17.1. Data revision - policy | |||
In general terms, revisions are mainly due to new data on the past that could not be incorporated in time of their previous release. Annexes: Revisions policy |
|||
17.2. Data revision - practice | |||
Taking into account the diversity of revision factors and the different frequencies of computation of statistical variables, as well as international experience in this field, revisions can be classified as follows: (1) regular revisions (current or general) and (2) extraordinary revisions. Minor revisions might occur annually on vital events data. The annual postcensal resident population estimates are provisional and are reviewed for the intercensal years after the final data of the most recent population census. The series of resident population 2011-2020 based on the 2011 Census was subject to revision, in order to make it compatible with the results of the 2021 Census, in accordance with Statistics Portugal Revisions Policy, in particular the regular general revisions that follow statistical operations of structural nature. The revised annual intercensal series of resident population 2011-2020 based on the results of the 2021 Census was released on March 31st, 2023. At the same date, data on resident population for 2021, the first year of the new post-Census 2021 series, was released. Data on resident population for 2022 refer to the second year of the new series of postcensal estimates based on the 2021 Census. Annual estimates of emigrants and immigrants are reviewed every ten years along with the revision of the resident population estimates. |
