Moreover, life expectancy statistics are skewed due to historically high infant mortality rates.

In the 1920s MacMurchy waged a campaign against the then high infant and maternal death rates.

The combination of these statistics has unfortunately resulted in relatively high infant and maternal mortality rates for an industrialized nation.
