An issue has been identified with how the components of net undercount were created for the 2016 PES estimates. The contact sector should include PES respondents who were missed by Census because their dwelling was mistakenly deemed unoccupied on Census night. It was identified, however, that these respondents were erroneously treated as part of the non-contact sector. This error affected approximately 700 (unweighted) records, which have now been corrected.

Changes have been made to the contact and non-contact sector estimates. In particular,

    • Net undercount in the contact sector increased by 159,334 persons, driven by an increase in gross undercount (131,813 more persons) and a small decrease in gross overcount (27,521 fewer persons)
    • Net overcount in the non-contact sector increased by 159,334 persons
    • The 2016 PES population estimates and total net undercount rates have not changed.

These changes can be found in the following sections of this publication:
