The difference in level of education and social status can lead to a heterogeneous state. Heterogeneity can continue and spur competition, especially if the population in many growing cities and with the schools there was a variety of diverse specialties in the field of the type of skills or livelihood.
Differences socio-economic status or cultural nature can lead to "individualism". Properties of the pure mutual cooperation has been very rarely can be found in the city. Direct face-to-face interaction and in the size of a long time been rare, due to communication by telephone has become the interface that is no longer a luxury. Moreover, because the education level of urban residents was high enough, then all problems solved cultivated individually or privately, without asking for consideration of other families.
The flurry of each resident within the city that is high enough to reduce its attention to others. If this is too much then they will be able to have a nature indifferent or have less social tolerance. In the city this problem can be overcome with the institution or foundation engaged in areas of society.
Population density in cities is in general may be quite high. Usually exceeds 10,000 people/km2. So, physically on the road, in the market, in stores, in theaters and at other places adjacent to the town but far apart in terms of social, because of different needs and interests.
Differences in status, interests and circumstances of city life conditions have an influence on different scoring systems of the symptoms that arise in the city. Assessment can be based on economic background, education and philosophy. Changes and variations may occur, because there is no exact structure of the same city or state.
One thing that needs to be added as an explanation is an understanding of the term "neighborhood". In the sense of "neighborhood" contained elements of physical and social, because the elements are woven into a single unit is a unit of life in urban governance. Elements such as school buildings, building shopping malls, markets, open areas for recreation, railways, automobile roads and so on. These elements lead to the activity and bustle of everyday life. So, the real "neighborhood" This is not a new thing for us. In the city there are many units or groups of "neighborhood", because "neighborhood" is limited by certain criteria, among others:
- This environmental achievement is limited to the distance between someone with a shop or school, for example, can be done by foot.
- If someone is forced to use the vehicle, then the job does not need to go through heavy traffic and crowded.
- In terms of population, then one unit of "neighborhood" is inhabited by 5,000 to 6,000 people. For places in Indonesia this figure would not be the same and will probably show a larger number.
A unit of "neighborhood" can be formed if there was braided and social interaction among fellow townspeople. Unit or group of "neighborhood" can occur by itself, but can also occur with an urban development plan, by plotting the areas of special living environment and meet the requirements of practical and fun. The increase in both city dwellers from the city dwellers as well as from current residents who come from outside the city resulted in the increase in residential housing, which means reduction in vacant areas within the city. Increasing number of city kids who become more and more also required school buildings. Increased student and the student also means increasing the number of bicycles and motorized two-wheeled vehicles. The shops. Food stall or restaurant continues to increase so that more and accelerate endless vacant lots in the city. The city had to be expanded gradually away from the city.
