National Academy of Sciences Report Indicates Amnesty for Unlawful Immigrants Would Cost Trillions of Dollars
National Academy of Sciences on the Fiscal Cost of Immigrants
In September 2016, the National Academy of Sciences (NAS) released a major report, The Economic and Fiscal Consequences of Immigration, analyzing the fiscal balance (total government benefits received, minus total taxes paid) for immigrants with different levels of education. In particular, the report provides 75-year fiscal projections for the fiscal balance of immigrants and their descendants based on the immigrant’s education level. Since the education level of current illegal immigrants is generally known, the NAS fiscal balance projections can be used to estimate the fiscal cost of current illegal immigrants after an amnesty.
The NAS report does not distinguish between legal and illegal immigrants, but since it does provide fiscal projections at different education levels, and because the education level of current adult illegal immigrants is approximately known, the NAS projections enable us to project the fiscal costs of illegal immigrants if they were granted amnesty or earned citizenship as a group.
The study clearly shows that the net fiscal impact (benefits received minus taxes paid) of immigrants varies greatly according to their education level. According to the NAS research, each immigrant without a high school diploma would impose an average long-term net fiscal cost of over $650,000 on taxpayers. Thus, the education level of illegal immigrants has a large impact on the fiscal cost of amnesty.
Education Level of Illegal Immigrants
There are currently around 10 million adult illegal immigrants in the U.S. with an average age of 35. Chart 1 compares the education levels of illegal immigrant adults to legal immigrants and non-immigrants. As a group, illegal immigrants are poorly educated; nearly half do not have a high school diploma, and only 11 percent have a college degree. Adult illegal immigrants are six times more likely to lack a high school diploma than are U.S.-born residents.
Illegal immigrants currently benefit from routine government services such as roads, sewers, police, and fire protection. The children of illegal immigrants currently receive heavily subsidized public education at an average cost of $12,000 per child per year. Children of illegal immigrants born in the U.S. are eligible for the same welfare benefits (such as food stamps, Medicaid, Obamacare, and Temporary Assistance for Needy Families) that children born to U.S. citizens are eligible to receive. Because illegal immigrant families already receive many government benefits and services, they currently impose a fiscal cost on taxpayers: The benefits they receive exceed the taxes paid.
Amnesty or earned citizenship would provide current illegal immigrants access to an additional level of expensive government entitlements and benefits. All of the major comprehensive immigration reform or earned citizenship bills debated in Congress since 2006 would have granted nearly all current illegal immigrants eligibility for future Social Security and Medicare benefits after 10 years of work. These bills also would have provided amnesty recipients access to almost the entire U.S. welfare system after modest delays. It is true that after amnesty, former illegal immigrants would be more likely to work “on the books” and therefore would pay somewhat more in taxes. However, the increase in tax payments would be dwarfed by the cost of added entitlements.
In effect, amnesty would give current illegal immigrants access to the same government benefits as those for which current legal immigrants are eligible. Thus, as a general rule of thumb, the long-term fiscal balance of an illegal immigrant after amnesty would be roughly equal to the cost of a current legal immigrant with the same age and education level.
In general, less-educated individuals, whether they are illegal immigrants, legal immigrants, or non-immigrants, receive far more in government benefits than they pay in taxes. For example, a household headed by a legal immigrant without a high school degree typically receives about $4.00 in benefits for every $1.00 of taxes paid. Because illegal immigrants tend to have low levels of education, granting them access to Social Security, Medicare, Obamacare, and means-tested welfare would lead to substantial long-term costs for taxpayers.
Table 1 applies the NAS projected 75-year fiscal balances for immigrants by education level to the current adult illegal immigrant population. This provides an estimate of the aggregate fiscal cost of illegal immigrants subsequent to a grant of amnesty or earned citizenship. The NAS projected fiscal estimates for immigrants include federal and state benefits that would be received, minus all taxes to be paid, for both the first and second generation of immigrants.
Net Present Value of Future Costs
Based on the education level of illegal immigrants, the NAS figures project that the net fiscal cost (benefits minus taxes) for 10 million adult illegal immigrants after receiving amnesty would have a net present value of negative $1.29 trillion. The concept of “net present value” is complex; it places a much lower value on future expenditures than on current expenditures.
One way to explain net present value is that it represents the total amount of money that would have to be raised today and put in a bank account earning 3 percent interest above the inflation rate in order to cover future costs. This means that if amnesty were enacted, the government would have to raise taxes immediately by $1.29 trillion and put that sum into a high-yield bank account to cover the future fiscal losses that would result from the net fiscal costs of amnesty recipients and their children.
The $1.29 trillion figure equals $15,300 for each U.S. household currently paying federal income tax. To cover the future cost of illegal immigrants after amnesty, each taxpaying U.S. household, on average, would have to pay an immediate lump sum of over $15,000.
Of course, if the federal government were to grant amnesty, it would not actually raise current taxes by $1.29 trillion and put the money in a high-yield bank to cover the future costs. Instead, in the government’s normal pattern, the costs would be unfunded and passed on to future years’ taxpayers. Converting a net present value figure into future outlays requires information on the exact distribution of costs over time; unfortunately, such data are not provided by the NAS. However, a very rough estimate of the future net outlays to be paid by taxpayers (in constant 2012 dollars) for illegal immigrants after amnesty is around $3.6 trillion over 75 years. The average long-term fiscal loss per adult illegal immigrant (in constant 2012 dollars) would be around $360,000.
Additional Factors that Influence Costs
There are several factors that could raise or lower this estimate of projected costs.
