Why did population growth slow in Barbados after the mid-20th century?

After the mid-20th century, the rate of population growth in Barbados slowed significantly due to two primary factors:

• Family Planning: The successful implementation of a nationwide family-planning program helped manage birth rates.1
• Emigration: Steady emigration contributed to the decline in growth, with people moving first to Britain and later to other parts of the Caribbean and North America.1

During this same period, the country also experienced a sharp decline in death and infant mortality rates, alongside an increase in life expectancy to over 70 years.1
