This means that during this period, agricultural production growth outstripped population growth at a faster pace than what has occurred over the previous 40 years. Growth rates are compound annual growth rates, that is, the annual rate of growth fr) in prediction (QP) required so that production increases from that observed in period t to that in period t*n: 1+r = exp((ln{QPK,) - ln(QPi))/n). It should be noted that if QP in period t+n is abnormally low, the estimated compound annual growth rate will also be biased downwards.
