The government is planning to carry out a nationwide survey into forced sterilization operations ordered under a now-defunct eugenics law, amid renewed scrutiny of the practice, sources said Wednesday.

The results of the survey, which the government had until now been reluctant to carry out, could lay the groundwork for possible compensation for those affected.

Several people who were subjected to procedures under the 1948 eugenic protection law are already moving to seek compensation in lawsuits around the country.
