India’s population was 1.21 billion in 2011, according to the domestic census, which is conducted once a decade. The government had deferred the 2021 census due to the Covid-19 pandemic.
The world’s population was growing at its slowest pace since 1950, having fallen below 1% in 2020, UN estimates showed.
In 2021, the average fertility of the world’s population stood at 2.3 births per woman over a lifetime, having fallen from about 5 births in 1950. Global fertility is projected to decline further to 2.1 births per woman by 2050.
“This is an occasion to celebrate our diversity, recognize our common humanity, and marvel at advancements in health that have extended lifespans and dramatically reduced maternal and child mortality rates,” UN Secretary-General António Guterres said in a statement.
Referring to an earlier World Health Organization report — estimating about 14.9 million deaths relating to the Covid-19 pandemic between January 2020 and December 2021, the UN report said global life expectancy at birth fell to 71 years in 2021 from 72.8 years in 2019, mostly due to the pandemic.
Countries of sub-Saharan Africa are expected to contribute more than half of the increase anticipated through 2050.
However, the population of 61 countries is projected to decrease by 1% or more between 2022 and 2050, driven by a fall in fertility.
