San Diego's border barrier 'almost completely ended illegal crossings.
In his State of the Union Address this week, President Donald Trump pointed to San Diego's border fence with Mexico as an example of where 'walls work and walls save lives.' 'San Diego used to have the most illegal border crossings in our country. In response, a strong security wall was put in place. This powerful barrier almost completely ended illegal crossings,' he claimed. Given the many arguments for and against Trump's border wall, we decided to fact-check the second part of the president's claim, that the San Diego barrier 'almost completely ended illegal crossings.' Was it the barrier that led to this dramatic change? Or did other factors help reduce illegal entries? We set out on a fact check. Our research The president is correct about the dramatic drop in illegal border crossings, which are measured by border patrol apprehensions. Those arrests in the San Diego sector plummeted 96 percent from nearly 630,000 in 1986 to 26,000 in 2017, according to the Associated Press. The biggest drop took place in the late 1990s, several years after San Diego's first border fence was built. But illegal entries across the entire Southern border, and not just in San Diego, have been on the decline for nearly two decades. They've dropped from more than 1.5 million in 2000 to less than 500,000 in 2018, according to the The New York Times. Based on these news reports, plus interviews with experts on the border and a 2007 Congressional Research Service report, PolitiFact California found that San Diego's fencing was not the only reason for the dramatic decrease in illegal crossings. 'It's not only the fence,' said Victor Clark-Alfaro, a Latin American Studies professor at San Diego State University. 'It has to do with (expanded) job opportunities in Mexico, it has to do with rhetoric from Trump.' The federal government 'also increased technology and staffing,' added Paola Avila, vice president of international business affairs at the San Diego Regional Chamber of Commerce. 'You need to see the whole picture.' The White House did not respond when asked about Trump's statement. Doubling of border patrol agents The Congressional Research Service is Congress' nonpartisan public policy research arm. The research group's 2007 report found migrants successfully bypassed, or in some cases went through, San Diego's initial, primary fence in the early 1990s. That led to the construction of a triple-layer fence plus a more-than doubling of border patrol agents and an increase in technology used to stop the illegal entries. 'Although much of this reduction in apprehensions in those stations and in San Diego sector may have been due to the construction of the triple-fence,' the report said, 'the sector also saw an increase in other resources that may account for part of the reduction. For example, the number of agents assigned to the San Diego sector increased significantly during this period - from 980 agents in 1993 to 2,274 in 1998. Additionally, the number of underground sensors deployed in the San Diego sector almost tripled from 1993 to 1998, and the fleet of vehicles increased by over 150% over the same period.' David Shirk, professor of political science and international relations at the University of San Diego, said in an email that the added physical barriers in San Diego helped reduce illegal crossings. But the rapid increase in border agents also played a key role, Shirk said, by diverting 'migrants to other crossing points east of San Diego, in much more dangerous mountain and desert areas, causing thousands of people to die due to exposure to the elements over the last 25 years.' Avila, of the San Diego regional chamber, cited one more piece of the border picture: Tunnels. She said dozens of completed tunnels have been discovered under the San Diego border in recent decades, potentially skewing the number of illegal crossings and the notion that fencing alone prevents unauthorized migration. Our rating President Trump claimed San Diego's border fence 'almost completely ended illegal crossings.' He's right that border patrol arrests have plunged, declining 96 percent along the San Diego sector, from 1986 to 2017. The biggest drop took place in the late 1990s, after a triple-layer barrier replaced an initial fence built in 1993. But experts on the border, along with a congressional report, show San Diego's border fence was only one factor in helping reduce the crossings. A surge of border patrol agents, vehicles and technology along with improved economic opportunities in Mexico all played important roles. Trump's statement ignores these key factors, giving credit only to the barrier. We rate his claim Half True.
