There are roughly 1.5 million U.S. residents born in the UK based on recent census-style estimates and long-running migration patterns, though the exact figure depends on whether you count only UK-born people or also UK nationals and descendants.

What that means

  • The most direct way to read the question is: people living in the U.S. who were born in the United Kingdom.
  • That group is commonly estimated in the low millions , not just thousands.
  • The number can vary by source because the U.S. does not publish a single always-current count for this exact group in the same way every year.

Why the number varies

  • Some datasets count place of birth.
  • Others count nationality , which is different.
  • Some sources also split the UK into England, Scotland, Wales, and Northern Ireland, which changes totals depending on how they’re combined.

Practical answer

If you want a simple headline number, about 1.5 million is a reasonable estimate for UK-born people living in the U.S.

TL;DR

  • Estimated UK-born residents in the U.S.: about 1.5 million
  • The exact total depends on the source and definition used.
