It depends I think.
Talking of this I have done some research into certain registration districts where my ancestors lived, and often they change boundary or a chunk of one district is transferred to a new district.
For example the Yarmouth registration district in Norfolk from 1837 to 1923 had just Great Yarmouth and Gorleston. From 1924 to 1939 the Yarmouth district gained the whole district of Flegg which was Hemsby, Martham, Rollesby, Scratby etc. And in the civil registration indexes, they come under "Yarmouth" but the certificates themselves says "Yarmouth and Flegg". It is unclear if the registers for Flegg were transferred to the Yarmouth main office, or stored where they were when it was Flegg.
So someone born in Martham in say, 1927, their birth would appear in the civil reg indexes as "Yarmouth" making you think they were born in the town itself, but by 1927 Yarmouth gained the Flegg districts which was outside Great Yarmouth itself.
