The type of work which people do is constantly changing as man develops and modifies his way of living. One hundred years ago, the vast majority of people worked in agriculture, but now less than half the world’s population do so. In fact, in only ten years major changes have been seen in the percentage of the workforce employed in various sectors.
Figure 1 shows the overall distribution of jobs in the three major sectors in 2005: agriculture, industry, and services. It can be seen that almost the same percentage of people worked in services as in agriculture, whereas only around 20% were employed in industry. In the ten years leading up to 2005, substantial changes in employment took place, reflecting changes in technology and lifestyle.
As Figure 2 illustrates, a significant change took place in the agricultural sector. In 1995 43% of the world’s workforce was employed in agriculture; by 2005 this number had fallen to 40%. The largest decline was in South-East Asia and the Pacific, where the figures dropped by 12%.
Similarly, in industry the workforce fell by two per cent globally. Manufacturing was the largest sub-sector of industry to be affected. However, these figures represent only an overall picture, as some countries saw industrial employment actually rise by one per cent. This was particularly noticeable in certain South-East Asian countries, where low wages and fast industrialization have enabled countries like China to become world leaders in manufacturing. In other sub-sectors of industry such as textiles, the global workforce dropped from 14.5 million in 1990 to 13 million in 2000, as increasing automation reduced the number of employees needed.
However, one sector saw an increase. The service sector employed 34% of the workforce in 1995, but by 2005 this had risen to 40%. This extremely varied sector includes the retail trade, tourist-related services such as hotels and restaurants, as well as transport, communications, finance, property, research and development, education, and health care. The largest developments were seen in the new Information and Communications Technologies (ICTs), which have grown rapidly since the 1990s. The developments in ICTs have had a huge impact on jobs in all sectors, as computer technology has radically affected the way in which work is done. The means of production, distribution, and communication have all been transformed. The number of jobs in IT as a percentage of all jobs in the service sector is represented in Figure 3.
Although there was a slight drop in the numbers of jobs in IT in the mid-1990s due to a recession, the overall trend was upward. As technology spreads across the world, this rise in jobs will continue. It is estimated that one in twenty new jobs will be in ICTs in the future.
Economists predict that these overall tendencies will continue. There will be a further increase in service-sector employment, and in particular in ICTs, but health care and education will also benefit from more jobs. At the same time, fewer people will be employed in industry and agriculture.
