"Cultural islands" typically refer to isolated or distinct cultural communities that are surrounded by a dominant or different cultural context. While the term is more commonly used in the context of communities within a larger society, it can also be applied metaphorically to groups that are isolated in various ways. Here are some examples:

Chinatowns: These are areas within cities, often in Western countries, where Chinese communities have established themselves with distinct cultural elements such as language, cuisine, and traditions.

Little Italy: Similar to Chinatowns, these are neighborhoods with a predominantly Italian cultural identity, often maintaining traditions, language, and cuisine from Italy.

Amish communities: The Amish people in the United States live in close-knit communities with their own distinct cultural practices, often isolated from the broader societal influences.

Hasidic Jewish communities: Certain Hasidic Jewish groups live in tightly knit communities with their own unique customs, clothing, and traditions that distinguish them from the surrounding culture.

Gated communities: While not defined by ethnicity, some gated communities can function as cultural islands, with residents sharing similar socioeconomic status, lifestyle preferences, and sometimes even cultural values, effectively isolating themselves from the broader community.

Monastic communities: Monasteries, convents, and other religious retreats can be considered cultural islands, as they often maintain a distinct way of life, separate from the secular world.

Academic or scientific communities: Research institutions and academic campuses can develop a unique culture and set of values, forming a sort of cultural island within the broader society.

Online communities: Virtual spaces, such as forums, social media groups, or gaming communities, can also function as cultural islands where members share common interests, values, and communication styles.

These examples illustrate that cultural islands can exist in various forms and are not solely dependent on physical geography. They can arise through shared interests, beliefs, or other factors that create a distinct cultural identity within a larger societal context.
