Study: Undocumented Immigrants in US Reached Ten-Year Low

研究稱美國非法移民數(shù)量降至十年最低點

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.

周二，皮尤研究中心報告稱，2016年非法滯留美國的移民人數(shù)下降到了10年的最低點。研究人員采用的政府?dāng)?shù)據(jù)顯示，從2007年到2016年，非法移民人數(shù)從1220萬下降到了1070萬。

Pew linked the decrease to a large reduction in the number of Mexicans crossing the U.S. border illegally.

皮尤研究中心將這種下降與墨西哥人非法越境數(shù)量大幅下降聯(lián)系了起來。

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.

然而，試圖從墨西哥非法越境的薩爾瓦多、危地馬拉和洪都拉斯移民人數(shù)有所上升。在這項研究期間，中美洲是唯一一個非法移民人數(shù)增加的地區(qū)。

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.

中美洲人在美墨邊境被逮捕的數(shù)量也有所上升。但是皮尤研究中心的研究人員表示，逮捕人數(shù)還是遠遠低于2014年的最高點。

Most unauthorized immigrants overstayed their visas

大多數(shù)非法移民簽證到期后逾期居留

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.

研究人員發(fā)現(xiàn)，三分之二的成年非法移民已經(jīng)在美國生活了十多年。大多數(shù)非法移民通過合法簽證進入美國，并且在簽證允許停留期到期后繼續(xù)留在美國。

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.

最新的逾期居留報告顯示，2017財年，有超過70萬簽證已到期的人員應(yīng)該離開美國。皮尤研究中心表示，90%的簽證逾期居留者都來自墨西哥或中美洲國家。

Deportations

驅(qū)逐非法移民

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.

皮尤研究中心指出，在小布什和奧巴馬擔(dān)任總統(tǒng)期間，強制驅(qū)逐出境的無證移民人數(shù)有所上升。驅(qū)逐出境人數(shù)在2013年達到了最高點。驅(qū)逐出境可能影響到了無證移民的下降。

In the fiscal year 2016, most deportations were of people from Mexico, Guatemala, El Salvador and Honduras.

在2016財年，大多數(shù)人驅(qū)逐出境者都來自墨西哥、危地馬拉、薩爾瓦多和洪都拉斯。

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.

該報告顯示，基于有限的數(shù)據(jù)，驅(qū)逐出境人數(shù)似乎從那時起就開始下降。數(shù)據(jù)還顯示，美墨邊境被逮捕的人數(shù)也有所下降，而在美國境內(nèi)被逮捕的人數(shù)有所增加。
