Introduction

The following document provides some basic information on various areas in Manitoba. Many of these have separate individual concepts written about them. This information is compiled from various sources; some numbers may disagree between sources and should be assumed to be approximate.

12 RHAs
• approximately 1200 to 650000 (Churchill and Winnipeg) - the rest are between 23000 and 95000.
  
• These areas are issues really only when dealing with small age ranges, or specific diseases/mortality
  
• Low risk of being too small to be statistically valid (except Churchill)

50-60 RHA districts and Physician Service Areas

• approximately 1000 - 45000
  
• Most in range 3000 - 10000 - starting to have issues with small numbers
  
• Moderate to risk (note some smaller areas)

283 Municipal areas

• Smaller areas than above districts range outside Winnipeg
  
• 30 - 30000
  
• Outside Winnipeg typically less than 1000
  
• Winnipeg has municipal areas defined by Manitoba Health but rarely used as such, these represent 6000 - 60000 (typically over 20000)
  
• Moderate to little risk

12 Winnipeg Community Areas

• approximately 31000 - 71000
  
• Similar to RHA where there are issues only with rare events
  
• Little risk

25 Winnipeg Neighbourhood Resource Networks

• Similar to districts above range 3400 - 37000 with most in 10000 - 17000 range
  
• moderate to low risk

228 Winnipeg neighbourhoods

• Small often under 1000

• Area canvassed by one census representative. Smallest census area.
  
• Usually less than 500 people

• Small geographic units representing urban or rural neighbourhood like areas similar in size to Winnipeg neighbourhoods but some are found outside the Winnipeg boundary.
  
• Moderate to high risk

334 Census subdivisions

• Very similar to municipal areas in size. Winnipeg is a single unit (650000)
  
• Moderate to little risk - not first nations communities identified with higher risk.

Postal Areas

61 FSA - Forward sortation areas

• Range is from 1 - 50000
  
• Typically over 20000 though
