"Figure 6: Number of preserved pension entitlements in occupational pension schemes by sector, 1991 to 2013","" "UK","" "","" "Notes","1. This is not a continuous time series. 2. Private and public sector breakdowns are not available for preserved pension entitlements before 1991. 3. Due to changes in the definition of the private and public sectors, estimates for 2000 and onwards differ from earlier years. From 2000, organisations such as the Post Office and the BBC were reclassified from the public to the private sector. 4. The 2005 survey did not cover the public sector. 5. Changes to methodology for 2006 onwards mean that comparisons with 2005 and earlier should be treated with caution. 6. Changes to the part of the questionnaire used to estimate preserved pension entitlements in 2008 mean that comparisons with 2007 and earlier should be treated with caution. 7. Components may not sum to totals due to rounding."
