I Have the honour to submit to the Faculty six Life Tables based on the population of Scotland as ascertained at the Census of 1921 and on the deaths registered during the years 1920 to 1922. Of the six Tables three deal with the male population and three with the female population, the three of each sex consisting of a general Table, a Table applicable to the married, and one applicable to the unmarried. The widowed population and deaths of widowers and of widows are included with those of the married.
