Application of the microcomputer to the estimation of adult survivorship by indirect techniques

This paper, the second in a series on the application of the microcomputer to the estimation of vital rates by indirect techniques, deals with the measurement of adult survivorship. Two of the most widely used techniques for the estimation of adult survivorship using indirect techniques are the Widowhood method and the Orphanhood method. A review of the Widowhood method, developed by Hill and Trussell, is given followed by a detailed description of the use of the computer program for the conditional regression variant of the method using data on age of respondents (widowed males or females). A full listing of the program, written in TRS-80 BASIC, is available on request. The program for the Orphanhood method will be given in a paper to follow.
