Data for April shows that South Korea recorded more deaths than births for the 18th month in a row.
According to Statistics Korea, the number of births in April was at around 22,800.
That's a decline of two.two percent on-year.
More babies were born in the cities of Busan and Gwangju, but not in Seoul or Daegu.
Around 25-thousand people died in April meaning the country's population decreased by 22-hundred people.
The government has been spending a massive amount of funds since 2018 to tackle the low birthrate crisis offering financial aid to those who give birth.
But, experts say that the funds cannot stop the falling population, and added that the government has to work more on childcare and education policies.
Population movement decreased for the fifth month in a row in May as not many people are buying new houses.
Data from Statistics Korea shows that 557-thousand people moved to other regions of the country leading to a two.two percent fall.
"The decline in population movement is related to housing business cycle indicators. The sales of houses over the last three months has fallen."
Meanwhile, Finance Minister Hong Nam-ki said on Wednesday that without any special measures, South Korea will face a so-called "agequake" social issues arising from an aging society starting from 2030 to 2040.
And added that the economically inactive should enter the labor market to help the country's economy.
