  1. Changing Residentail Patterns 1991 - 2001 Dan Vickers, Department of Geography, University of Sheffield UPTAP Conference 21 -23 March 2007

  2. Changing Residential Patterns 1991 - 2001 Background • Project scheduled to run 1st January 2006 – 31st December 2006, in the School of Geography, University of Leeds. • PhD handed in Friday 13th January 2006. • Viva started a year ago to this minute across the corridor. • 1st September 2006 Appointed ‘Lecturer in Social and Spatial Inequalities’ in the Department of Geography, University of Sheffield. • Therefore only able to complete 8 out of the scheduled 12 months of the project. • Rearranged schedule to complete the research one day a week, to be completed by the 1st September 2007.

  3. Changing Residential Patterns 1991 - 2001 Research • Original idea: To attempt to examine the change in residential patterns over time using geodemographic techniques. • Why So? • My PhD created the national classification of output areas for the ONS http://www.statistics.gov.uk/about/methodology_by_theme/area_classification/default.asp • The classification show distinct and clear residential patens. • Click for map: http://www.casa.ucl.ac.uk/googlemaps/OAC-super-EngScotWales.html

  4. Changing Residential Patterns 1991 - 2001 Research • Variable selection. • Can the variables be compared across time? • Can the whole UK be used? • Matching the geography. • Methodology. • Two years separately or all together. • Transformation? • Standardisation. • Method of Clustering. • How many clusters? • Results so far

  5. Changing Residential Patterns 1991 - 2001 Research • Variable Selection • Social Class a/b • Social Class c1 • Social Class d • Social Class e • Non White

  6. Changing Residential Patterns 1991 - 2001 Research • Matching the Geography • 1991 data assigned to 2001 geography using population weighted centriods.

  7. Changing Residential Patterns 1991 - 2001 Research • Methodology • Data ranked then standardised between 0 -1. • K-means clustering used. • Both years clustered together. • Looking at between 2 – 7 clusters.

  8. Changing Residential Patterns 1991 - 2001 Research 2001 • Results so far 1991 In the same group: 99,927 (60.3%) In different group: 65,738 (39.7%) Cluster 1: -7,675 Cluster 2: -12,964 Cluster 3: +20,639
