Who knows. Would NYC even be considered one "city", rather than a set of burroughs, for this purpose? Or are the names perhaps normalized by population? If so, would they remove outliers as many statistical packages will do for you, but in this case they should leave them in, so if they were removed automatically that would not be great. Or if they just went with one name = one count then is there a minimum cutoff? Or a nearness criteria e.g. places near NYC still get swept up into it? And like how much wood would a woodchuck chuck if a woodchuck could chuck wood? So many unanswered questions here...
