Changes to the data made between Release 5.0 (Jan 2007) and Release 5.1 (Mar 2007)

Changes to Wave 5 files between Releases 5.0 (Jan2007) and 5.1 (March 2007)

Cross wave Subset of history variables

• Calendar calculations were incorrectly overlapping by one time period (0.03 year) which affected time since leaving school (_ehtse, 103 cases)/ time since leaving school in paid work (_ehtjb, 68 cases)/ time since leaving school unemployed and looking for work (_ehtuj, 17 cases)/ time since leaving school not working and not looking for work (_ehto, 19 cases).
• Time in current marital status variables were incorrectly set to -4 when there was an intervening period of defacto which ended and the respondent reverted to their prior marital status. Affected a handful of cases for time in current marriage (_mrcdur)/time widowed (_mrwdur)/time currently separated or divorced (_mrsdur). These are now calculated each wave after bringing forward the marriages grid, rather than attempting to update the derived variables from previous waves.
