Constructing the SEFI (1996) Score

Date: October, 2001

1. Census data and source

Note:  The Unemployment and Education variables were combined using principal components analysis when calculating SEFI.  The factor weightings for axis one are used in place of the individual variables.
  • For a full discussion of each variable, see the MCHP deliverable Socio-Economic Characteristics Population Health Information System 1991/92 - 1986 Census Version, pages 34-37.

  • 2. Aggregating Census Data

    Physician Service Areas are geographic sub-regions of Manitoba RHAs based on physician utilization patterns.  Using census divisions or nearest neighbour analysis may be alternative methods for defining areas for imputation.
