Important Caveats

  1. B0114 confusion: The 2011 yearbook's B0114 table uses 2000 data, not 2010. Don't accidentally compare 2000 vs 2020.
  2. 2020 table scope: C25-19 is labeled "ethnic autonomous regions" but ethnic group populations match national totals.
  3. Military/temporary populations: 2020 C02-21 total (1,409,778,724) differs from Census Bulletin #2 (1,443,497,378). Yearbook likely excludes certain populations.

Conclusion

All required data for a clean 2010 vs 2020 ethnic census comparison is present. The 2010_ethnic_minorities_distribution.md and 2020/C25-19_transcribed.md provide directly comparable individual ethnic population figures for all 55 groups.
