What was Life span in 1947?

In 1947, the global average life expectancy was significantly lower than today, typically around 48 years. This figure varied by region, with developed countries averaging closer to 65 years, while many developing nations had life expectancies below 40 years due to factors such as disease, malnutrition, and lack of access to healthcare. Advances in medicine and public health in subsequent decades have contributed to the substantial increase in life expectancy worldwide.
