How to read the data

What is counted

These are IDDEEA registrations, not an estimate of births to residents. Place and timing of registration, record changes and administrative practice can affect the number.

Privacy rule

A value is withheld only when one protected value could be calculated from the displayed aggregate.

Values below five are not shown. A missing source value is never zero.

Future context data

Official BHAS demographic data are documented as candidates but are not mixed into this service until their licence, definitions and geography are audited against IDDEEA.
