Final answer:
A small, close-knit neighborhood with a strong community is known as a gemeinschaft society, which embodies close relationships and social solidarity.
Step-by-step explanation:
According to sociological terminology, a very small, tight-knit neighborhood with a strong sense of community would be referred to as a gemeinschaft society. This term contrasts with gesellschaft society, which typically refers to larger, more impersonal groups often found in urban areas. Gemeinschaft societies are characterized by close personal relationships, strong family ties, and a sense of social solidarity that is usually found in traditional or rural communities.
