The ozbabynames dataset lets you compare Australian girl and boy names by sex, state and year, but the comparison is limited by uneven state coverage rather than a single national tally. The ozbabynames package provides the dataset ozbabynames, which contains popular Australian baby names by sex, state and year (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
You cannot read the data as “girls’ names are more or less popular than boys’ names” overall, because the underlying counts are incomplete and inconsistent across jurisdictions.
What the dataset actually contains
The ozbabynames dataset is built from state and territory registries. It records year, state, sex, name and count for popular Australian baby names (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
A direct girl-versus-boy comparison is possible only where both sexes have usable counts for the same state and year. The package itself demonstrates this by grouping names by sex and name to show the top ten male and female names in 1952 (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
Where the coverage is uneven
The publisher states the coverage is very uneven: some states provide only recent data, and some provide only the top 50 or 100 names (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
Key limitations to note before comparing girl and boy names:
- The ACT does not provide counts, so no ACT data are included (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
- South Australia has by far the best data, with full coverage of all names back to 1944 (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
- Tasmania provides only the top 10 by rank after 2016 (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
This means a girl name in South Australia can be compared against all boy names from 1944 onward, while the same comparison may be impossible or truncated in another state.
How to compare girl and boy names correctly
To compare Australian girl names with boy names in the data, filter by the same state and year for both sexes. For example, the package documentation filters year == 1952, groups by sex and name, sums count, and shows the top names per sex (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
Practical steps:
- Choose one state with usable coverage for your target years.
- Set the same
yearrange forFemaleandMale. - Check whether the state limits results to a top-N list.
- Compare counts only within that state and year band.
Do not combine states blindly. Missing ACT counts and top-50 caps in some states will distort any national girl-versus-boy total.
What the data does not tell you
The dataset shows recorded counts by sex, not cultural meaning, future ranking, or approval of any name. It is a factual record from published state sources, not a recommendation.
You should verify the following before publishing or relying on a comparison:
- Which states are included for your chosen years?
- Does the state restrict data to top 50, top 100, or top 10 after a certain year?
- Are you comparing like with like (same state, same year, same sex field)?
The original state sources are linked from the ozbabynames site, including South Australia, New South Wales and Tasmania datasets on data.gov.au (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
Quick reference table
| State / Territory | Data note from ozbabynames |
|---|---|
| ACT | No counts provided; excluded |
| South Australia | Full coverage of all names back to 1944 |
| Tasmania | Only top 10 by rank available after 2016 |
| Other states | Some recent-only or top 50/100 limits |
This table summarises the publisher’s stated known issues and is not a full state-by-state specification (ozbabynames, https://pkg.robjhyndman.com/ozbabynames/).
Next step
If you want to compare Australian girl names with boy names, start with South Australia in the ozbabynames for the longest consistent series, then check whether your chosen state and year are subject to top-N limits.
