Household weights are created during database creation by using control totals from Statistics Canada's population projections. A more detailed description of the SPSD database creation procedure can be found in the Database Creation Guide, which is part of the SPSD/hI Reference Manual (Statistics Canada, 1989d; see also Wolfson et al., 1989~.

and by the SPSD/M operating characteristics (see Operating Characteristics below)

· All new variables calculated by the database adjustment procedure and the operating characteristics would be stored only in in-memory SPSD/M data structures to permit these variables to be accessed by the operating characteristics or the SPSDiM output facilities (see Output Facilities below)

Many of these decisions were based on the philosophy of trading off disk space for calculation time. For example, if a user has two different scenarios that alter only one parameter to one operating characteristic, SPSD/M would require two complete runs of all operating characteristics since the system does not support saving the intermediate output of the model runs.
