Appendix A: Comparison with Original Estimates of Jewish Incidence
The population estimates derived from the results of the demographic survey fall close to the
original estimates calculated ahead of the fielding of the survey. These original estimates are
based on existing data available and were used as a planning guide for expected incidence for
the demographic survey; they were not used for calculation of the population estimates above.
