A world population report has revealed that Pakistan is amongst the fastest growing populations, with its total population estimated to be 220.9 million and an annual fertility rate of 3.6 children per couple.
The world population today is estimated to be 7.8 billion, as disclosed by the 2020 World Population Data Sheet released by the US Population Reference Bureau, Washington.
The report, referring to the COVID-19 pandemic warned that the “population density in urban areas, household size, and population aging contribute to our vulnerability to pandemics”.
South Asia has been placed amongst the fastest growing regions across the world. Within the region, Pakistan and Afghanistan have been named the fastest-growing populations. Compared to Pakistan, Afghanistan has a faster growth rate of 4.5 per couple. However, as the country has a high death rate and low life expectancy the total population of the country is still just 38.9m.
In order to reduce its population, a country needs to bring the growth rate down by 2% per year to reduce the population. The total population of Bangladesh in 2020 is estimated to be 169.8m with a yearly growth rate of 2.3. Similarly, China remains the largest population in the world with a total of 1.424bn people. The country has been able to reduce its fertility rate to 1.5. It is expected that the population of China will decrease by 2050.
India has the second-largest population in the world with 1.4b people. The fertility rate has reduced to 2.2.
