There were 2,000 fewer abortions reported to the Department of Health last year compared to 2020.
The third annual report on terminations shows there were 4,577 in 2021.Under the current law, GPs and hospitals must notify the Department of Health of an abortion and the grounds it was approved.
Latest figures show 4,513 early medical abortions were notified to the department last year.
There were 53 abortions carried out on the grounds of a fatal foetal anomaly.
Nine due to a risk to the life or health of the mother, and two on the grounds of a risk to the life or health of the mother in an emergency.
The Department says there was also a significant decrease in notifications from May through to August.
It says this coincided with the cyberattack on the HSE - and says that's likely to have led to the large reduction in notifications during that period.
