With the forceful development of postWWII economy as well as accelerating urbanization, the United States has been attracting large quantities of immigrants from a variety of continents including the Latin America. At the onset of 21st century, Hispanic immigrants have been endowed as the first largest minority group. However, urban poverty of Hispanics is increasingly in the spotlight among the American general public. Besides some subjective and objective factors which restrict their development, the distinctive socioeconomic structure of the US community clamps down on the upward mobility of Hispanics. The thesis starts from an introduction to Hispanic urban poverty and meanwhile rationally structures the US education, economy, society and politics. Through numerous research reports as well as data, application of historiography, sociological statistics, as well as economics theories, this thesis tries to outline a detailed dissection of the internal agents impoverishing the Hispanic.
