The pink-coloured map showed users the areas where there were the most women aged 15 to 49 as part of the government's drive to reverse a declining birth rate.
A flooding criticism led it to deactivate the site while it endures corrections. People had complained that it treated the birth rate as a problem that only related to women, because there were no pictures of men on the site.
According to feminist campaigner Lee Min-kyung, 24, "I felt so angered that it blatantly showed how the government saw women's bodies as the country's reproductive tools."
South Korean ministers expressed that the website "was established to encourage local governments to learn and compare other governments' benefits and to promote free competition".
Public viewers could also check what benefits local authorities could give them if they had a child, the average marriage age and other information.
Some other methods have also been tried by the country boost the birth rate, including cracking down on illegal abortions and turning off lights in office buildings early to encourage workers to head home.
Actually officials fear a shrinking workforce will hit economic growth because South Korea has one of the lowest birth rates in the world, significantly lower than it was 50 years ago.
