"In this paper a simple method is presented to derive current adult mortality level.  The sensitivity of estimates to various forms of data error is considered, and procedures are proposed for removing errors resulting from differential census coverage completeness and from age misstatement.  The estimated life expectancy at age 5 derived from the method seems plausible."  The method is applied to census data for Bangladesh to estimate adult mortality for the period 1974-1981.
