This data frame contains information about 3866 Welsh and English who died at age ranging from 105 to 110 between 2000 and 2014 (except for two women who died late in December 1999) and a subset of UK supercentenarians from the IDL database (5 male, 80 female) who died during the same period. 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 truncated.
