With death rates decreasing, the research issued for World Population Day predicts that the global population will increase from its current projection of 8 billion by November 15 to 8.5 billion by 2030 and 10.4 billion by 2100.
The domestic census of India is carried out once every ten years, and it was estimated that there were 1.21 billion people in the country in 2011. Because of the Covid-19 outbreak, the government postponed the next census in 2021.
UN projections suggested that by 2020, global population growth has slowed to less than 1 percent.
Average global fertility decreased from 5 births per woman in 1950 to around 2.3 births in 2021. Fertility rates are predicted to fall further, reaching 2.1 births per woman worldwide by 2050.
United Nations Secretary-General António Guterres said in a statement, “This is a time to celebrate our diversity, acknowledge our shared humanity, and marvel at improvements in health that have extended lifespans and substantially decreased maternal and child death rates.”
An increasing population is a sobering reminder that we all have a stake in the well-being of our planet and should “think on where we still fall short of our promises to one another,” he added.
According to the UN study, global life expectancy at birth dropped to 71 years in 2021 from 72.8 years in 2019, mostly owing to the Covid-19 epidemic.
According to the UN, by 2050, eight countries (the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines, and the United Republic of Tanzania) would account for more than half of the anticipated growth in the world population.
Sub-Saharan African countries are predicted to account for a disproportionate share of the projected growth until 2050.
There are 61 nations whose populations are expected to shrink by 1% or more between 2022 and 2050 due to declining fertility rates.
