For legacy birth record data (formerly collected in the Niday Perinatal Database), there is a complete six-year dataset available for analysis. Ascertainment improved from approximately 89% of hospital births in Ontario in the 2006–2007 fiscal year to 100% of hospital births in the 2010–2011 and 2011–2012 fiscal years. New data elements, pick-list values, and updated terminology were included in the BORN Information System for the 2012–2013 dataset and beyond, which are not available in the legacy dataset. Please note that it will not always be possible to map certain legacy data elements and pick-list values to the new BIS data dictionary. Niday Legacy Data Dictionary (2006–2007 to 2011–2012)
The Midwifery Legacy dataset (2006-2007 to 2011-2012) is also available.
