The current districts exist since 1996 , which at first had their own offices , but in 2004 , they were abolished and replaced by the Circuit Offices , which are usually responsible for several districts ( except for the NovÃ ZÃ mky District , which has two Circuit Offices ) , reducing districts to a little more than statistical units .
While both Regions and municipalities are currently both units of state administration and self-governing entities , the districts are little more than statistical units . In the late 20th century , the situation was different in that each district had its own District Office ( OkresnÃ 1\/2 Ã rad ) , representing the state in the district , but as from January 1 , 2004 these offices were abolished and replaced by Circuit Offices ( ObvodnÃ 1\/2 Ã rad ) , which are usually responsible for several districts ( except for the NovÃ ZÃ mky District , which is one district with two Circuit Offices ) and have little responsibilities .
