Ontario Birth Death Marriage Counts By Month

Ontario government data tracks monthly counts of births, deaths, marriages, and stillbirths registered since 1994. Preliminary figures for 2024 and 2025 are updated quarterly as registrations are completed. ServiceOntario compiles these statistics under the Vital Statistics Act.

Use Cases

• Modeling monthly birth rate trends using time-series data from 1994 onward.
• Analyzing correlations between death counts and seasonal factors across calendar quarters.
• Tracking marriage registration volumes over time for demographic and social research.
• Comparing preliminary and final counts for births and deaths to understand reporting lags.

Strengths

• Time series spans over 30 years from 1994 to present.
• Data includes four distinct event types: births, deaths, marriages, and stillbirths.
• Quarterly updates provide ongoing data refresh for recent years.

Limitations

• Preliminary data for 2024 and 2025 is incomplete and may undercount events.
• Final annual counts are published with a significant delay in the Registrar General's Annual Report.
• Data completeness depends on registration timeliness from varied sources, introducing potential lag bias.
