The cumulative salted fish consumption up to the specified time point was estimated by aggregating annual salted fish consumption per capita estimates in all years prior to that year up to 1991. (a) Cumulative salted fish consumption per capita was estimated from FAO commodity statistics on fish, dried, salted or smoked. (b) Cumulative salted fish consumption per capita was estimated from Hong Kong trade statistics on dried fish, whether or not salted but not smoked.
