RENEW Key Facts
Although some of these facts relate specifically to Stoke on Trent, the issues are reflected in the other intervention areas across North Staffordshire.
• Between 1999 and 2003, Stoke on Trent lost 1,450 residents a year
• In the last 50 years, the population of the old Six Towns has halved • 7000 homes (4.3%) across the conurbation are empty. In central areas this
rose from 7.7% to 9.4% during 2005
• If new build and clearance continued at past rates, it was estimated that there would be a surplus of 20,000 homes
• The original RENEW prospectus recommended 14,000 properties be cleared and replaced with 12,000 new build properties. However, the clearance figures have now been greatly reduced
• If economic and Housing Market Renewal strategies are successful, it is estimated that we will stop losing population by 2011, and bring the number of empty properties down to a normal level by 2021
