In the 1970s, Fujian Province conducted a retrospective survey of the deaths of residents in the province from 1973 to 1975. In the 1980s, a retrospective sample survey of the deaths of residents across the province was conducted from 1986 to 1989, and 14 counties and cities were selected by stratified cluster random sampling.
