Eastern, Lusaka, and Southern provinces. With the exclusion of southern areas of the Western
province, the northwest region is generally situated in areas receiving in excess of 1,100 millimeters
(or 44 inches) of annual precipitation, while the provinces in the southeast region receive 1,000
millimeters (or 40 inches) of rainfall per year or less.
Data in the commercial farm series are further disaggregated by farm size categories, but the
categories have not remained the same over time. In 1975-76, six categories were used: 0-79
hectares, 80-199 hectares, 200-399 hectares, 400-799 hectares, 800-1,999 hectares, and 2,000+
hectares. This classification system was maintained until 1986-87 when the number of categories was
reduced to four—0-199 hectares, 200-799 hectares, 800-1,999 hectares, and 2,000+ hectares—and
remained so through 1989-90. To ease computation burdens, data series were further consolidated into
three categories for purposes of growth rate analysis: small farms (less than or equal to 199 hectares),
medium farms (200-1,999 hectares), and large farms (2,000+ hectares).
