6.3 The adjustment
The actual adjustment procedure consisted of creating homogeneous adjustment classes with similar
coverage rates within province – based on geography type, population group, sex, and age group – and
calculating a common population, undercount rate, and adjustment factor, for each class separately. The
national adjusted population was obtained by summing the adjusted classes. Only the population within
the scope of the PES received adjustment factors. The totals for the balance of population (namely,
people living in collective living quarters other than hostels, the homeless on the street, and those living
in out-of-scope EAs) were not adjusted (see Sections 5.5 and 5.6).
