Administratively, Baghdad Governorate is divided into districts which are further divided into sub-districts. Municipally, the governorate is divided into 9 municipalities, which have responsibility for local issues. Regional services, however, are coordinated and carried out by a mayor who oversees the municipalities. There is no single city council that singularly governs Baghdad at a municipal level. The governorate council is responsible for the governorate-wide policy. These official subdivisions of the city served as administrative centers for the delivery of municipal services but until 2003 had no political function. Beginning in April 2003, the U.S. controlled Coalition Provisional Authority (CPA) began the process of creating new functions for these. The process initially focused on the election of neighborhood councils in the official neighborhoods, elected by neighborhood caucuses. The CPA convened a series of meetings in each neighborhood to explain local government, to describe the caucus election process and to encourage participants to spread the word and bring friends, relatives and neighbors to subsequent meetings. Each neighborhood process ultimately ended with a final meeting where candidates for the new neighborhood councils identified themselves and asked their neighbors to vote for them. Once all 88 (later increased to 89) neighborhood councils were in place, each neighborhood council elected representatives from among their members to serve on one of the city's nine district councils. The number of neighborhood representatives on a district council is based upon the neighborhood's population. The next step was to have each of the nine district councils elect representatives from their membership to serve on the 37 member Baghdad City Council. This three tier system of local government connected the people of Baghdad to the central government through their representatives from the neighborhood, through the district, and up to the city council. The same process was used to provide representative councils for the other communities in Baghdad Province outside of the city itself. There, local councils were elected from 20 neighborhoods (Nahia) and these councils elected representatives from their members to serve on six district councils (Qada). As within the city, the district councils then elected representatives from among their members to serve on the 35 member Baghdad Regional Council. The first step in the establishment of the system of local government for Baghdad Province was the election of the Baghdad Provincial Council. As before, the representatives to the Provincial Council were elected by their peers from the lower councils in numbers proportional to the population of the districts they represent. The 41 member Provincial Council took office in February 2004 and served until national elections held in January 2005, when a new Provincial Council was elected. This system of 127 separate councils may seem overly cumbersome; however, Baghdad Province is home to approximately seven million people. At the lowest level, the neighborhood councils, each council represents an average of 75,000 people. The nine District Advisory Councils (DAC) are as follows:
