Singapore registered record dips in its population numbers over the past year as the impact of Covid-19 pandemic restrictions and conditions hit home, the Government's annual Population in Brief report revealed on Tuesday (Sept 28).

Singapore's total population as of June fell for the second straight year, down to 5.45 million from 5.69 million in 2020. This 4.1 per cent decrease is the largest percentage decline - and only the third instance of negative growth - since 1950, according to data from the Department of Statistics.
