There are some ethnic neighborhoods with a long history of having a similar name across cities -- many Chinese neighborhoods are Chinatowns, Italian neighborhoods are called Little Italy, Greek neighborhoods are Greektowns across different cities. Others are names of the old country's cities like "Little Manila" or "Little Saigon", repeated across different cities.

What accounts for why some are named in the style of (name of country)-town, others are Little (name of country), and others are Little (famous name of city within the country), and the often repeated (though not always), consistency of names across the immigrants' neighborhoods in different cities?
Did the first city to have an ethnic enclave of the name basically inspire later immigrants in other cities to call it a similar thing? Some names are much more consistent than others (eg. Chinatown or Little Italy is usually pretty common, while say, little Russia or Little Moscow may not be that common). It sometimes doesn't necessarily have to do with how abundant the enclaves are either -- for example, Mexican neighborhoods are very common, but few are called "Mexicantown", and many simply go by their neighborhood's own name.
Is there a logic to ethnic neighborhood naming, whether the city gives it official or unofficial status as a name or even if it's just a local, informal name?
