Social health insurance coverage and financial protection among rural-to-urban internal migrants in China: evidence from a nationally representative cross-sectional study

Improving availability and portability of health insurance would promote financial protection for IMs, and further facilitate achieving universal health coverage in China and other countries that face migration-related obstacles to achieve universal coverage.
