Some have estimated year of birth counted from age at death. Date of death is listed. So for instance someone who died in July 2016, and the age at death was said to be 72, it often says something like 1944 at their YOB but they could have been born 1943.
I remember when the 1881 census was on FamilySearch IGI 20 years ago, and estimated years of births was listed on the electronic database itself for people calculated on age given on census. Of course the YOB was not given on the actual 1881 census returns.
I found a William Coombs aged 55 in 1881 in Somerset and the database said "1826" as his year of birth.
