Concept: Small Areas in Manitoba

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.

Manitoba Health Defined Areas

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
  
• moderate to high risk

Census / Stats Canada Areas

2065 enumeration areas

• Area canvassed by one census representative. Smallest census area.
  
• Usually less than 500 people
  
• moderate to high risk

150 Census tracts

• 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
  
• Low risk of individual ID (note some FSAs are small)

24000 Postal codes

• Typically a block face or small area.
  
• Represents very small numbers of people.
  
• High risk of individual ID at any level.
