Approvals vs migration

Dwelling approvals against net overseas migration, dwellings-required coverage.

history mode ABS

What it answers

Are we approving enough homes for the people arriving? This sets ABS dwelling approvals against ABS net overseas migration to estimate how well new supply covers population growth. It frames the housing debate as a coverage ratio rather than two unconnected headlines.

Call it

curl -H 'Authorization: Bearer ak_your_key' \
  https://api.ausdata.io/v1/approvals-vs-migration

History mode

Add start_period and end_period to walk the series back through time instead of returning only the latest point.

curl -H 'Authorization: Bearer ak_your_key' \
  'https://api.ausdata.io/v1/approvals-vs-migration?start_period=2015-Q1&end_period=2024-Q4'

Returns

Every response uses the same envelope, {data, meta, links}. The data field carries the answer (an object for a single snapshot, a list when there is one row per entity). The meta field carries the trust contract: the reference periods, retrieved_at, the per-source attribution you reproduce on publish, and the stale flag. The links field offers a csv alternative when one is available.

Draws from

This signal joins data from one source. Each source page lists the underlying datasets and canonical series.

Cross-source signals join multiple sources into one response. Reliability: a signal returns current data or a clear 503; it never serves an older vintage as the current answer.
