The number of people from Ireland who travelled to England and Wales for abortions last year declined.
Official statistics from the UK Department of Health show that 194 women and girls travelled from the Republic during 2020, down from 375 in 2019.
The figures also show that 565 people who had abortions in England and Wales last year gave addresses on the island of Ireland.
371 travelled for abortions from Northern Ireland.
32% of abortions for those resident in Ireland were carried out under 'Ground E' which permits abortion in the case of foetal abnormality.
The Abortion Rights Campaign has pointed out that people who travelled did so in a year that was dominated by Covid-19 and lockdowns.
Spokesperson Joanne Neary said that despite the legalisation of abortion in the Republic, and the decriminalisation of abortion in Northern Ireland, "there clearly remain grossly unacceptable gaps in the service provision on this island".
Eilís Mulroy of the Pro Life Campaign called for "an urgent debate" on how the new law is operating with a view to finding ways to "reduce the spiralling numbers of abortions taking place".
As part of the Termination of Pregnancy Act the legislation must be revisited after three years.
The National Women's Council used statistics from 2019 in a recent report to mark the 3rd anniversary of the referendum on the Eighth Amendment.
It showed that one in 10 GPs and 10 out 19 hospitals were providing abortion services.
The report said women in rural areas, particularly in the north west and those from marginalised backgrounds, faced extra challenges in accessing services.
