When a national ABS ranking and a NSW or Victorian registry list appear to disagree, the useful move is not to pick a winner but to work out what each list counted. This guide gives you a repeatable method: fix the comparison, match entries under the same rules, separate differences that have ordinary explanations from differences that do not, and put the specific question that settles the rest to each publisher.
Pin down what each list counted
Copy four things from each publication's own explanatory notes — the material that sits alongside the ranking table, not the table itself:
- Reference period — which year, or which range of years, the list covers.
- Scope — which population the counts are drawn from.
- Counting basis — what event placed a name in that period, and whether entries are added, corrected or removed after first release.
- Entry rules — whether alternate spellings appear as separate entries or as one grouped entry, and how any grouping is described.
You cannot reconcile two lists compiled under different rules; you can only describe the difference and decide which list answers your question. Treat everything in these notes as something to read at source: publishers update methodology between releases, and a rule you remember from an older edition may no longer apply.
A four-step reconciliation
Work in a spreadsheet or on paper; the order matters more than the tool.
- Freeze the inputs. Note the release date, the reference period and the address of each list you used. Re-download both if either has changed since your first comparison.
- Match spelling exactly first. Line up entries with identical spelling before you interpret near-misses. Two lists that group variants differently will not line up on a name-by-name pass until that rule is resolved.
- Record both positions, then the gap. For each name appearing on both lists, write both ranks side by side, plus any counts each publisher publishes. For names on one list only, note which list is missing them and whether that list's entry rules would have excluded them.
- Revisit only the rows with no explanation left. Everything else should already be accounted for by scope, timing or grouping rules.
Keep counts beside ranks wherever a publisher publishes them. A rank is only a position inside one list, so the same rank on two lists does not mean the same count, and a small rank gap can sit alongside a large difference in counts. Where counts are not published, record that as a limitation of the comparison rather than estimating.
A worksheet keeps the exercise honest:
| Name as printed | National rank | State rank | Same reference period? | Spelling matched? | Publisher's stated basis | Remaining gap |
|---|---|---|---|---|---|---|
| (your row) |
Fill the first five columns from the publications; leave the last empty for any row you can explain, which leaves a short, specific list to chase.
Differences that usually have an ordinary explanation
These are patterns worth checking first. They are practical interpretation, not claims about any particular release — confirm each one against the notes you copied above:
- Different populations. A national list draws on a far larger population than a single state list, so a name concentrated in one state can sit high locally and lower nationally, or the reverse.
- Different periods. The two publications may define their year differently, or may update counts after first release. An entry present in one list and absent from the other is often a timing question before it is a data question.
- Different spelling treatment. If one publication groups alternate spellings and the other lists them apart, ranks shift even when the underlying names are the same.
- Different coverage. Check exactly which jurisdictions and events each list includes before treating a missing row as a discrepancy.
If you can tick one of these boxes for a row, record the reason and move on. The goal is a short list of genuinely unexplained differences, not a longer list of guesses.
What the government name-recording guidance adds
The Attorney-General's Department publishes Recording of a name to establish identity—Better practice guidelines (publication date 10 August 2023). The department states that the guidelines aim to improve consistency and accuracy in the use of a name, particularly as an identifier by Australian Government agencies; provide best-practice guidance on establishing identity, including when changing a name and the use of a preferred name; and balance the operational requirements of different agencies while increasing consistency and uniformity in name policy and procedures.
How to read this in context: the guidelines describe how government agencies record and recognise a name, not how popularity rankings are compiled. Their practical value here is that two systems can hold different labels for the same person — a preferred name, or a name recorded after a change — so an apparent mismatch between lists can begin in how a name was recorded rather than in how it was counted. That is an interpretation of the guidance's scope; the guidance itself does not rank names or comment on registry statistics. The department's page also links to Australian Government Solicitor and ID Match material if you want the surrounding context.
When a difference is still unexplained
You have worked through the four steps, checked the ordinary explanations, and a name still sits differently on the two lists. At that point:
- Put both stated bases side by side and confirm they genuinely match — same period, same scope, same grouping rule.
- If they match, keep the difference as an open question rather than calling either list wrong.
- Ask each publisher precisely: the name, both ranks, both release dates, and the notes you read. Release notes and contact details sit on each publisher's own site.
Publishers revise figures and methodology, so a gap open today can close on the next release. Re-run the worksheet then.
Next steps
- Pick one reference year and one state list.
- Copy the four items from each publisher's notes into your worksheet header.
- Work through the four-step match, starting with exact spellings.
- Sort the remaining rows into "explained" and "open", and put only the open ones to the publishers.
