Privacy shakes Japan’s statistics on health and welfare

Abstract

"In 2005 Japan completed its first census after the Personal Information Protection Law went into force in April 2005. The debate about the new law raised privacy concerns for the first time among the public. The newsmedia also provided several examples of possible lack of safeguards in the data collection of sensitive personal information required for the census. The result was the highest non-response rate ever for the Japanese census. Consequently, its accuracy and role as a source for the reliable national statistics for health/welfare policy-making is now critically threatened. In this paper we argue the necessity to adopt specific safeguards to protect personal data in any future census if the trend of increasing nonresponse rates is to be reversed. We provide some suggestions for such safeguards, and criticize the Japanese government’s response of focusing exclusively on the mechanism of data collection as a means of meeting the privacy challenge.
