.

 Firstly, we can see the proportion of working full time mothers increases as their children grow up. According to the first two charts, this proportion remains 11 percents while their children are under 4 years old. However, this percentage increases slightly to 14 percents as their children are from 5 to 9. When their children are older, it rises sharply and account for 29 percents. 

Likewise, the proportion of mothers who work part time also doubles when their children are from three to four than they are under 2 years old and account for 35 percents. This proportion rises considerably to 48 percents as children grow bigger. However, as the children are more than 10 years old, the proportion declines by 3 percents. 

In contrast, the proportion of mothers who do not work decreases as their children grow up. Indeed, this proportion is 70 percents while their children are under 2 years old. However, it reduces to 54 percents when the children are bigger. In a similar pattern, it gets to slightly more than 25 percents as their children are older than 10 years old. 

In summary, we can see an increase in working time of the working mothers as their young children’s ages.
