• Aims– Vital Events Statistics by 2001 Census variables – High User Demand (e.g. Education Area-Plans) – Highlight potential use of the NILS & NIMS
• Method– Vital Events data linked to NILS/NIMS (SQL)– Tables built in Stata– Tables exported to MS Excel
www.nisra.gov.uk/demography www.qub.ac.uk/nils
Births Linkage Process
100%(207,905)
• 207,905 births to NI mothers (2001-9)
NILS Match • NILS 28% sample linked (1-1 match)
Census Match• NILS data linked to 2001 Census.
