Linking Vital Events to NILS and NIMS


Aims and Method

• 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


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.

Unlinked individuals increase each year.

Summary of Results

Births

• Catholic births marginally greater than Protestant births

• Increase in births to mothers aged 35 or more

Deaths

• Protestant deaths outnumber Catholic deaths (2:1)

• Even in 2009 - 4% of deaths were to people who lived in a communal establishment in 2001


Future Directions

• Publish tables on NILS website

• Use Linked 2011 Census - Vital Events in NILS/NIMS to update figures
