Rationale |
Low birth weight can add to length of hospital stays and health care costs. Over the fiscal years, these rates have continued to vary among provinces and territories. Given this variability, this indicator can be used to inform government planners, policy-makers, health system decision-makers, health care providers, patients and the general public. It can help raise awareness and allow Canada to compare its rates with the rates of other countries. |
Interpretation |
Lower rates for this indicator are desirable. |

As of 2015–2016, the national results include non-residents of Canada. |
Caveats and Limitations |
In order to provide a more stable rate estimate, only data from regions with a population of at least 75,000 (from 2001–2002 to 2005–2006) or 50,000 (from 2006–2007 to 2014–2015) was reported. Additional indications for suppression were rate instability and under-reporting. As of 2015–2016, regions are not suppressed based on population; however, numerator and denominator volume thresholds are applied for reporting. |
Trending Issues |
As of 2006–2007, all provinces and territories submit in the International Statistical Classification of Diseases and Related Health Problems,10th Revision, Canada (ICD-10-CA) and Canadian Classification of Health Interventions (CCI) coding classification systems; for this reason, Canadian rates are provided only from 2006–2007 onward. Results are presented for a patient's region of residence, rather than the location of the facility where hospitalization occurred. For Prince Edward Island and the territories, the entire province/territory is included as a region. Health regions in Nova Scotia and Alberta have changed over time. The Postal Code Conversion File (PCCF/PCCF+) was used to assign patients to their region of residence. As of 2015–2016, the national results include non-residents of Canada. Nunavut did not submit data to CIHI in 2002–2003. Data from Region 6 in New Brunswick in 2004–2005 was suppressed due to incomplete data submission. Data from this region was excluded from the provincial rate. Data from Peace Country in Alberta in 2006–2007 and 2008–2009 was also suppressed due to incomplete data submission. 2016–2017 data for Nunavut is incomplete; indicator results have therefore been suppressed. |
