"Employee social security coverage rate refers to the proportion of the labor force in a country or region that participates in the social security system. The social security system is a welfare program provided by the government or employers that provides medical care, unemployment, retirement, disability and maternity for the labor force and other guarantees.

The popularization of the social security system can help the labor force avoid poverty, improve the quality of life and social welfare, and also play an important role in the stability and development of a country or region. Therefore, the level of employee social security coverage has become one of the important indicators of national and regional economic and social development.

Globally, there are large differences in employee social security coverage. In some developed countries and regions, such as EU countries, North America and Australia, the social security coverage rate of employees is relatively high, reaching more than 90%. However, in some developing countries and regions, due to factors such as economic conditions and policy restrictions, the social security coverage of employees is relatively low.

Improving the social security coverage of employees requires the joint efforts of the government, employers and labor force. The government needs to strengthen the construction and improvement of the social security system, provide relevant policy support for employers, encourage employers to participate in the social security system, increase publicity and education for the labor force, and increase the labor force's security awareness and willingness to participate in insurance.

In short, the improvement of employees' social security coverage is an all-round project, which requires the cooperation of the government, employers and labor forces to jointly promote the construction and improvement of the social security system and provide more comprehensive and effective social security guarantees for the labor force.
