## Query

The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/au-births-by-state/rows. Counts and sums: https://publicdata.au/api/v1/datasets/au-births-by-state/aggregate.

- Rows: https://publicdata.au/api/v1/datasets/au-births-by-state/rows?year=eq.2024&measure=eq.Births&state_code=neq.AUS&limit=5
- Aggregate: https://publicdata.au/api/v1/datasets/au-births-by-state/aggregate?group=state&metric=sum.value&year=eq.2024&measure=eq.Births&state_code=neq.AUS

Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`.

- `select`: Fields to return, comma-separated. Every field when absent.
- `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent.
- `limit`: Rows per page, 1 to 10,000. 100 when absent.
- `offset`: Rows to skip. The `next` URL in each answer sets it for you.
- `group`: On `aggregate`, fields to group by, comma-separated.
- `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent.
- `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers.

Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions/<date>/` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets/<slug>/versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

## Questions

### How do I download Registered births, birth rate and sex ratio by state, Australia as a CSV file?

Open https://publicdata.au/d/au-births-by-state/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/au-births-by-state/v/2026-10-03/data.csv today. The same path serves Excel, JSON, Parquet, SQLite, DuckDB, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same.

### Can I open Registered births, birth rate and sex ratio by state, Australia in Excel?

Yes. https://publicdata.au/d/au-births-by-state/v/2026-10-03/data.xlsx is a workbook with the 4,500 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/au-births-by-state/v/2026-10-03/data.csv.gz is the CSV at about a tenth of the size.

### What years does Registered births, birth rate and sex ratio by state, Australia cover?

The current version covers 1975 to 2024. Each release from ABS becomes a new dated version here, and earlier versions stay online.

### How often is Registered births, birth rate and sex ratio by state, Australia updated?

ABS releases it yearly. This site checks the portal every week and adds a dated version when the file changes.

### Can I use Registered births, birth rate and sex ratio by state, Australia commercially?

Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file.

### Is this the official source for Registered births, birth rate and sex ratio by state, Australia?

No. The publisher is Australian Bureau of Statistics, and its page is https://www.abs.gov.au/website-privacy-copyright-and-disclaimer. This site republishes the publisher's file without changing its content. The original sits beside every version as source.csv with its SHA-256, so the two can be compared.

### How do I get only the rows for one measure?

Every version has one JSON file per value of measure, 10 files in the current version, listed with row counts at https://publicdata.au/d/au-births-by-state/v/2026-10-03/by/measure/index.json. For example https://publicdata.au/d/au-births-by-state/v/2026-10-03/by/measure/births.json holds the 450 rows where measure is Births.

### What is in each row?

One measure for one state or territory of usual residence, or Australia, in one year of registration since 1975. The measures are the number of births, male and female births, nuptial and ex-nuptial births, the estimated population, the crude birth rate per 1,000 people and the sex ratio of male births per 100 female births.

### Can I add the measures together?

Each row is a different quantity, and the measure column says what it is. Sum only the rows of one count measure, such as Births across the states, and never add a rate or the sex ratio.

### Is the year the year of birth?

It is the year the birth was registered. The state is the mother's state or territory of usual residence.

## What this site did to the data

Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.csv`.
