The ethnic diversity in metropolitan areas is characteristic of the United States. Levels of ethnic diversity in certain metropolitan areas are different, and the economic status of these areas is also different. Thus, there is a question about the presence of the obvious relationship between the levels of ethnic diversity and the median household income in these areas.
In spite of the fact that metropolitan areas are characterized by the highest degrees of economic development in the United States, there are few facts presented in the literature to support the idea that the direct cause of economic progress is the extreme ethnic diversity typical for the areas. Furthermore, it is difficult to conclude about the role of the Black, Asian, and Latino populations as separate ethnic and racial groups in affecting the levels of the household income in the U.S. metropolitan areas.
Referring to the hypothesis that there is an obvious connection between levels of the ethnic diversity in metropolitan areas and the household income, it is possible to state that this hypothesis is confirmed for the Asian population living in the U.S. metropolitan areas.
The results of using a scatter plot with a trend line indicate that the high density of the Asian population in the metropolitan statistical areas is associated with levels of the household income typical for these areas. Thus, the highest household income amounts are characteristic of the areas where the percentage of the Asian population can be described as high.
However, the hypothesis is not confirmed for the data presented on the Black and Latino or Hispanic populations. It is important to note that the percentage of the Black population is in a negative relationship with the median household income that is typical for the U.S. metropolitan areas.
This result means that the increases in the number of the Black population in the U.S. metropolitan areas do not lead to the increases in the economic status of these territories. The changes in a number of the Hispanic population also do not obviously influence the economic development of the metropolitan areas because there is no correlation between the percentage of the Hispanic population and the household income.
This research examines how high degrees of ethnic diversity in the U.S. metropolitan areas can be associated with active economic development in these areas. Thus, it is possible to conclude that the factor of ethnic diversity can be discussed as the indirect factor to influence the changes in household income. The reason is that the current research presents the evidence to state that only the Asian population plays a significant role in contributing to the economic progress of the metropolitan areas in the United States.
Thus, the hypothesis is confirmed only in relation to one ethnicity living in the U.S. metropolitan areas. The limitations of this study are in the fact that it is rather problematic to analyze how the highest level of racial diversity in metropolitan areas can affect household income because of the possibility to present the results for only separate ethnic and racial groups living in the U.S. metropolitan areas.
However, this study contributes to concluding about the different role of diverse populations and ethnic groups in influencing the economic status of the metropolitan areas in the United States.
