Figures reveal a 17 per cent increase in the proportion of mothers terminating their pregnancy.
In 2006, 47 per cent of women who were already mothers to at least one child had an abortion, but this rose to 55 per cent last year.
Executive Director of Right to Life, Peter Williams, told Premier News Hour the figures are very concerning.
He said: "This is a very sad situation, it's a tragic situation, it's a horrific situation, but it's one that's enabled by a culture that enables abortion on demand. That needs to change."
Williams claimed that the British culture normalises abortions and that could be a factor to the increase.
More than two-thirds of women having abortions in 2016 were either in a relationship or married, up from half a decade ago.
Williams explained it was going to take a change in the heart of people to reverse the trend but also a change in the law.
He said: "We're going to need to change by virtue a humanised political debate over exactly what we want to see in our country, that means changing the law, it is also changing the culture so people view abortion as what it is, destruction of an unborn child."
Overall, the abortion rate has remained stable, at 16 abortions per 1,000 women of reproductive age.
Abortion rates have been decreasing among women under 30, but are rising among those aged 30 and over. The report shows abortion among women aged 35 and over has increased by almost 2,000.
Williams urged Christians to respond with prayer and action by joining pro-life organisations and petitioning to their local MPs.
On the other hand, the British Pregnancy Advisory Service (BPAS), which provides abortions, views the data as a need for more access to good abortion services and want abortion should be removed from criminal law.
Chief Executive Ann Furedi said: "We are a society that trusts women to make their own choices when faced with an unplanned pregnancy or a pregnancy they cannot continue with, and we need an abortion framework which reflects that."
