The claim
外国人は社会保障にただ乗り?
Original review summary
The review says that although foreign residents have higher national health insurance premium delinquency, their share of medical costs is lower than their share of enrollees, and foreign households receiving livelihood assistance are a small share overall. It concludes that the broad claim of foreigners free-riding on social security is not supported by the figures it examines.[S1]
