This is a list of obsolete occupations. To be included in this list an occupation must be completely, or to a great extent, obsolete. For example, there are still a few lamplighters retained for ceremonial or tourist purposes, but in the main the occupation is now obsolete. Similarly, there are still some manual switchboard operators and elevator operators which are required for historic equipment or security reasons, but these are now considered to be obsolete occupations. Occupations which appear to be obsolete in industrialized countries may still be carried out commercially in other parts of the world, for example charcoal burner.
