WA's baby boom has been confirmed, with new figures showing a surge in the number of deliveries last year.
Data from the Registry of Births, Deaths and Marriages shows 33,920 babies were born last year, up 4.4 per cent on 2011. In comparison, there was only a 2.9 per cent increase in 2011 and a 1.6 per cent rise in 2010, after a 3.3 per cent decrease in 2009.
Many WA hospitals reported mini baby booms last year, with record deliveries at some, amid worsening maternity staff shortages across many public hospitals.
Mt Lawley's Mercy Hospital, formerly St Anne's, delivered 47 babies in one week, the most born in a week in the hospital's 75-year history.
Deaths were also on the rise in WA last year, with 13,605, a 4.6 per cent rise on 2011 figures.
The number of marriages also rose marginally, up from 12,664 in 2011 to 12,969 last year.
