Statistics are most often revised for 1 of 2 reasons:

  1. For certain statistics initial estimates are released with the expectation that these may be revised and updated as further data becomes available.
  2. Revisions may also be made when methods or systems are changed.

These types of planned revisions should not be confused with errors in released statistics, which are genuine mistakes. Such mistakes occur rarely and, when they do happen, corrections are made in a timely manner, announced and clearly explained to users in line with the Code of Practice for Official Statistics (Principle 2, Practice 7).

Important notes and usage information

Census information on general health and disability is used to smooth the health state prevalence seen in Annual Population Survey (APS) data. Previously, we used 2011 Census data for those purposes in estimating health state life expectancies between 2011 to 2013 and 2018 to 2020. With Census 2021 data available, we improve the accuracy intercensal prevalence used in imputing and fitting health state prevalence. We use linear interpolation between the health state prevalence seen at Census 2011 and at Census 2021 to create period-specific estimates of health state prevalence for the intervening years 2012 to 2020. Linear interpolation estimates the value of function between two known values; in this case the prevalence seen at the 2011 Census and 2021 Census.
