Where someone is from is always variable, on multiple levels.
- First, the scope will vary; someone might be from Europe at a very broad level, or from a particular block of a particular street of a particular neighborhood of a particular district of a particular town.
- Second, the place with which a person identifies or is identified will vary. For some people, it is their birthplace, for others, their childhood home, still others various locations with which they have the strongest emotional ties, or lived the longest, or had their first success.
- Third, whether a place will lay claim to you may vary. Residents of transient cities may only recognize those born and bred there to be from there; residents of staid locales may consider you an outsider if your family has not lived there for generations. On the other hand, a place may lay claim to some celebrity or dignitary for the most tenuous of connections.
- Fourth, being from a place may refer to other aspects of one's identity, as for example when representing an employer or other affiliated organization: the lady from the pharmacy; the senator from Florida.
Wikipedia is not consistent in this matter. Most lists of people include those who "were born or have lived in" or more broadly were "associated with" the city; its list of people from San Francisco encompasses
people who were born/raised in, lived in, or spent portions of their lives in San Francisco, or for whom San Francisco is a significant part of their identity, as well as music groups founded in San Francisco
and its list of people from Taunton, Massachusetts, strangely, includes those who were buried within the city limits. Its list of people from Hebron, on the other hand, only includes those born there.
There may be cultural differences at stake; in the U.S., for example, it is not uncommon for families to relocate hundreds or thousands of miles away, and especially in the professional classes in the large metropolitan areas, a large proportion of the population will be from elsewhere. I had lived in six different houses by the time I was age 8. I have almost no memory, emotional ties, or other associations with the place where I was born, a small town to which my father had moved for graduate school, and from which we departed as soon as he had defended his dissertation. Rather, if someone asks where I'm from, I usually say "California," where I spent the largest proportion of my school years.
