sammanlevande

Sammanlevande is a Swedish term used to describe situations in which living beings share a space and time, often across species or human groups. The word combines samman (together) and leva (to live).

In ecology, sammanlevande describes where different species inhabit the same ecosystem and interact in ways that affect each other's lives. Interactions may include competition, predation, mutualism, or commensal relationships. The term emphasizes overlap in space and time rather than a preferred type of interaction.

In sociology and urban studies, sammanlevande refers to human communities that coexist in shared environments—such as neighborhoods, workplaces, or public spaces. It encompasses cultural and socioeconomic diversity, as well as the practices, institutions, and policies that allow diverse groups to live side by side.

The term is broad and context-dependent, and it is used more as a descriptive concept than a fixed scientific category.

Related concepts include coexistence, symbiosis, mutualism, and commensalism.
