The tables on pages 57-68 present 34 statistics related to sorghum and millet production and consumption, as well as some basic economic indicators, for countries where the 1992-94 average production of either sorghum or millet exceeded 50 000 tons. Zeros represent negligible quantities consumed, produced or harvested.

Unless otherwise indicated, the regional aggregates (pages 67-68) include all the countries of a particular region for which information was available. Regional totals were calculated by summing the values for all countries in a region and then calculating the mean value. Thus, regional totals may be slightly different from the sum of the average values for each country.

**Data sources**

*Variables 1 and 2:* FAOSTAT.PC (1995) demographic database.

*Variables 3:* World Bank World Development Report (1993).

*Variables 4 to 34.* FAOSTAT.PC database of production and utilization statistics (1994).

**Growth rates**

Growth rates (variables 15 to 20 and 29 to 34) were calculated using the exponential growth rate,

Y = b0(e^{b}_{1}^{t}) linearized as ln Y = ln (b_{0}) + b_{1}t

where ln Y = natural logarithm of variable Y, t = time period (years), and b_{1} = growth rate of Y.
