Numbers display up to 6 decimal places. Nonzero values below 0.000001 use scientific notation. Calculations use the unrounded inputs.
Method and assumptions
- The check compares labels only; no count or casualty total is requested or subtracted.
- Labels are compared after Unicode, case and whitespace normalization; punctuation and substantive wording remain significant.
- A matching label is a review aid, not proof of identical underlying collection methods.
What this tool can tell you
- Missing fields remain unknown. Different dates, geography, attribution or verification methods must not be treated as equivalent.
- Even fully aligned entered fields do not establish that a numerical difference measures a real change.
