text: 334. Accompanyinq the structural change in production, there has been anintersectoral shlft in the labour force of the developing countries of Africa, asshown in Table 61 below. The percentaEe of the labour force in agriculturedeclined from 80 per cent tn 1960 to 59 per cent in 1979 (the last year for thichdata are available). Horrever, the percentage of the labour force employed inindustry almost doubled over the same period, rising from 2.5 per cent in 1960 tor3.4 per cent in L979. However, since the number of industriar jobs in Africa wasrelatively small at the beginning of the period, even a doubling of the Africanrabour force in industry by l9?9 meant that the actual number of industrial jobscreated has fallen far short of the very large increase in the urban rabour forcedue !o population grorrth and rural-urban migration. As a result, flNost of theincrease in the urban labour force in Africa over this period found onry precarrous employment in the informal service sector.A/ 40/sI9 Eng 1i sh Page I74 Table 61.

analysis: The text discusses the structural changes in the labour force and agricultural sector in developing countries of Africa, highlighting the decline in agricultural output, the shift in employment from agriculture to industry, and the constraints faced by the agricultural sector. The text also mentions the impact of these changes on the economy and the population.
