Illegal immigrant population of the United States

Illegal immigrant population of the United States
The actual size and the origin of the Illegal immigrant population in the United States is uncertain and hard to ascertain because of difficulty in accurately counting individuals in this population. National surveys, administrative data and other sources of information provide inaccurate measures of the size of the illegal immigrant population and current estimates based on this data indicate that the current population may range from 7 million to 20 million. An often used number in 2008 is 11 million. This is a decline from the historic peak of 12.5 million seen in 2007.[1] Critics claim this correction is in error-whatever size correction is used. Using the residual methodology with a minimal 10% foreign born undercount correction (reason for correction size unstated) for the 2000 Census and a 700,000 net illegal immigrant increase/year assumption and data from the March 2004 Current Population Survey [CPS Survey] (U.S. Census Bureau and Department of Labor) Pew estimated 10.3 million unauthorized immigrants in 2004. Assuming the same rate of growth Pew projected this population reached at least 11 million as of March 2005. The Pew Hispanic Center estimates that in the 1980’s the net advance of the undocumented population was at the 130,000 per year increasing to 450,000 per year from 1990-94, and further increasing to 750,000 per year from 1995-1999 and staying at 700-850,000+ per year since about 2000. Illegal Mexican immigration amounts to about 500,000 per year of this influx since about 1999. According to the same Pew Hispanic Center study as of March 2005, the undocumented population had reached 11 million or more including more than 6.5 million illegal Mexicans (~60% of all illegal immigrants). Assuming the same rate of growth as in recent years gives about 12,000,000 illegal immigrants in the United States as of January 2006, increasing at 700,000–850,000 per year with illegal Mexicans amounting to about 60%+ (7+ million) of the total by 2006. By September 2006 the illegal population is thought to be about 13 million. About onesixth of the undocumented population — about 2.0 million people — is under 18 years of age.[6]. After 2000 the estimation of the growth of the illegal population becomes more difficult because of a lack of good information. The rate of growth of the illegal population is estimated with the Consumer Price Survey data [2004] which suffers from the same under counting problems of the Census plus the problem of a much smaller statistical sample used of only 10,000–20,000. Its accuracy may

According to the Bureau of Transportation statistics [2] there are over 200,000,000 legal border crossings from Mexico each year, ~80% by automobile. The number of illegal immigrants emigrating [leaving] the U.S. is estimated at about 240,000 per year (~2% of illegal population)

Residual method
The “residual method” is widely used to estimate the illegal immigrant population, where the reported census number of self proclaimed foreign born people in the U.S. census is subtracted from the known number of legal immigrants to obtain the unauthorized immigrant (residual) population[4]. This methodology is used by the US Department of Homeland Security[5], the Pew Hispanic Center, the US Census Bureau and others. Since unauthorized immigrants have many reasons for not answering the census correctly and no penalties for answering the census incorrectly, a direct subtraction has a well known source of undercount error and has to be corrected. All known users of this methodology correct the foreign born population (~ 35-50 million) by 10-40% (3-12 million) to account for this undercount effect.

Impact of the global financial crisis of 2008–2009
The global financial crisis has had a large impact on America. The construction sector and other areas illegal immigrants traditionally seek employment in have shrunk. The recession has also led to a surplus of American labor driving down the benefit of hiring illegal immigrants. It is estimated that over a million illegal immigrants have returned to Mexico since the beginning of the crisis.[11]

According to a Pew Hispanic Center report, Mexicans make up 57 percent of the undocumented immigrants. Another 24 percent are from other Latin American countries. Approximately 9 percent are from Asia, 6 percent from Europe and Canada, with the remaining 4 percent from the rest of the world [5]. Country of Origin (January 2006) Mexico 6,840,000 57% Latin & Central Amer. 3,000,000 24% Asia 1,080,000 9% Europe + Canada 720,000 6% Rest of World 480,000 4% The number of Mexican legal immigrants and Mexican illegal aliens in the United States has grown quite rapidly over the past 35 years, increasing almost 15-fold from about 760,000 in the 1970 Census to more than 11 million in 2004—an average annual growth rate of more than 8 percent, maintained over more than 3 decades. This remarkable growth has been largely driven by the encroachment of illegal aliens. On average the net Mexican population living in the United States has grown by at least a half million people a year over the past decade. About 80 to 85 percent of the immigration from Mexico and Central America in recent years has been illegal. (Pew report Figure 4 and page 2)
