More than a quarter of a million people illegally present in the United States were removed from the country in fiscal year 2018, according to U.S. Immigration and Customs Enforcement.

Approximately half of the 158,000 people arrested by ICE — 80,730 — had been charged or convicted of driving under the influence, according to the agency's annual report.

The second-highest category for arrests was for crimes related to "dangerous drugs," followed by traffic offenses.

Immigration offenses — like having been deported once before — was a common denominator for more than 63,000 of the people arrested.

More than 50,000 people taken into custody had been charged or convicted on assault.

Exactly 23,052 people had faced legal trouble for obstructing judiciary, Congress, legislature, etc.

The criminal backgrounds are the reasons they were known to law enforcement and pursued by ICE.

More than half of the total 256,085 people who were removed from the country were Mexican citizens, making it the country with the most nationals deported from the U.S.

A little more than 141,000 Mexicans were removed. Mexico, part of North America, was followed by the three northernmost countries in Central America: Guatemala, Honduras, and El Salvador, respectively.

Guatemala had approximately 50,000 citizens repatriated. Honduras received 28,894 citizens and El Salvador, 15,445.

The Dominican Republican, Brazil, Ecuador, and Colombia were next, with between 1,100 and 1,800 repatriated citizens each.

China and India were also among the countries with the most citizens returned, though nowhere near the rates of the top countries. Both nations had 726 and 611 citizens repatriated, respectively.
