The table shows changes in the number of women aged 40-44 years who gave birth to children in Australia during the period of 1981 to 2006.
The most striking feature is that women who ever gave birth to two children are the highest number in all sampled periods. Meanwhile, women who gave birth to one child are the lowest number during the periods of time.
Moving into more detailed analysis, the number of women who never gave birth and women who gave birth to one child are below 10 per cent in the year 1981 and 1986 but then both of them had the same patterns to rise above 10 per cent during 20 years (12.8 per cent in 1996 and 15.9 per cent in 2006 for women who never gave birth, while 11.3 per cent in 1996 and 13.2 per cent in 2006 for women who gave birth to one child).
Furthermore, women who gave birth to two children rose constantly over the time frame which started at 29.0 per cent in 1981 and hit the highest number of 38.3 per cent among others in 2006.
However, in contrary, women who gave birth to three children and woman who gave to four or more children had the same patterns slowly dropped from 27.4 per cent to 21.5 per cent and from 27.6 per cent to 11.0 per cent respectively.
