2022 revision of benchmark population

Released on March 4, 2022
Revised on May 13, 2022

[Note]
    The benchmark population for calculating the results of the Labour Force Survey is revised every five years according to the release of the latest results of the Population Census which is conducted every five years.
    The benchmark population was revised to the 2020 Census-based population estimates in January 2022 for Basic Tabulation, and in Jan.-Mar. 2022 for Detailed Tabulation.
    Accordingly, the past data in materials released after the revision (excluding rate) was revised to the retroactive or adjusted time-series data based on the 2020 Ccensus-based (new criteria) benchmark population.

    The outline of the time-series data is as follows.

<Basic Tabulation>
  1. (1) September 2020 to December 2021
    Retroactive adjustment data based on the new benchmark population
  2. (2) October 2015 to August 2020
    The gap between the retroactive adjustment data (new criteria) for September 2020 calculated as (1) above and the initially released data (old criteria) (new criteria - old criteria) equitably distributed to the initially released data (old criteria) of each month (data with intercensal-level adjustment)
<Detailed Tabulation>
  1. (1) Oct. - Dec. 2020 to Oct. - Dec. 2021
    Retroactive adjustment data based on the new benchmark population
  2. (2) Oct. - Dec. 2015 to Jul. - Sep. 2020
    The gap between the retroactive adjustment data (new criteria) for Oct. - Dec. 2020 calculated as (1) above and the initially released data (old criteria) (new criteria - old criteria) equitably distributed to the initially released data (old criteria) of each month (data with intercensal-level adjustment)
