Data on morbidity and mortality from oesophageal cancer (EC) over the 25 years from 1959‐1983 indicate that this malignancy has been the commonest cause of death in Linxian (LX) county during that period, accounting for 16% of deaths from all causes and 65% of deaths from cancer. Whereas incidence and mortality of EC were high but stable during this period, a decline in mortality has been noted recently in younger age groups, coinciding with an improvement in nutritional standards. Cohort analysis for the period 1879‐1954 demonstrates mortality peaks among individuals born late in the last century and early in the present one. It also shows that a decline in mortality appears to have started among natives of the county born during the period 1935‐1954.
