Fence systems work so well that illegal crossing arrests are down 82% from around 15 or 17 years ago, peak high.
From peak highs, San Diego - down 92%, El Paso - down 95% Tucson - down 92% Yuma, AZ - down 96%.
It pushes those attempts further away from population centers. Also why thousands more have died, and these are just the ones where some of the bodies have been recovered. So effective that advocacy groups in the past call border patrol murders and junk like that. People can barely carry enough water to survive.

"It was an area that was out of control," Henry says. "There were over 100,000 aliens crossing through this area a year."
Today, Henry is assistant chief of the Border Patrol's San Diego sector. He says apprehensions here are down 95 percent, from 100,000 a year to 5,000 a year, largely because the single strand of cable marking the border was replaced by double -- and in some places, triple -- fencing.
"Coffins" with the word "deaths" written on them in Spanish hang along the Mexican side of the border fence. Activists say the wall has forced immigrants to take life-risking routes through the desert to cross into the United States.

More agents and stricter enforcement policies intentionally funnel migrants into the most inhospitable stretches of eastern Arizona and western Texas, where the terrain is the hardest and hottest. A study published last year by the University of Arizona showed that the funnel effect had turned Tucson into “the single most traversed crossing corridor for migrants along the entire U.S.-Mexico border.”

Some 5,600 people have died trying to cross into the United States since the U.S. government under President Bill Clinton dramatically increased border security in 1994 with Operation Gatekeeper and the first stretch of fence between San Diego and Tijuana.
Before the stepped-up enforcement operations, experts say most deaths were due to traffic accidents as migrants dashed across freeways in border areas. Today, most die from hypothermia in the desert or by drowning in the Rio Grande and irrigation canals.

attributable in large part to the increased militarization of the border and an intermittent fence that diverts migrants through treacherous desert terrain. From 1990 to 2000, the average number of migrant deaths each year was 12, but since 2000, that number has increased to 167 (Pima County Office of the Medical Examiner). Since 1998, more than 6,500 have died along the U.S.–Mexico border (U.S. Border Patrol).
