World Population Day

In News 
  • On World Population Day(11 July), the United Nations released a report (world population prospectus) projecting India to surpass China as the world’s most populous country next year.
  • The forecast by the UN Department of Economic and Social Affairs said the world’s population is growing at its slowest pace since 1950.
Major Findings 
  • According to World Population Prospects 2019, China with a 1. 44 billion population and India with 1.39 billion are the two most populous countries in the world, representing 19 and 18 per cent of the world’s population, respectively.
  • India taking over China: However, by around 2023, India’s population will overtake China to become the most populous country with China’s population projected to decrease by 31.4 million, or around 2.2 per cent, between 2019 and 2050.
  • Population to reach eight billion: The UN forecast also stated, that the world’s population is expected to reach eight billion.
  • Net drop in birth rates: While a net drop in birth rates is observed in several developing countries, more than half of the rise forecast in the world’s population in the coming decades will be concentrated in eight countries.
  • Eight countries are the Democratic Republic of Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and Tanzania.
  • Challenge to SDGs: Many are projected to double in population between 2022 and 2050, putting additional pressure on resources and posing challenges to the achievement of the UN’s Sustainable Development Goals (SDGs).
  • Older age population growth: The population of older persons is increasing both in numbers and as a share of the total.
  • Sustained drop in fertility: A sustained drop in fertility has led to an increased concentration of the population at working ages (between 25 and 64 years), creating an opportunity for accelerated economic growth per capita.
  • Migration: International migration is having an important impact on population trends in some countries.
  • Over the next few decades, migration will be the sole driver of population growth in high-income countries.
  • The Covid-19 pandemic has had significant demographic consequences affecting all components of population change, including mortality, fertility and migration.
