Most American families consist of three or more generations. This study analyzes intergenerational relationships over time. In the past these relationships have been characterized in terms of a generation gap. In regard to this gap, this study seeks to compare and contrast perceptions of generational relations among grandparents, parents, and children; analyze how these perceptions change over time; and examine around what issues family members perceive generational conflict. Data for the analysis were part of a larger longitudinal study of three generation families over a period of time. Responses to a question about perceived gaps between generations were analyzed. Systematic differences between generations in their perceptions of the generation gap within the family were found. Grandparents saw less conflict within their families than did either children or grandchildren. Grandchildren reported the greatest distance between themselves and other family members. Qualitative responses reflected intergenerational disagreements over the meaning of work and finances. (ABL)
