In 2007 there were around 12.2 million undocumented immigrants in the United States unlike in 1990 there were only 3.5 million. By 2016 unauthorized immigrants in the United States started to decrease to around 10.7 million, according to the Pew Research Center’s new report. The 2016 estimate was the lowest estimate of unauthorized immigrants in the United States in a decade.
The largest decreased in undocumented immigrants living in the US was from Mexico. In 2007, approximately 6,950,000 unauthorized Mexican immigrants were living in the US. But in 2016 the number decreased by 5,450,000. The Pew Research Center wrote an opinion piece in 2012 for CNN about the reasons why there was a decreased of unauthorized Mexican immigrants. According to Jeffrey S. Passel and D’Vera Cohn of Pew Research Center, they believed that many factors were at work, on both sides of the border including the US economy slow down, the law enforcement on the border, Mexico’s recession from 2008 to 2009 and there the decline in birth rates in Mexico.
Between the years 2012 and 2017 undocumented immigrants from El Salvador, Honduras, and Guatemala were in the top five countries to get a denied asylum applications. Of those who applied for asylum, between 75% and 79% of applicants were denied.
Even though there’s a decreased in unauthorized immigrants, the length of time they’ve spent in the US has increased. In 2016 the median number of years for adult staying in the US was 14.5 years unlike in 1995 was 7.1 years. In 2005 only 35% undocumented immigrants were living in the US and in 2016 two third of undocumented immigrants had been living in the US for more than 10 years.
The research conducted by Pew Research Center is based on data from the American Community Survey or the Current Population Survey which provides an estimated immigrant population. Pew Research Center uses the data adjusted for omissions from the survey.
