All % data provided here has been calculated by 'bump2babe: The Consumer Guide to Maternity Services in Ireland'. Maternity units provided bump2babe with numbers of mothers for the various categories and we calculated the percentage rates based on the numbers of mothers who gave birth in the unit. We are not responsible for any inaccuracies in the figures given to bump2babe. The guide has highlighted and raised concerns about differences in data recording and reporting abilities in the 22 maternity units in Ireland.
