If you have missed your targets, or merely need to ensure that the numbers balance to a particular proportion, Data Squirrels can help with calculating the weight variables. Target or rim weighting is also possible if your proportions are based on multiple variables. Delivery can be done either as an added variable in your SPSS file or as an Excel output.
It may also be possible for Data Squirrels to assist in sourcing nationally representative targets depending on the country or region at hand. Do not hesitate to ask for more information.