Number of Illegal Immigrants. Most sources estimate that there are around 11.4 million illegal immigrants of all ages in the U.S. Some 90 percent of these individuals are estimated to appear in the government’s annual census surveys; another 1.1 million are assumed to reside in the U.S. but remain unreported in surveys. In reality, the number of illegal immigrants who are present in the country but not recorded in census surveys is largely unknown and could be much higher than 1.1 million. A higher number of illegal immigrants would raise amnesty costs.
Number of Amnesty Recipients. Earned citizenship bills typically would permit nearly all illegal immigrants residing in the U.S. at the time of enactment to apply for and receive legalization. The fiscal projections in Table 2 assume that all of the 10 million adult illegal immigrants currently residing in the U.S. would apply for and receive legalization. In reality, some would not apply. However, there is also likely to be widespread cheating in any amnesty. In the 1986 amnesty, an estimated 25 percent of the amnesties granted were fraudulent. In the past 20 years, the underground industry producing fraudulent documents has grown vastly larger and more sophisticated. In any future amnesty, the fraud rate could be as high as or higher than in 1986, resulting in more than 10 million amnestied adults. If cheating increased the number of amnesty recipients by 25 percent, the added lifetime fiscal cost would be around one-quarter higher.
Re-emigration. Future costs will be affected by the number of immigrants who re-emigrate to their country of origin. The NAS estimates used in Table 2 assume a very high re-emigration rate of 29 percent. It is unlikely that 29 percent of amnesty recipients would actually re-emigrate. The NAS also reports that the emigration rate for immigrants who have been in the U.S. for over 10 years is only 7 percent; this seems a more reasonable emigration figure for future amnesty recipients. A lower re-emigration rate could raise the estimated cost of amnesty by a third.
Understated Costs of Legalization. The NAS fiscal projections are for all immigrants by education level; the report does not distinguish between legal and illegal immigrants. Because illegal immigrants are currently ineligible for Social Security, Medicare, means-tested welfare, and Obamacare, the current pre-amnesty fiscal cost of illegal immigrants is markedly lower than the cost for legal immigrants with the same education level. Hence, the NAS per-immigrant cost projections in Table 2, which combine the higher costs of legal immigrants with the lower pre-amnesty costs of illegal immigrants, underestimate the actual cost of legalized immigrants by perhaps 20 percent. This would lead to an underestimate of post-legalization costs by a similar amount.
Education Levels of Illegal Immigrants. Estimates of the education level of illegal immigrants vary. For example, the Center for Immigration Studies (CIS) estimates th
at 53 percent of adult illegal immigrants lack a high school degree and that 9 percent have graduated from college. The Migration Policy Institute estimates that half of illegal immigrant adults lack a high school diploma. By contrast, the Pew Hispanic Center has estimated that some 42 percent of adult illegal immigrants lack a high school degree and that 16 percent are college graduates. Using the CIS figures would raise the net present value of the cost of amnesty in Table 2 by 10 percent. By contrast, the Pew figures would reduce projected amnesty costs by 20 percent.
Increasing Future Illegal Immigration. The U.S. enacted a small-scale amnesty for illegal immigrants in 1986. The public was promised that the 1986 amnesty was a one-time decision that would never be repeated. Despite this promise, the 1986 amnesty was probably a factor in encouraging the subsequent surge in illegal immigration, because it signaled that the U.S. might take a lenient stance toward illegal immigrants in the future. Enacting a second amnesty would establish a very strong precedent for serial amnesties. The prospect of recurring amnesties would certainly make future illegal immigration more attractive, drawing more illegal immigrants into the country and significantly increasing long-term fiscal costs.
Public Goods. Public goods are government services that do not need to expand as the population of the nation increases. Chief among these are national defense, interest on government debt, and scientific research. Because illegal immigration does not increase these costs, at least in the first generation, they have not been included in the NAS cost estimates used in this paper.
Consumer Costs. Low-skill illegal immigrant workers may push down wages and thereby reduce consumer costs. However, the NAS report indicates that the consumer gains from low-skill immigration are modest, and if the wages of less-educated immigrants are driven down, the wages of less-educated U.S. workers will fall as well. Any consumer gains would come at the cost of wage losses for the most vulnerable American workers.
Dynamic Externalities. Advocates of ongoing, massive low-skill immigration have suggested that low-skill immigrants (whether legal or illegal) generate large-scale economic externalities that benefit U.S. workers. The NAS report finds no evidence of such effects. The continuing inflow of low-skill immigrants into the U.S. creates large fiscal burdens for U.S. taxpayers in both the present and the future.
Earned citizenship bills typically would require illegal immigrants to pay a small fine before being put on the pathway to citizenship. For example, the “Gang of Eight” bill (S. 774) in 2013 would have charged each illegal immigrant a fine of $1,000. In exchange for paying this fine, the illegal immigrant would have been given access to Obamacare, Social Security, Medicare, and over 90 different means-tested welfare benefit programs, as well as the right to vote in U.S. elections. The net fiscal cost of amnesty recipients would clearly be hundreds of times greater than any fine they would pay.
In effect, earned citizenship bills “fine” U.S. taxpayers to pay extensive benefits to former illegal immigrants. Under such proposals, the illegal immigrant’s “right” to lay claim to these taxpayer funds results from their violation of U.S. immigration law in the first place. In the end, amnesty or earned citizenship would greatly reward individuals for breaking U.S. laws, impose enormous costs on U.S. taxpayers, and encourage increased new waves of illegal immigration.
