The “abridged life table” looks like “complete life table”, but in fact it is compiled from 5-age data, using “interpolation method” to create single-age life table. In addition, the “regions” life table is due to the adjustment of the administrative regions in 2010 and 2014 respectively. The current administrative regions were started in 2014, so the “regions” life table is currently available from 2014. It should be noted that the “regions” life table is calculated by three years of demographic data. It means that the “regions” life table of 2019 uses the regions’ 2017-2019 demographic data, 2018 uses the regions’ 2016-2018 demographic data, and so on.
