title: [Problems in definition and comparison of perinatal and infant mortality].
abstract: One of the reasons for variations in infant mortality could be the differences in registration of vital events. In this paper the legal definitions regarding spontaneous abortion, stillbirth and live birth are studied taking into account international and time related differences. One of the often cited influencing factors on registration--the religion--has possibly influenced differences between Swiss cantons before the sixties.
