Component (a), the households included in both the census and the PES, was estimated at 9,51 million;
component (b), the households included in the census but missed in the PES, was estimated at 2,16
million; component (c), the households included in the PES but missed in the census, was estimated at
1,81 million; and component (d), the households missed in both the census and the PES, was estimated
at 0,41 million.
Table 15 shows that, of the 11,76 million households counted in the census for the in-scope subuniverse,
11,67 million are estimated to be correctly enumerated. Of these, the PES enumerated 9,52
million and missed 2,15 million. The census erroneous inclusions are estimated to be 0,78 million.

It is estimated that the census omitted 2,22 million households in total, 1,81 million of which were
correctly enumerated in the PES, and another 0,41 million of which were missed in the PES as well as in
the census (Table 16). This total omission does not take into account the erroneous inclusions.
