Unexplained differences in sex ratios at birth in Europe and North America

Abstract

sent memorandums pointing out any errors and omissions every six months.In 1996-7, the failure rate for bodies from all sources was 10.2% (table).This figure fell in the study period to 2.9% in 1999-2000.The bodies received from the hospital accounted for most cases of failed documentation.When the failure rate was calculated for hospital deaths alone, it fell from 11.9% in 1996-7 to 4.0% in 1999-2000.
