Reasons for declining birth rate
Decline in infant mortality rate
When infants died parents had more to replace them, now as infants survive parents have fewer children
Infant mortality rate fell due to
• Improved housing, better sanitation, reduced infectious disease
• Better nutrition, including that of mothers.
• Better knowledge of hygiene, child health and welfare.
• A fall in the number of married women working may have improved their health and that of their babies.
• Improved services for mothers and children, such as antenatal and postnatal clinics.
