Study Notes
Global Population Growth
- The global population has increased drastically from 2.5 billion in 1950 to over 8 Billion currently and is expected to reach around 10.4 billion by the end of the 21st century
- Population Pyramids are used to visualize the distribution of a population by age and gender
- The shape of population pyramids can provide insights into demographics and the health of a population.
- In 1950, the pyramid had a wide base due to high birth rates and a narrow top due to high death rates
- The child mortality rate is declining and the pyramid is becoming less narrow above the base.
- The number of children born has increased since 1950, and the mortality of children has decreased at the same time.
- While the number of children born will increase slightly then decline, the number of people of working age and old age will increase significantly.
- There will be fewer children born by the end of the century than today.
- The base of the population pyramid for 2100 is projected to be narrower than the one in 2018.
Demographic Dividend
- In the coming decades, poorer countries will benefit from a "demographic dividend," where the share of the working population increases.
Population Health
- The global population is becoming healthier and the proportion of older people is increasing.
- A more box-shaped population pyramid reflects a healthier population with a low death rate during younger ages.
Global Population Trends
- The global population is expected to become more box shaped by 2100, indicating a healthier population with a low death rate and an aging population.
- From 1950 to today, the global population growth was a widening of the entire pyramid, with an increase in the number of children.
- In the future, global population growth will be characterized by a 'fill up' of the population, with a lesser increase in the number of children followed by a decline, but a significant increase in the proportion of people of working age and old age.
- This shift is driven by decreasing death rates and improved global health leading to longer life expectancies.
