self-assessed that they had been raped by their husbands, ex-husband, or de facto husbands. The survey interviewers, however, classified 74 (12%) of these women as having been raped. Of the 286 non-married women in the sample, 228 (80%) were classified by the survey interviewers as having been raped. Russell found that when repeated instances of rape as classified by the survey interviewers, by husbands or ex-husbands, over the entire course of the marriage are included, these account for 38% of all rape instances, in comparison to the remaining 62% occurring in non-marital instances. David Finkelhor and Kersti Yllo published a study in 1985 on marital rape that drew on a scientifically selected area probability sample from the metropolitan Boston area of 323 women who were either married or previously married who had a child living with them between the ages of six and fourteen. The study found that of the women who were married the instance of sexual relations through physical force or the threat thereof was 3%. In 1994, Patricia Easteal, then Senior Criminologist at the Australian Institute of Criminology, published the results of survey on sexual assault in many settings. The respondents had all been victims of numerous forms of sexual assault. Of the victim sub-sample, 10.4% had been raped by husbands or husbands, with a further 2.3% raped by estranged husbands/de factos. In 2002 Basile published research intended to address the lack of a nationally probability sample to-date that measured intimate sexual coercion faced by married women. Data were collected in a 1997 national poll by a random telephone survey of 1,108 residents in the continental U.S. of persons 18 years old or older. The survey had a 50% response rate. Of the 1,108 respondents, the 506 men were excluded from any inquiry into unwanted sexual experiences, leaving 602 (54%) women respondents for the study. 398 (66%) women indicated no unwanted sexual relations (their marital status is not given), and 204 (34%) women responded as having engaged in unwanted sex after being subject to some level of sexual coercion; types of sexual coercion included receiving 'a gift', 'a nice dinner', 'a back rub', 'kissing', etc. through threatened harm and physical coercion. Of this group, a sub-sample of 120 (59%) were married, of which 9% responded as having been subject to physical force.
