Germany comprises sixteen states which are collectively referred to as Länder. Each state has its own state constitution and is largely autonomous in regard to its internal organisation. Because of differences in size and population the subdivisions of these states vary, especially as between city states and states with larger territories. For regional administrative purposes five states, consist of 22 Government Districts.
