How were the permitted areas worked out?
The Gaming Clubs (permitted areas) Regulations 1971 included a formula under which any county borough outside Greater London with a population of 125,000 became a permitted area. When county borough were abolished in 1974, the formula was altered so as to bring in those former county boroughs which had a population of 125,000 or more at any time between 01 December 1970 and 01 October 1973. The list has remained frozen ever since. There is no match between the current local government areas and casino permitted areas.
