The re-engineered GPSJS retained many items from the Victims of Crime Survey (VOCS), while new content was added. 
The GPSJS was conducted for the first time in South Africa in 2018/19 as an updated version of the long-running VOCS to include themes on governance. The rule of law and control of corruption were the only themes or sub-themes covered by VOCS prior to 2018. To achieve a reasonable balance between questionnaire length and depth of questions, a three-year rotation regime was adopted where the five themes are spread over a three-year period. Once in three years, the GPSJS will measure, in detail the general experience (including perceptions) of crime experienced by households and individuals in the country.
Note that government services corresponds to home affairs.
