"Figure 1: Number of members of occupational pension schemes by membership type","" "","" "","" "Notes","1. This is not a continuous time series. 2. The 1983 survey was the first that collected all three occupational pension scheme membership types. 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 and is therefore not included. 5. Changes to methodology for 2006 onwards mean that comparisons with earlier years should be treated with caution. 6. Changes to the part of the questionnaire used to estimate pensions in payment and preserved pension entitlements in 2008 mean that comparisons with 2007 and earlier should be treated with caution."
