The right answer is: Urbanization. Urbanization is the result of the spatial interaction, mainly of vital revolutions and mobility. It is characterized by different levels of urban mortality - rural differentials in fertility - and the pattern of descent , in addition to the massive net transfer of the population from the urban areas through internal migration, thus generating a process of urbanization that all nations go through in the course of their transition from an agricultural society to an industrial one.
The correct term is urbanization. As immigration increases, immigrants are concentrated in cities, looking for work. More people means more available labor, which means that industrialization is more likely to take place. Factories develop, and this leads to urbanization and the growth of cities. As cities get larger, immigrants are more likely to believe jobs are available, which leads to increased immigration, perpetuating the cycle.
The Declaration of Independence claims that if the government becomes destructive and/or toxic the people have the right and duty to "alter or abolish it and to institute new Government". This means that the people have the right to overthrow the government and change it if they feel as if the government is doing more harm than good.
