Look at the figures for the proportion of people involved in agriculture, as shown in the pie charts below.
The pie charts compare the percentage of agricultural workers in developed and developing countries in 1950, 1990 and 2025. Basically, the figures show that developed countries always have lesser proportion of people engaged in agriculture than developing countries and with time the proportion decreases for both (countries).
In 1950's, a large percentage of people, i.e. 81.1%, in developing countries were engaged in agriculture. After 40 years in 1990, the figure dropped to 59.6% and it is estimated that the numbers will continue to fall. In fact, the percentage may decline to 37% in 2025.
The trend is same for developed countries. In 1950's more than 1/3 of the population was involved in agriculture but by 1990's, the proportion dropped by almost 4 times to 8.4%. The proportion has been estimated to slump to 2% by 2025. This decrease in agricultural workers might decline the agricultural productivity. On the second thought, if technology does replace the labourers the rate of unemployment will increase.
Corrected Version
The pie charts compare the percentage of agricultural workers in developed and developing countries in 1950, 1990 and predicts for 2025. The figures show that developed countries always have a lesser proportion of people engaged in agriculture than in developing countries and with time the proportion decreases for both country areas.
In 1950, a large percentage of people, i.e. 81.1%, in developing countries were engaged in agriculture. After 40 years, the figure dropped to 59.6% and it is estimated that the numbers will continue to fall. In fact, the percentage may decline to 37% in 2025.
The trend is the same for developed countries. In 1950, more than one third of the population was involved in agriculture, which matches the forecast for developing countries in 2025. By 1990, the proportion dropped by almost 4 times to 8.4% and the proportion has been estimated to slump to 2% by 2025.
