This paper examines the diversity of experiences associated with grandparenting, as well as identifying factors that contribute to this diversity. The focus is grandparents in Canada, but international research is included as well. Following a list of highlights and an introduction, the paper addresses: (1) the demographic context of grandparenthood (e.g., what factors influence whether individuals will become grandparents?); (2) meanings associated with grandparenthood; (3) contact, help, and emotional closeness (e.g., how much contact do grandparents and grandchildren have with each other?); (4) sources of diversity in grandparent-grandchild relationships (e.g., geographic proximity, gender, age, race, and health); and (5) expectations and rights of grandparents.
