It is a unicameral institution, consisting of a total of 40 elected lawmakers representing single-member constituencies throughout Penang. The state legislature, whose members are called State Assemblymen, convenes at the Penang State Assembly Building in Penang's capital city of George Town. The Penang State Executive Council, the executive branch of the Penang state government, is drawn from among the State Assemblymen.
