As professionals and families work together to identify and celebrate the strengths and resources unique to each family, new and innovative ways to describe and discuss family characteristics are needed. The eco-map, borrowed from social science disciplines, is one method used to describe family strengths and resources. The eco-map was developed in 1975 by sociologist Hartman (1978) to help social workers in public child welfare practice better understand the needs of the families with whom they worked. An eco-map is a graphic representation or visualization of the family and linkages to the larger social system, including informal (e.g., friends, extended family members) and formal (e.g., early care and education providers, early intervention providers) supports. It illustrates how the family exists within the context of its relationships with other individuals and institutions with which the family has contact. Utilizing an ecological model, the eco-map provides a visual display of any group of interconnections and relationships, providing a graphic image of the family system within the larger social matrix. This article provides a brief overview of the eco-map process, describes the key steps in completing eco-maps with families, and shares implications for early intervention practice. The eco-mapping process is illustrated through the use of a family vignette. (Contains 3 figures and 1 table.)
