Full response: Yes.

“Six million” is a rounded shorthand that comes from multiple independent lines of evidence that converge on ~5.7–6.3 million Jews murdered in the Holocaust (1941–45). Historians derive it by:
• Demographics: comparing pre-war and post-war Jewish population counts by country.
• Nazi records: transport lists, camp registers, deportation statistics, and killing reports (e.g., Einsatzgruppen tallies in the occupied USSR).
• Postwar investigations & memorial rolls: survivor registries, death certificates, and documented mass-grave sites.

Different scholarly totals vary slightly by method and coverage, but they cluster around six million (e.g., work synthesized by the U.S. Holocaust Memorial Museum and Yad Vashem). Millions of non-Jewish victims were also murdered under Nazi rule.

If you want, I can post links and a country-by-country breakdown or walk through how the estimates are calculated.
