Whatever the person that wrote it wants to call it. Symphonies can have all sorts of variations in number of movements. Stravinsky wrote a piece he called "Symphony in Three Movements". Mozart's "Prague" Symphony (No. 38) has only three movements and is sometimes called the symphony without a minuet. Schubert's "Unfinished" Symphony only has two movements, thought presumably it was not planned that way. In the final consideration, it's best simply to go with whatever the composer called it.
