Which group may form based on geographical locality?

The formation of a retirement community is primarily influenced by geographical locality. These communities are often established in specific areas where individuals of similar ages and backgrounds gather, typically in warmer climates or regions conducive to retirement living. Residents often choose these communities based on their proximity to amenities, social activities, and healthcare facilities, creating a shared environment that fosters relationships among neighbors.

In contrast, the other options, such as friends from school, online gaming squads, and professional colleagues, do not necessarily depend on geographical locality for their formation. For example, school friends may originate from various areas, online gaming communities transcend geographical boundaries, and professional colleagues can work together regardless of their physical location. This strong reliance on a specific geographical area makes retirement communities distinct in their formation compared to the other groups.
