Sustainability Challenge Associated with Urban Dynamics Essay

Sustainability Challenge Associated with Urban Dynamics - Essay Example Urban sprawl did not start recently. It started a long time ago. Here, we find that the rich had a desire to seek the pleasure of living in secluded areas with low population densities. The Chinese and the Romans historically practiced this habit of the rich living in suburbs with protective walls (Karen & J. Marshall, 2009 p 2). The sprawl in cities and towns always occur when the city has reached peak economic growth. Therefore, at first population density in the city center is normally high. As the city develops, this density reduces as people move away from the center due to improved services such transportation.Scholars, planners, public officials and community activists have offered many possibilities that cause urban sprawl. These causes include lack of comprehensive planning, rapid population growth, consumer preferences and subsidized infrastructure improvements.Lack of comprehensive planning is one of the principal urban sprawl causes. Poorly planned developments in the out skirts of urban centers often happen due to officials planning in a densely populated urban area without consulting nearby communities (Chiara et al, 2010, p 3). The resultant less densely populated regions demand high expenses for infrastructural development. Rapid population growth is another key factor responsible for urban sprawl especially in the Southern and Western United States regions (Klaufus, 2010, p 5). When the population of a city increases, people will tend to move spreading. further from the city centres. When communities in the urban fringes enjoy subsidies of roads, sewers and water from municipalities, unplanned developments easily sprawl in the regions. Some people prefer living in isolated places with much space for large homes, large yards and more bedrooms. This desire means movement of people away from densely populated city centres. The movement results in spreading of cities and progressively reduction in population density away from the city centre. A lack of understanding of unplanned growth consequences may also lead to urban sprawl. The government in most cases has not taken a consideration of the implications of urban sprawl. The government’s action of allowing developers to do as they wish may also cause urban sprawl. When people over depend on automobiles for transportation, urban sprawl may also result. Developments in the urban areas involve the use of materials such as stone, cement and asphalt. Subsidies on automobiles play a critical role in the spreading of urban sprawl. This, according to Hanson (1992), enables automobile owners to incur low costs of

The Participation Rate Research Proposal Example | Topics and Well Written Essays - 1500 words

The Participation Rate - Research Proposal Example Individuals are considered to be unemployed, for the purposes of the unemployment rate, if the individual is actively looking for work, but is unemployed. Workers who are out of a job, due to a temporary layoff, but expected to be recalled, are considered to also be unemployed. During the survey week, the individual must be not employed, available for work and taking active steps to find work, in order to be counted in the unemployment rate. Individuals who do not count in the unemployment rate are individuals who are discouraged, and no longer actively looking for work. ...The individuals who would not be included in the participation rate are those who are unemployed, but not actively looking for work, because they are discouraged. Also not included would be individuals who are not labor force. These are individuals who are not looking for work because they are going to school, are retired, are stay at home mothers or individuals with other family obligations, are confined to nursi ng homes, mental institutions or prisons, or inactive duty military (Bureau of Labor Statistics). B. Charts of Participation Rates for Females and Males (All Figures Come from The Australian Bureau of Statistics) 1954 In this case, the Australian Bureau of Statistics did not publish very much information which can be gleaned about males versus females and the participation rates. It did not publish information, which it did in later editions, that detailed the employment rate, the unemployment rate, the unemployment numbers and employment numbers, etc. Therefore, the chart below has much more sparse information than the later ones will. In 1954, the total number of men who were employed, including defense forces, was 2,821,000. The number of women who were employed, including defense forces, was 826,000. During this same period, there were 41,000 males who were unemployed and 14,000 females who were unemployed. The unemployment rate was 1.8% for males in this year, and 1.9% of femal es. Therefore, the total number of men who were participating was, for the year, 1954, 2,862,000. The total number of females participating for that year was 840,000 (Australian Bureau of Statistics). 1967 In 1966, there were a total of 3,351,800 males who were employed. There were 32,900 males who were unemployed.
