Urbanization has occurred in numerous developing countries since World War II and this trend is expected to continue. Urbanization is the increase in the proportion of people living in towns and cities. It occurs because people move from rural areas to urban areas, which usually occurs when a country is still developing. There are many different causes of urbanization. People living in rural areas are drawn to the city, because they often believe that the standard of living in urban areas will be much better. Urbanization has its pros and cons and affects every developing country differently. Three positive effects that urbanization has had on Costa Rica are: Less distances to travel and decrease in transport cost, growth in trade and commerce, and increase community resources. When population is concentrated in cities people have less distance to travel to work and for most other purposes. Urbanization helps the nation's business sector. Rural people come to the urban places with their goods. In Costa Rica growth in trade was a major positive in urbanization, because they are large exporters of bananas, coffee beans, and pineapples to name a few. Inspired by the growth of Los Reyes, multiple residential developments are being built in vast areas. It includes a combination of residential solutions in large areas with other services like a club, swimming pool, golf, tennis and football facilities. Three negative effects that urbanization has had on Costa Rica are: the decrease in rural population, increase in population in urban places, and unemployment increases in urban areas. The decrease in rural population effects the agricultural productions due to shortage of workers in rural areas. If all of the workers move to the urban areas searching for better job opportunities then the work that was once done is no longer being done leading to decrease in goods to be exported. The increase in population in urban places pressurize water and sanitation facilities. It results in environmental pollution and health hazards. The more individuals that move to urban area created more competition for available jobs. (Alesina & Dollar, 2000) Costa Rican conditions have improved: ordinary citizens live longer, healthier lives; are better educated; have far higher incomes; and live in a vibrantly democratic society. A high-way built largely with foreign aid now links the formerly isolated central part of Costa Rica to both its coasts and to neighboring countries Nicaragua and Panama. Most people lived in simple one or two room houses made of wood, and now most houses in both communities were now made of concrete, with concrete or tile floors. All had electricity, and nearly all had piped water and indoor plumbing. Health conditions have improved dramatically, as Costa Ricans were brought into modern medical-care networks. Nearly all births now take place in hospitals, mainly through the social security system, to which more than 70 percent of households are affiliated. Communication with the outside world was revolutionized. While less than 5 percent of the households had radios in 1950, more than 80 percent in each village owned color televisions in 1995. (Chong, Gradstein & Calderon, 2009) The efforts to reduce urbanization problems within Costa Rica through the use of foreign aid were definitely successful, but like anything there are still some things that need to be worked on. For example modern conveniences may become a source of frustration. For example, electricity quickly becomes “essential.” Once this happens, any power interruption becomes a source of distress, people are worried about the future. People worry about politicians in the capital city, about powerful economic interests that might hurt the small producer or the employee, about deterioration in the quality of education for their children. In sum, they worry about the same things most Americans worry about not an occasion for contemplation of how beneficial it is to have electricity most of the time. Costa Rica has come a long way with the help of urbanization and foreign aid. The government has used the aid to better serve the people of Costa Rica. There is still much to be done. The economic assistance to Costa Rica significantly contributed to Costa Rican welfare.
Costa Ricans are healthier, wealthier, and better educated than they would have been without foreign aid. It continues as a vibrant democracy with respect for human rights, a model for other countries. After a rocky period in the early 1980s, its economy has successfully adapted to a changed world economy. It is a world leader in ecosystem management.
