While the Census Bureau's press release accompanying its new population projections emphasizes the importance of the country's changing racial composition, this is almost certainly not the most important finding. The new report shows a U.S. population in 2050 that is 135 million larger than it is today. This could have profound implications for the environment and quality of life in the United States in the future. Immigration policy is the primary factor driving population growth.

The Center for Immigration Studies makes these observations on the new projections:

- A U.S. population of 439 million in 2050 is by far the largest ever projected by the Census Bureau. As recently as 1996, the Bureau projected a population in 2050 considerably smaller than is now projecting.

- The increase in the size of the overall U.S. population of 135 million between today and 2050 is larger than the combined populations of
Great Britain and France.

- Assuming the same ratio of population to infrastructure that exists today:

- The nation will need to build and pay for 36,000 more schools.

- Develop enough land to accommodate 52 million new housing units.

- Construct enough new roads to handle 106 million more passenger vehicles.

- Although the projections do not provide enough information to precisely determine the share of population increase due to immigration, prior research and some information in the study itself indicate that about three-fourths of this future population growth is driven by new immigration and births to immigrants.

- One of the more interesting findings in the Census Bureau projections is that even with record levels of immigration over the next 42 years, the population of the United States will still age significantly. This is consistent with prior research showing that immigration has only a modest impact on slowing the aging of American society.

Discussion: Adding 135 million more people to the nation's population is very likely to have significant implications for many things Americans care about, such as pollution, congestion, sprawl, and preservation of open spaces. It may also have implications for the size and scope of government as more densely settled societies are almost always more heavily regulated.

The new projections point to a policy choice. The United States may well decide to continue to allow the settlement of 1.5 million new
immigrants (legal and illegal) each year. But legal immigration is a federal program like any other and could be reduced below the 1 million currently allowed to legally enter the country each year. Greater resources could also be devoted to reducing illegal immigration. The projections provide a glimpse into one possible future. We must decide as a country if this is the future we want.
