The state of Pennsylvania has 50 state Senate districts. Each district elects one senator.
Use the interactive map below to find your district.
In Pennsylvania, the statutory authority to draw congressional district boundaries is vested with the Pennsylvania General Assembly. These lines are subject to gubernatorial veto.[15]
State legislative district lines are drawn by a politician commission. Established in 1968, the commission comprises five members:[15]
The Pennsylvania Constitution requires that state legislative districts be contiguous and compact. Further, state legislative districts should "respect county, city, incorporated town, borough, township and ward boundaries." There are no such requirements in place for congressional districts.[15]
On February 4, 2022, the Pennsylvania Legislative Reapportionment Commission voted 4-1 to approve new state House and Senate maps.[16] House Majority Leader Kerry Benninghoff (R) voted no, while Senate Majority Leader Kim Ward (R), state Rep. Joanna McClinton (D), state Sen. Jay Costa (D), and chairman Mark Nordenberg voted yes.[16] These maps took effect for Pennsylvania's 2022 legislative elections.

Pennsylvania received its local census data on March 9, 2011. The state had a 3.4 percent growth rate from 2000-2010, which was below the national average of 9.7 percent. The five most populous cities in the state did not follow a trend: Philadelphia grew by 0.6 percent, Pittsburgh decreased by 8.6 percent, Allentown grew by 10.7 percent, Erie decreased by 1.9 percent, and Reading grew by 8.5 percent. The county with the largest rate of growth was Forest County with a 56 percent rate of growth.[17]
On August 17, 2011, the Commission approved the census data and went to work on a preliminary map, which it passed on October 31, 2011, by a 3-2 vote. Final maps were approved on December 12, 2011, by a 4-1 vote. There was a 30-day window to file appeals, during which 11 were filed. The state Supreme Court overturned the maps on January 25, 2012.
The commission met on April 12, 2012, to vote in favor of a compromise map, which contained two Senate district splits, and 68 House district splits. On June 8, the commission approved the final plan, which went to the state Supreme Court for final approval.

Other issues included economic development, public pension reform, liquor privatization, and child abuse.[31] In November 2013, the Pennsylvania state House and state Senate voted unanimously on a bill, which was signed by Gov. Tom Corbett (R), to change the state’s unemployment compensation law. The bill closed a loophole that allowed a state employee to retire from his job and begin collecting benefits, only to be hired back as a part-time employee while also collecting unemployment compensation after leaving a previous job. While the law closed a triple-dipping loophole, the changes did not prevent double-dipping, in which a state employee retires, begins collecting pension benefits, and returns to work a part-time position.[32] 2012[edit]

The Tenth Amendment of the U.S. Constitution declares that any power not already given to the federal government is reserved to the states and the people.[35] State governments across the country use this authority to hold legislative sessions where a state's elected representatives meet for a period of time to draft and vote on legislation and set state policies on issues such as taxation, education, and government spending. The different types of legislation passed by a legislature may include resolutions, legislatively referred constitutional amendments, and bills that become law.
Article II of the Pennsylvania Constitution establishes when the Pennsylvania General Assembly, of which the Senate is a part, is to meet. Section 4 of Article II states that the General Assembly is to convene its regular session on the first Tuesday of January each year.
Section 4 gives the Governor of Pennsylvania the authority to convene special sessions of the General Assembly either when he judges a special session to be in the public interest, or when a majority of each legislative House requests a special session.
Every state legislature throughout the country features its own internal procedures that it uses to govern itself and how it interacts with other parts of state government. Ballotpedia's coverage of internal state legislative procedures includes veto overrides, the role of the legislature in the state budget, and procedures for filling membership vacancies.
State legislatures can override governors' vetoes. Depending on the state, this can be done during the regular legislative session, in a special session following the adjournment of the regular session, or during the next legislative session. The rules for legislative overrides of gubernatorial vetoes in Pennsylvania are listed below.
How many legislators are required to vote for an override? Two-thirds of members in both chambers.
| Two-thirds of members in both chambers must vote to override a veto, which is 136 of the 203 members in the Pennsylvania House of Representatives and 34 of the 50 members in the Pennsylvania State Senate. Pennsylvania is one of 36 states that requires a two-thirds vote from both of its legislative chambers to override a veto. |
How can vetoes be overridden after the legislature has adjourned?
| Vetoes can be overridden when the next regular session convenes, provided that an election has not occurred.[36] |
Authority: Article IV, Section 15 of the Pennsylvania Constitution.
| "Every bill which shall have passed both Houses shall be presented to the Governor; if he approves he shall sign it, but if he shall not approve he shall return it with his objections to the House in which it shall have originated, which House shall enter the objections at large upon their journal, and proceed to re-consider it. If after such re-consideration, two-thirds of all the members elected to that House shall agree to pass the bill, it shall be sent with the objections to the other House by which likewise it shall be re-considered, and if approved by two-thirds of all the members elected to that House it shall be a law; but in such cases the votes of both Houses shall be determined by yeas and nays, and the names of the members voting for and against the bill shall be entered on the journals of each House, respectively." |
| Pennsylvania on |
The state operates on an annual budget cycle. The sequence of key events in the budget process is as follows:[37]
Pennsylvania is one of 44 states in which the governor has line item veto authority.[37][38]
The governor is legally required to submit a balanced budget proposal. Likewise, the legislature is required to pass a balanced budget.[37]
Every state legislature and state legislative chamber in the country contains several legislative committees. These committees are responsible for studying, amending, and voting on legislation before it reaches the floor of a chamber for a full vote. The different types of committees include standing committees, select or special, and joint.
Ballotpedia covers standing and joint committees. The Pennsylvania State Senate has 23 standing committees:
In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.
The methods in which the Pennsylvania Constitution can be amended:
The Pennsylvania Constitution provides for one mechanism for amending the state's constitution—a legislative process. However, the state constitution does not mention a constitutional convention process, and the legislature has called constitutional conventions in the past. Pennsylvania requires a simple majority vote (50% plus 1) for voters to approve constitutional amendments.
In Pennsylvania, citizens do not have the power to initiate ballot measures at the state level.
According to Article XI, the state Legislature can refer constitutional amendments to the ballot for voters to decide. A simple majority vote is required during two successive legislative sessions for the Pennsylvania State Legislature to place a constitutional amendment on the ballot. That amounts to a minimum of 102 votes in the Pennsylvania House of Representatives and 26 votes in the Pennsylvania State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.
When the Legislature finds that a "major emergency threatens or is about to threaten the Commonwealth," a constitutional amendment can be referred to the ballot with a two-thirds vote during one legislative session.
