Washington • Border Patrol agents stationed in South Texas are the busiest in the country, arresting tens of thousands of children illegally crossing the border without their parents and thousands more families with children.
Here's a look at some numbers on the immigration situation.
—In the last budget year, Border Patrol agents arrested about 420,000 people, most of them along the Mexican border. That followed a three-year trend of near record low numbers of apprehensions.
—Overall, the number of immigrants caught sneaking across the border remains at near historic low levels.
—The last time so few people were arrested at the country's borders was 1973, when the Border Patrol recorded just fewer than 500,000 arrests.
