A new report published by the UK's Department of Health shows that 23 women with addresses in County Longford had abortions at medical facilities in England and Wales in 2015.
That figure accounts for one per cent of the 3,451 Irish women who had terminations there last year.
Meanwhile 17 women provided home addresses situated in Co Leitrim, while there were 25 from Roscommon, 32 from Cavan, and 56 from Westmeath.
Irish women were by far the highest group of non-UK residents undergoing the procedure, followed by France with 65, and Malta with 58.
A total of 231 women declined to provide their county of residence.
