factor for the quality flag; yes for validated records, no for unchecked records

ddate

second upper truncation bound (in days) corresponding to the maximum age by 2021 of semisupercentenarians who could have reached 110 before then

Details

All records for people who died at age 109 and all men, plus a stratified sample of the women were validated by the General Register Office (GRO). Observations are doubly interval truncated: some individuals could have been observed over distinct intervals if they died between 105 and 110 before 2014, but could have reached 110 before the end of the collection period.

The referenced technical report from ONS describes the validation procedure in more details and includes (approximate) sampling weights for the validation of the sample of women who died age 105-108.
