Although I cannot extrapolate from my detailed findings about the PTA problem in the Arnhem Land homelands to the Northern Territory more generally, the overwhelming impression that I gained from being present at the CMU checking exercise when other areas were under scrutiny was that the problem would have been of the same order in many places. This is the key issue that emerges from this particular census exercise. It is a complex dilemma and the solution—which will never be perfect—is also complex, depending as it does on changes at many stages of the census exercise and at many sites within the ABS as an organisation. In the concluding chapter, we elaborate on these findings and make some recommendations for changes that will go some way to addressing them in the lead-up to the 2011 Census. In Appendix B, we discuss aspects of the IHF form design that probably contributed to the problem.
