Dated versions never change. ## 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/nsw-bdm-registrations-monthly/rows. Counts and sums: https://publicdata.au/api/v1/datasets/nsw-bdm-registrations-monthly/aggregate. - Rows: https://publicdata.au/api/v1/datasets/nsw-bdm-registrations-monthly/rows?year=eq.2026&limit=5 - Aggregate: https://publicdata.au/api/v1/datasets/nsw-bdm-registrations-monthly/aggregate?group=month&metric=sum.births&year=eq.2026 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//` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets//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.

Open https://publicdata.au/d/nsw-bdm-registrations-monthly/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/nsw-bdm-registrations-monthly/v/2026-10-02/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 Births, deaths and marriages registered each month in Excel? Yes. https://publicdata.au/d/nsw-bdm-registrations-monthly/v/2026-10-02/data.xlsx is a workbook with the 141 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/nsw-bdm-registrations-monthly/v/2026-10-02/data.csv.gz is the CSV at about a tenth of the size. ### What years does Births, deaths and marriages registered each month cover? The current version covers 2015 to 2025. Each release from NSW BDM becomes a new dated version here, and earlier versions stay online. ### How often is Births, deaths and marriages registered each month updated? NSW BDM releases it monthly. This site checks the portal every week and adds a dated version when the file changes. ### Can I use Births, deaths and marriages registered each month 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 Births, deaths and marriages registered each month? No. The publisher is NSW Registry of Births Deaths and Marriages, and its page is https://data.nsw.gov.au/data/dataset/bdm-data. 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. ### What is in each row? One month since January 2015, with the number of births, deaths and marriages the Registry registered in that month. ### Are these the births and deaths that happened in the month? No. The Registry counts the registrations it completed in the month. A birth or death can be registered weeks after it happened, so a month's count is not the number of events that occurred in it. ### How often is it updated? The Registry adds the latest month to the file every month. ## 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`. ## Improve this dataset This page is built from [register/nsw-bdm-registrations-monthly.yaml](https://github.com/National-Digital/publicdata.au/blob/main/register/nsw-bdm-registrations-monthly.yaml) on GitHub, and a fix to it is welcome as a pull request. https://publicdata.au/contribute/ explains how.
