Which term describes someone who is overly concerned with a specific region or area?

The term "provincial" is used to describe someone who has a narrow or limited view that is often focused on a specific region or area. This word derives from the concept of a "province," which refers to a particular area or region within a larger country. A provincial person may exhibit a strong attachment to local customs, traditions, or practices and may disregard broader perspectives or ideas that come from outside their immediate environment. This characteristic is often associated with a limited worldview, where an individual prioritizes local concerns over more global or universal issues.

The other terms do not carry this specific meaning. For example, a recluse refers to someone who prefers solitude and lives away from the company of others, while mediocre describes something that is average or ordinary, lacking distinction. Erratic indicates unpredictability or inconsistency in behavior, which is unrelated to a focus on a particular region or area. Hence, "provincial" is the most fitting term for someone overly concerned with a specific locality.
