If you want to track how Australian boy names have risen or fallen in popularity by year, the ozbabynames dataset is the open compilation that makes this possible. The ozbabynames package provides a dataset of popular Australian baby names by sex, state and year, drawing on state registry records (ozbabynames). You can filter to male names, pick a year, and see registration counts for individual states. The practical catch is that coverage is uneven: some states supply only recent years, some supply only the top 50 or 100 names, and the ACT is absent entirely because it does not provide counts (ozbabynames). Tracking a true national trend means understanding those gaps before you read a line chart.
What the ozbabynames dataset actually contains
The ozbabynames package contains the dataset ozbabynames, which lists popular Australian baby names by sex, state and year (ozbabynames). Each record pairs a name with a sex label, a state, a year, and a count of registered births. For a reader searching "Australian boy names by year popularity", this means you can interrogate the data with three filters: sex = male, a name string, and a year range.
The source page lists contributing registries: South Australia, New South Wales, Tasmania, Victoria, Western Australia, Queensland and the Northern Territory (ozbabynames). The ACT is explicitly excluded because it does not provide counts, so no ACT data appear (ozbabynames). The documentation demonstrates the dataset's function by filtering to 1952 and producing the top ten male and female names for that year (ozbabynames). That example confirms the data reach back at least to the early 1950s for some states, but it does not publish the names themselves in the source text we rely on, nor does it explain cultural reasons for any shift.
Where the historical coverage is strongest and weakest
Any rise-or-fall story depends on consistent reporting. The dataset's own Known Issues section states: "The coverage is very uneven, with some states only providing very recent data, and some states only providing the top 50 or 100 names" (ozbabynames). This is a factual limit you must carry into every trend line.
South Australia has by far the best data, with full coverage of all names back to 1944 (ozbabynames). If your question is how a boy name moved across the post-war period to today, South Australian counts give the longest continuous series in the package.
Tasmania applies a tighter rule: only top 10 by rank are available after 2016 (ozbabynames). For earlier Tasmanian years broader coverage may exist, but you should verify the exact scope on the linked state source before drawing a conclusion.
The table below records what the source explicitly confirms.
| State / Territory | Coverage note from ozbabynames |
|---|---|
| South Australia | Full coverage of all names back to 1944 |
| Tasmania | Only top 10 by rank available after 2016 |
| Australian Capital Territory | No data (does not provide counts) |
| New South Wales | Source listed; general uneven-coverage caution applies |
| Victoria | Source listed; general uneven-coverage caution applies |
| Western Australia | Source listed; general uneven-coverage caution applies |
| Queensland | Source listed; general uneven-coverage caution applies |
| Northern Territory | Source listed; general uneven-coverage caution applies |
Practical interpretation: Use South Australia as your depth benchmark. For other states, note the year and whether a name outside the top 50 or 100 would be invisible in the record. A "fall" in a name's national count may reflect a reporting cutoff rather than fewer births.
How to track a specific boy name's rise or fall
To follow one name, filter the dataset by name, sex = male, and a sequence of year values. The package's example for author names such as "Robert", "Mitchell" and "Nicholas" shows line charts of counts per year, demonstrating that the underlying data supports year-by-year tracking (ozbabynames).
A useful workflow:
- Choose the boy name you want to investigate.
- Read the Known Issues section for the states relevant to your question.
- Extract the count for each available year and state.
- Plot or tabulate the sum across states, but keep state limits visible.
Questions to verify before trusting the line: - Does the count for a given year include all states, or only those with data for that year? - If a state reports only top 100 names, a name outside the top 100 will show as missing—not because no boys were given that name. - The original state files linked from the ozbabynames site hold the authoritative scope. Confirm there before citing a trend.
We do not provide personalised advice, and we do not call any name or product "best". Popularity here is a registration count, not a quality judgement.
Reading trends without over-reaching
The dataset allows you to visualise rises and falls, as shown in the package's animated examples for selected names (ozbabynames). A correlation between a year and a count is not a cause. The data contains no field for migration waves, popular culture, or spelling variants; those sit outside the verified evidence.
Fact: South Australia's full series back to 1944 lets you see a name's trajectory across eight decades. Interpretation: If a name's summed national count dips in 2017, it may reflect Tasmania moving to top-10-only reporting rather than a real drop in births. Verify: Always label charts with the states included and the rank cutoff that applied that year.
When you see a published "most popular Australian boy names" list, check whether it notes these source limits. The ozbabynames compilation is a tool, not a finished national league table.
Concrete next steps to explore the data
If you want to run the analysis yourself:
- Access the package: Install the CRAN version with
install.packages("ozbabynames")or the development version from GitHub as described on the site (ozbabynames). If you do not use R, follow the linked state data.gov.au datasets to inspect the raw CSVs. - Inspect raw sources: The page links to each state's dataset. Open those to confirm whether your target year is "all names" or "top N".
- Build a checklist:
- [ ] Define the boy name and year range.
- [ ] Note South Australia as the longest back-to-1944 series.
- [ ] For each other state, record top-N limit or recent-data start.
- [ ] Sum counts only where comparable.
- [ ] Store the source date (the site references package version 0.2.0.9000).

This article summarises a public dataset for general informational purposes. It does not provide personalised legal, tax, migration, credit or financial advice, and it does not promise any outcome from using name data. Figures may change when source registries update.
