The number of women from Ireland having abortions in the UK rose to 3,735 in 2014. It is the first rise in 12 years and means that on average, 10 women a day are travelling to the UK for abortions.
But the increase, up from 3,679 in 2013, is still far behind a high of 6,673 in 2001.
Figures from the UK Department of Health show the number and rate of abortions among Irish girls under 20 has also declined from 324 in 2013 to 273 in 2014. Eighteen to 19 year olds make up the majority of women under 20 who are having abortions.
Commenting on the figures, Niall Behan of the Irish Family Planning Association said: "In 2014, over 3,700 women and girls living in Ireland sought an abortion.
"Instead of providing necessary health services, the State turned its back on these women by obliging them to rely on the healthcare system of the UK.
"Since 1980, almost 162,000 women and girls have had to make this journey to the UK, and assume all the financial, practical and emotional burdens involved in travelling abroad for abortion services."
Helen Deely of the HSE Crisis Pregnancy Agency pointed out the number of women travelling from Ireland to services in the Netherlands had fallen. It was 461 in 2006 (the first year of data collection) and 12 in 2013.
