Study: Undocumented Immigrants in US Reached Ten-Year Low
On Tuesday, the Pew Research Center reported that the number of immigrants staying in the United States without permission fell to a ten-year low in 2016. Researchers used government data to show that from 2007 to 2016, the number of undocumented immigrants dropped from 12.2 million to 10.7 million.
Pew linked the decrease to a large reduction in the number of Mexicans crossing the U.S. border illegally.
However, the number of immigrants from El Salvador, Guatemala and Honduras trying to cross over from Mexico illegally was up. Central America is the only region for which there was an increase in undocumented immigrants during the period of the study.
Arrests of Central Americans at the U.S.-Mexico border have also risen. But Pew researchers said arrests remained well below their highest number in 2014.
Most unauthorized immigrants overstayed their visas
Researchers found that two-thirds of adult unauthorized immigrants have lived in the U.S. for more than 10 years. Most unauthorized immigrants enter the U.S. on legal visas and remain after their visas reach the end of the period of stay they permit.
The latest overstay report showed that more than 700,000 holders of visas whose time limits had been reached should have left in the 2017 fiscal year. Pew said 90 percent of overstays were from countries other than Mexico or Central America.
Pew noted that forced expulsions – called deportations – of undocumented immigrants rose during the years when George W. Bush and Barack Obama were president. Deportations reached their highest point in 2013. These deportations could have affected the decrease in the undocumented population.
In the fiscal year 2016, most deportations were of people from Mexico, Guatemala, El Salvador and Honduras.
The report showed that based on limited data, deportations appear to have declined since then. It also shows a decline in those arrested at the U.S.-Mexico border, as well as an increase in those arrested inside the United States.

周二，皮尤研究中心报告称，2016年非法滞留美国的移民数量降至10年来的最低水平 。研究人员利用政府的数据显示，从2007年到2016年，非法移民数量从1220万下降到1070万 。
然而，试图从墨西哥非法越境的萨尔瓦多、危地马拉和洪都拉斯移民人数有所增加 。在这项研究期间，中美洲是唯一一个非法移民人数增加的地区 。
美国在美墨边境逮捕的中美洲人数量也有所上升 。但是皮尤研究中心的人员表示，逮捕人数仍远低于2014年的最高水平 。
研究人员发现，三分之二的成年非法移民在美国已经生活了10多年 。大多数非法移民持合法签证入境美国，并在签证到期后仍滞留美国 。
最新的逾期居留报告显示，逾70万签证到期的移民应该于2017财年离开美国 。皮尤研究中心表示，90%的签证逾期居民来自墨西哥或中美洲以外的国家 。
皮尤研究中心指出，在小布什和奥巴马执政期间，强制驱逐出境的非法移民人数有所上升 。被驱逐出境的移民数量在2013年达到顶峰 。驱逐出境可能影响到非法移民人数的下降 。
该报告显示，基于有限的数据，自那以后，被驱逐出境的人数似乎有所下降 。数据还显示，美墨边境被捕人数也有所下降，但美国境内被捕的移民人数却有所增加 。
