Population Change Foreign-born Americans and their descendants have been the main driver of U. They also will be the central force in U. If no immigrants had entered the country afterwhen the U.
In this report, we refer to either foreign-born persons or immigrants, unless we wish to distinguish a particular type of immigrant.
Impact of Immigration on the U. Population What influence will immigration have on the size and composition of the U. To answer that question, the panel developed a demographic model that projected the population to the year This model projects an initial population under various assumptions about fertility, mortality, and international migration.
It places special emphasis on understanding the effects of immigration on the total population, its age structure, the size of the foreign-born population, and the ethnicity of its descendants. The model adds a generational perspective to demographic projection by distinguishing immigrants and their descendants, along with the current native-born population, using data on fertility, mortality, exogamy rates of intermarriageand ethnic affiliation that vary by generation and ethnicity.
In our projections, we used five alternative assumptions about the numbers of immigrants in the coming decades: If net immigration continues indefinitely at its current levels, there will be million people in the United States inmillion more than at present.
Immigration will play the dominant role in that growth, accounting for 80 million, or two-thirds, of the increase. Even if net immigration were halved, toa year, the population would still rise to million.
And if it were increased by half, to 1, a year, the population would be million by the middle of the 21st century. Immigration will also affect the age distribution of the resident population, with crucial implications for public policy.
Under current immigration policy, enrollment in kindergarten through grade eight will increase to If immigration were cut in half, that number would be High school enrollments will rise from With a low immigration assumption, the absolute size of the population aged 65 and over will be Economic, Demographic, and Fiscal Effects of Immigration.
The National Academies Press. The proportion of older people in the total population will be smaller with higher immigration, however: Our demographic model also projects the racial and ethnic composition of the future population, divided into four mutually exclusive groups: Under any immigration scenario, both the absolute and the relative sizes of the Asian-ancestry and Hispanic ancestry populations will grow rapidly.
Assuming continued net immigration at current levels, the size of the Asian population will increase from 9 to 34 million in growing from 3 to 8 percent of the population.
This growth stems mainly from the large fraction of Asians in the immigrant population. Similarly, fueled by higher fertility, high rates of immigration, and high affiliation rates, the Hispanic population will grow substantially over this period.
Assuming continued net immigration at current levels, and current rates of intermarriage and ethnic affiliation, the Hispanic population will rise from 27 million in about 1 in 11 of the population to 95 million in about 1 in 4 of the population. These projections incorporate the assumption that current levels of intermarriage will continue, and thus that the proportion of people with multiple-ancestry will increase.
Multiple-ancestry adds complexity and ambiguity to ethnic definitions, and it is possible that, by the middle of the next century, ethnic and racial lines will be even more blurred.
Economic Impacts of Immigration The second charge to the panel concerned the impact of immigration on the U. Economic theory points to possible effects on the employment and wages of domestic workers, U.
To address these issues, the panel relied both on theoretical insights on what the likely effects would be, and on empirical estimates of the magnitude of the actual effects.
Using a basic economic model, with plausible assumptions, we show that immigration produces net economic gains for domestic residents, for several reasons. At the most basic level, immigrants increase the supply of labor and help produce new goods and services.
But since they are paid less than the total value of these new goods and services, domestic workers as a group must gain. Page 5 Share Cite Suggested Citation: On the production side, immigration allows domestic workers to be used more productively, specializing in producing goods at which they are relatively more efficient.
Specialization in consumption also yields a gain. Immigration thus breaks the rigid link between domestic consumption and domestic production. From this perspective, the effects of immigration are comparable to those of international trade.
That the two processes are so similar suggests that, when trade is relatively free, any change in the number of immigrants will affect the incomes of domestic workers less than it would have without trade.
In our baseline analysis, we assume that the U. Existing research has not convincingly demonstrated that, in the aggregate, either decreasing returns due to fixed factors or congestion effects, or increasing returns, are more compelling alternatives. We caution, however, that we would not extrapolate far beyond current levels and say that immigration flows much larger that those considered in our demographic projections would always produce economic gains.
With far larger flows, and over long periods of time, the uncertainty about increasing or decreasing returns to scale would have to be resolved with sound empirical evidence."That's one key recommendation that emerged in September from the Independent Task Force on Immigration and America's Future.
Its report, prepared by the Migration Policy Institute, is the most thoughtful analysis yet completed on immigration. The world has gone through a revolution and it has changed a lot. We have cut the death rates around the world with modern medicine and new farming methods.

Although the United States has long relied on immigration to fuel productivity, maintain a competitive edge, and drive the dynamism that characterizes American society, the nation’s overburdened immigration system—the breakdown of which has manifested in an alarmingly large unauthorized population—is no longer serving America’s needs.
Throughout its history, the United States has been a nation of immigrants. The door may not always have been wide open, but it has never been completely shut.
