China will launch two nationwide population panel surveys this year to help strengthen statistical work related to demographic changes in the country and support the population's high-quality development, according to the National Bureau of Statistics (NBS).

The two surveys are to be separately carried out from June 1 to 25 and from Nov. 16 to Dec. 5, according to the NBS.

Residents will be asked to provide basic information, including their name, gender, age, education level, as well as details about their employment, marital status, family births and deaths, and child welfare.

The population panel surveys, an effort to strengthen population statistics work and dynamic monitoring, constitute a critical supplement to population sample surveys in non-census years.
