Currently, census data supplied to us has already been subjected to statistical disclosure control methods, such that small counts are suppressed before the data is put onto the system - this can affect the accuracy of query results

• Currently, census data supplied to us has already been subjected to statistical disclosure control methods, such that small counts are suppressed before the data is put onto the system - this can affect the accuracy of query results

• Where some new datasets will be supplied in primary unit form, this offers us the opportunity to only apply statistical disclosure control where it is necessary, thus increasing data accuracy for the end user

• Different techniques will need to be trialled and evaluated before data is made widely available
