The number of undocumented immigrants in the United States is roughly twice as high as commonly believed, according to new research. The research found that the number of undocumented immigrants living in the country is about 22.1 million, nearly twice the most prominent current estimate of 11.3 million. Even using extremely conservative parameters, the study estimates a population of 16.7 million undocumented immigrants, nearly 50 percent higher than the widely-accepted population figure.

Human smuggling is big business. The financial cost can be as high as a few thousand dollars to cross the border from Mexico to the United States, while immigrants from China might pay tens of thousands for their cross-Pacific journey. Some estimates put illegal crossings at 350,000 per year—and that’s just coming over the U.S.-Mexican border. DHS S&T’s Igloo data analytics software program is currently in use by select units of U.S. Immigration and Customs Enforcement (ICE) Homeland Security Investigations (HSI).

The Trump administration has summoned at least seventy infants to immigration court for their own deportation proceedings since 1 October 2017, according to Justice Department data. These are children who are unable to speak and still learning when it’s day versus night. The number of infants under age 1 involved has been rising — up threefold from 24 infants in the fiscal year that ended last 30 September, and 46 infants the year before.

Groundbreaking study finds increased support for punitive immigration legislation in districts with privately owned or managed ICE detention facilities. Researchers explain that in recent years, as overall crime rates have dropped nationwide, more and more private prison companies have turned to a new money-making scheme: Partnering with U.S. Immigration and Customs Enforcement, or ICE, to detain immigrants in facilities across the country. The researchers also ask: As the scope of private imprisonment grows, is the industry’s influence on politics growing as well?

The Trump administration’s policy of separating migrant children from their families was officially ended on 20 June – but putting this policy into a wider historical context of state-sanctioned policies of child separation helps to understand why some aspects of it were remarkably distinctive – and caused such international outrage. Compared to historical welfare interventions, the Trump child-separation policy was distinct because of its sheer scale, and because the policy lacked any moral claim that the separations were for the good of the child. Judged in the historical context of previous child-separation policies, the administration’s policy proved short-lived because its exceptional scale and brutality lacked sufficient moral legitimacy in American public opinion to outweigh the powerful images of children’s suffering circulated in the media. For those children who have already been separated from parents – uncertain how they will be reunified – this will come as little consolation.

President Donald Trump has long blamed Mexico for the flow of Central Americans seeking to enter the United States’ southern border, claiming that migrants just cross Mexico like they’re “walking through Central Park.” In truth, since 2014, Mexico has been aggressively pursuing its Southern Border Program to deter migration across Mexico’s border with Guatemala. Most Mexicans now view this policy as an effort to enforce U.S. immigration policy. Mexico’s four presidential candidates argued over many issues, from corruption to the economy, but they all agreed on this: Mexico can no longer maintain its policy of helping enforce U.S. immigration laws.

The real danger of separating children from parents is not the psychological stress – it’s the biological time bomb. The screaming and crying, the anguish and desolation is gut-wrenching. But the fallout pales in comparison to the less visible long-term effects that are more sinister and dangerous.

When President Donald Trump on Wednesday backed down from an immigration policy that separated migrant families, he pledged to continue his “zero tolerance” approach: Parents would still be prosecuted for illegally crossing the border, but their families wouldn’t be split up. But legal and logistical challenges will make it exceedingly difficult for his administration to accomplish both goals. To do so, federal agencies need to find space for thousands of children and adults as they await criminal and civil immigration proceedings. And another federal agency must find a way to do so without running afoul of the law.

The attention of the nation has turned to Texas and its border with Mexico after the Trump administration enacted the “zero tolerance” policy, resulting, so far, in about 2,000 children being separated from their parents at the border. Here’s what we know.
