Government and politics Government The Government of Pittsburgh is composed of the Mayor of Pittsburgh, the Pittsburgh City Council, and various boards and commissions. The mayor and the nine-member council each serve four-year terms. Since the 1950s the Mayor's Chief of Staff has assumed a large role in advising, long term planning, and as a "gatekeeper" to the mayor. City council members are chosen by plurality elections in each of nine districts. The government's official offices are in the Pittsburgh City-County Building. The Pennsylvania Supreme Court holds sessions in Pittsburgh, as well as Harrisburg and Philadelphia. Pittsburgh is represented in the Pennsylvania General Assembly by three Senate Districts and nine House Districts. Federally, Pittsburgh is part of Pennsylvania's 12th congressional district. Politics In 2006, Council President Luke Ravenstahl was sworn in as mayor at age 26, becoming the youngest mayor in the history of any major American city. His successor, Bill Peduto, was sworn in on January 6, 2014. In November 2021, Pittsburgh elected its first African-American mayor, Ed Gainey. Prior to the American Civil War, Pittsburgh was strongly abolitionist. It is considered the birthplace of the national Republican Party, as the party held its first convention here in February 1856. From the Civil War to the 1930s, Pittsburgh was a Republican stronghold. The effects of the Great Depression, combined with entrenched local GOP scandals, resulted in a shift among voters to the Democratic Party. With the exceptions of the 1973 and 1977 elections (where lifelong Democrats ran off the party ticket), Democrats have been elected consecutively to the mayor's office since the 1933 election. The city's ratio of party registration is 5 to 1 Democrat. Pittsburgh is represented in the Pennsylvania General Assembly by three Senate Districts (Lindsey Williams (D)-38, Wayne D. Fontana (D)-42, and Jay Costa (D)-43) and nine House Districts (Aerion Abney-19, Adam Ravenstahl-20, Sara Innamorato-21, Dan Frankel-23, Martell Covington-24, Dan Deasy-27, Summer Lee-34, and Harry Readshaw-36, Dan Miller-42). Federally, Pittsburgh is part of Pennsylvania's 12th congressional district, represented by Democrat Summer Lee since 2023 and also by Democrat Chris Deluzio. Law enforcement The area's largest law enforcement agency is the Pittsburgh Bureau of Police, with close to 850 sworn officers. The city also has separate housing and school
