In a few words, what is Population?
Over the last two centuries, global population has grown exponentially, from 1 billion people in 1820 to over 7.7 billion people today. Factors such as improved medical care, increased agricultural production, and reduced death rates are all contributors to population growth. Population growth has presented society with many challenges, from environmental degradation to economic inequality.
Population Growth: Exploring the Exponential Increase in the Global Population
Population Growth: The increase in the number of people that inhabit a given area. Demography: The study of human populations, including their size, composition, and distribution. Exponential Growth: A type of growth that occurs in populations that reproduce at a consistent rate.
The world population is projected to reach 9.7 billion people by 2050. The majority of population growth is expected to take place in the poorest countries around the world. The population of Japan is expected to decrease by 20% by 2050 due to a low fertility rate.
