People are migrating to urban areas for many reasons, including agricultural technology, industrial technology, and the hope of changing ones economic circumstances.
Agricultural technology has decreased the need for agricultural workers. Improved transportation, tools, fertilizer, and genetically modified crops mean fewer farmworkers harvest more food. This decreased need for farm employment drives many farmworkers into cities in search of jobs.
Industrial technology has created many jobs unique to urban areas. Developing countries often have resource-based economies, meaning most people make their living from agriculture, timber, mining, or other harvesting of natural resources. These natural resources are most often located in rural areas. As developing countries expand the use of industrial technology, they often shift their focus to a service-based economy. Service-based economies use industrial technology to provide finished goods and services to people inside and outside their countries.
India, for instance, is a country where many people practice agriculture in rural areas. As the Indian economy develops, however, more people migrate to urban areas like Bangalore to work in the technology industry. Instead of providing the raw materials (metals) for computer chips to nations like the United States, Indian companies now manufacture the computer chips themselves.
Centers of learning, such as universities, hospitals, and regional government, are usually located in urban areas. Many rural residents travel to cities to take advantage of economic opportunities there.
The cost of living in urban areas is usually much higher than in rural areas. It costs more to rent a house, buy food, and use transportation. For this reason, wages are usually higher in urban areas. The search for higher wages is another reason people migrate from rural areas.
In the United States, rural areas take up about 98 percent of the country but are home to only 25 percent of the population. In Ethiopia, a less-developed country where agricultural jobs are much more common, 87 percent of the people live in rural areas.
