The level of poultry production for each region is given in the first column of table 4. It is the 1998 estimate of poultry meat production (obtained from the Food and Agriculture Organization FAOSTAT database). The level of poultry production in the two composite regions is determined by first identifying which countries are net poultry exporters in FAO trade data. Then, the level of poultry production in the ROWE region is the sum of production in these exporting countries. Poultry production for the ROWM region is obtained by subtracting the quantity of poultry meat produced.
