People, Growth of U.S. Population

The territories of the United States spread across many geographic regions and climates. The land stretches from the tropics to the edges of the Arctic. These varied terrains have attracted, challenged, and supported many different groups of people. America’s relatively low population density and its relatively high standard of living, along with opportunities for free expression, continue to fuel immigration to the United States. The nation remains a magnet for immigrants, despite the fact that substantial disparities exist in wealth and in access to resources between recent immigrants and more established Americans.
