Eco 572: Research methods in Demography Life Table Analysis of Contraceptive Use We will illustrate the application of life tables to the analysis of contraceptive effectiveness using a classic dataset from Tietze (1967) Intra-Uterine Contraception: Recommended Procedures for Data Analysis. Studies in Family Planning 1:1-6. The data come in two tables, one showing first insertions per calendar month, and another giving details of terminations and reinsertions. Both tables are available in the datasets section of the course website as TietzeInsertions.dat and TietzeTerminations.dat . I did some preliminary work to put the data in a more usable form. The manipulations are simple but tedious. If you are interested, my do file is available as TietzeData.do . The final result is a file that shows insertions, terminations, reinsertions, continuations, and details of events and closures by ordinal month of use. . use http://data.princeton.edu/eco572/datasets/Tietze . desc Contains data from http://data.princeton.edu/eco572/datasets/Tietze.dta obs: 15 vars: 19 15 Mar 2006 13:46 size: 2,100 (99.9% of memory free) ------------------------------------------------------------------------------- storage display value variable name type format label variable label ------------------------------------------------------------------------------- month float %9.0g Ordinal month of use ins float %9.0g First Insertions terms float %9.0g Terminations reins double %9.0g Reinsertions cont float %9.0g Continuing Segments ap double %9.0g Accidental Pregnancy (e) fe double %9.0g First Expulsion (e) le double %9.0g Later Expulsion (e) rm double %9.0g Removal for Medical Reasons (e) rp double %9.0g Removal for Personal Reasons (e) ric double %9.0g Removal at Investigator's Choice (e) lfu double %9.0g Lost to Follow Up (e) cap double %9.0g Accidental Pregnancy (c) cfe double %9.0g First Expulsion (c) cle double %9.0g Later Expulsion (c) crm double %9.0g Removal for Medical Reasons (c) crp double %9.0g Removal for Personal Reasons (c) cric double %9.0g Removal at Invertigator's Choice (c) clfu double %9.0g Lost to Follow UP (c) ------------------------------------------------------------------------------- Sorted by: http://data.princeton.edu/eco572/tietze.html (1 of 6) [2/12/2008 10:39:14 AM]

Eco 572: Research methods in Demography Woman-Months of Exposure The first task is to compute exposure. We start with all first insertions and each month add reinsertions, and substract terminations and continuations. We compute exposure assuming a uniform
