Introduction

This concept provides a look at Manitoba data on residential persistence, defined as the percent of residents living in the same postal code year after year, and the correlations of mean household income (Socio-Economic Status (SES)) of these individuals during the same time period. The data is based on:


• 1978-1987 birth cohorts (except 1983 cohort),
• MCHP enumeration area-level income based on 1991 census data, and
• a data sample of approximately 100,000 (all children).

The information presented below provides feedback on two questions asked in Kunz, J et al. (2003) :


1. How persistent is residence in the same area (postal code) ?
   
2. How good a proxy is mean household income at the census area level from one point in time with such income at a different time ?


Table A: Residential Persistence (the percent of individuals living in the same postal code year after year)

1992	.	91.9	83.3	78.3
1993	.	.	89.3	83.4
