Presents the numbers of SINGLETON and MULTIPLE births each year for the period 2006 to 2015. The Perinatal Statistics Report 2015 is a report on national data on Perinatal events in 2015. Information on every birth in the Republic of Ireland is submitted to the National Perinatal Reporting System (NPRS). All births are notified and registered on a standard four part birth notification form (BNF01) which is completed where the birth takes place. Part 3 of this form is sent to the HPO for data entry and validation. The information collected includes data on pregnancy outcomes (with particular reference to perinatal mortality and important aspects of perinatal care), as well as descriptive social and biological characteristics of mothers giving birth.
