The proportion of premature births by mother’s age and the frequency of births in England and Wales in 2011 are depicted in the given bar chart.
Overall, it can be seen that the rate of the former type of births varied as the age varied, but the latter’s rate advanced as the age advanced.
As per the chart, the rate of single births before 37 weeks of pregnancy was seen higher than the rate of multiple premature births in all the age groups. The highest incidents of the former type of births were reported among the youngest age group(7%) and the latter type was among the oldest (just over 3%) .
The percentage of premature single births is seen declining to just over 5 as the age advanced to 34. However, the opposite was seen between these ages in case of premature multiple births (from 1 to 2).
In case of the both types of premature births, among the two older age groups, the rate was seen comparatively higher with a gross of around 8 and 10% respectively.
