Crude Birth Rate Core Indicator

Total number of live births per 1,000 population

 

Method of Calculation


Crude Birth Rate:
total number of live births
1,000
total population
1,000


Recommended Subset Analysis Categories

Geographic areas of patient residence

Analysis Checklist  

Checklist

  • Exclude stillbirths.
  • The IntelliHEALTH licensing agreement does not require suppression of small cells, but caution should be used when reporting at a level that could identify individuals, (e.g. reporting at the postal code level by age and sex). Please note that privacy policies may vary by organization. Prior to releasing data, ensure adherence to the privacy policy of your organization.
  • Aggregation (e.g. combining years, age groups, categories) should also be considered when small numbers result in unstable rates.
  • Exclude births to mothers that reside out-of-province. Births to Ontario mothers that occur out-of-province are not included in the data.
  • Include all births, not just those for mothers aged 15-49 years.
  • Include live births with birth weight <500 g. For more information, refer to the Reproductive Health Core Indicators Documentation Report. 
  • HELPS Data: Historically, PHUs obtained data for live births, stillbirths, therapeutic abortions, congenital anomalies, and deaths from the Ministry of Health through HELPS (the HEalthPlanning System). Although these data are no longer commonly used, some PHUs may still be accessing these data files. Information about the data can be found in the HELPS Data Source resource.

Vital Statistics

  • In IntelliHEALTH under Standard Reports, folder "01 Vital Stats", open "Birth Summary V2". This report summarizes information on births by age group and mother's residence (Ontario, PHU and LHIN). IntelliHEALTH also provides population data (total population, female population aged 15-49 years) for the calculation of rates. Refer to the Notes tab for information. Open tab "1.2 Births x PHU x Type x Age" to obtain public health unit data and tab "1.1 ON Births x Type x Age" to obtain Ontario data. The report can be modified, renamed and saved under your own folder or can be exported into Excel.
  • The predefined report provides live birth and population data for the calendar years from 2000 to the most recent available. Table options can be edited to change the number of years of data presented.  For years that are not displayed modify the calendar year filter to include the required years.
  • The data contained in the Birth Summary V2 report includes births to Ontario mothers in Ontario only.
  • The notes section of the report provides important data caveats and background information on data sources and should be consulted. 

Hospitalization

  • In IntelliHEALTH under Standard Reports, folder ‘05 Inpatient Discharges' folder, use the "Hospital Births - newborns, stillbirths" predefined report. This report can be modified, renamed and saved under your own folder. The report provides hospital birth counts (Admit Entry Type = N for Newborn or S for Stillbirth) for Ontario and by PHU, including only Ontario residents (Patient Province equal to ON).
  • The calendar year for date of admission is used (Admit CYear) rather than date of discharge since the date of admission will be the same as the birthdate for newborns.
  • Select the appropriate calendar years, PHU, and "Newborn - Born Alive in Reporting Institution" (i.e., exclude stillborn infants) as prompted from the pre-defined filters.
  • Even though counts are grouped by calendar year of admission, it is the actual number of discharges that are counted.
  • The notes section of the report provides important data caveats and background information on data sources and should be consulted. 

BORN

  • Public Health Units access the BORN data through public health reports or data cubes.
  • Refer to the BORN Information System resource for more information about the data.


Indicator Comments

General Comments

  • Crude birth rate is influenced by the age structure of the population - it will be higher in populations with more women of childbearing age (1).
  • Crude birth rate may be affected by foreign immigrant settling patterns within Ontario, the pattern of migration into and out of Ontario from other provinces as well as migration between jurisdictions within Ontario (2).
  • Total number of births, migration information as well as age structure of the population may be helpful when interpreting crude birth rates. 


Definitions

Live birth – the complete expulsion or extraction from its mother of a product of conception, irrespective of the duration of the pregnancy, which, after such separation, breathes or shows any other evidence of life such as heartbeat, umbilical cord pulsation, or definite movement of voluntary muscles, whether the umbilical cord has been cut or the placenta is attached. A live birth is not necessarily a viable birth.
