What this page cannot show

  • An encounter is an event. The same person may be encountered more than once, so this is not a count of Mexico citizens.
  • Citizenship is what CBP recorded at the encounter. It is not a claim about where a person lived, travelled from, or was born.
  • CBP names a fixed set of countries and groups every other nationality as Other, so the countries published here are not the full range of nationalities encountered.
  • These counts describe enforcement activity. They do not measure migration from Mexico or the number of Mexico citizens in the United States.

Full method at methodology.
