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 1 st January 2006 – 31 st December 2006, in the School of Geography, University of Leeds.  PhD handed in Friday 13 th January 2006.  Viva started a year ago to this minute across the corridor.  1 st 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 1 st 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_cl assification/default.asp http://www.statistics.gov.uk/about/methodology_by_theme/area_cl assification/default.asp  The classification show distinct and clear residential patens.  Click for map: http://www.casa.ucl.ac.uk/googlemaps/OAC-super- EngScotWales.html 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  Results so far 1991 2001 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
