Average Age of Mothers in Manitoba at Birth (1991-2023)

Between 1991 and 2023, Manitoba has seen a striking transformation in the age profile of new mothers. Teen births (ages 15–19) have dropped dramatically from 10% in 1991 to just 3.3% in 2023. Meanwhile, the share of births to women aged 30–34 and 35–39 has surged. Women aged 30–34 accounted for 34% of births in 2023, up from 23.7% in 1991. Similarly, births to women aged 35–39 have more than doubled.

Aging Into Motherhood: The Rise of Women 40+ Giving Birth

In 1991, women aged 40–44 represented just 1% of all births. By 2023, that figure had nearly quadrupled to 3.7%. Births to women 45–49 also began appearing in the data after 1994, reflecting advances in fertility technology and changing family planning norms.

Key Takeaways

• Teen births have dropped by more than two-thirds.
• 25–29 years remains a dominant age group but is slowly being overtaken.
• Older mothers (35+) now make up a much larger share of all births.
