2 Urban population dynamics Between 1990 and 2000, the total population of the western United States increased from 52,786,082 to 63,197,932 and increased by 19.7%. This is the fastest of the four domestic regions (Perry and Mackun, 2001). This also reflects the trend of population growth after the Second World War, which is characterized by the rapid growth of several Southwest major cities. These "magnets" cities are those who want to use prosperous economic opportunities in this area, people who want to live in "quality of life" and warm facilities, and wilderness
Currently, about half of the world population lives in urban areas The United Nations World Urbanization Forecasting Report shows that by 2030 60% of the world population lives in urban areas. As a result, social scientists are increasingly focused on specific types of social mechanics that develop in the urban environment. Social scientists pay attention to social exchanges in urban areas because cities have the unique ability to summarize many cultural backgrounds. Due to its dense population, economic problems and power dynamics in narrow spaces where resources are scarce are being strengthened. In addition, with new ideas, people and things continue to flow through urban areas, and cities function as diverse areas of economic relations and other kinds. Therefore, people there must deal with the new influences, and often have to bring dominant culture to the forefront. What is the value of a group of specific people?
The definition of urban dwellers and urban users is based on the relative importance of the natural and developed regions to demographics. The survival of urban residents in urbanized landscapes has nothing to do with natural areas (ie whether population growth rate is 1 regardless of immigrants from natural areas, such as knitting spiders etc. ). Urban producers should be aware of breeders (such as northern brown striped ears) that exist only as non-breeders in the urban environment (ie as non-breeding seasons or as forage only) or only for spread of adjacent natural areas .
As our population rapidly increases to urban areas, the situation of urbanization is changing all the time. The dynamic state of the urban environment creates an exciting architect's path to everything from economic and demographic changes to sustainable development. While this is an important responsibility in our profession, it is a rewarding responsibility and requires extensive adaptation and problem solving. The tradition and history that our society presents through architecture is not only a glimpse of the past but also a culture of understanding our culture as discipline. We can not deny building protection and repair as a challenge; it is impossible to please everyone. Very beautiful solutions are often used, but media often positions recovering behavior as "massacre of heritage".
