The Municipality of Princeton is a borough in Mercer County, in the U.S. state of New Jersey. It was established on January 1, 2013, through the consolidation of the Borough of Princeton and Princeton Township, both of which are now defunct. As of the 2020 United States census, the borough's population was 30,681,

Princeton was founded before the American Revolutionary War. The borough is the home of Princeton University, one of the world's most acclaimed research universities, which bears its name and moved to the community in 1756 from the educational institution's previous location in Newark. Although its association with the university is primarily what makes Princeton a college town, other important institutions in the area include the Institute for Advanced Study, Princeton Plasma Physics Laboratory, Princeton Theological Seminary, Opinion Research Corporation, Bristol-Myers Squibb, Siemens Corporate Research, SRI International, FMC Corporation, Educational Testing Service, the Robert Wood Johnson Foundation, Amrep, Church and Dwight, Berlitz International, and Dow Jones & Company.

Princeton is roughly equidistant from New York City and Philadelphia. It is close to many major highways that serve both cities (e.g., Interstate 95 and U.S. Route 1), and receives major television and radio broadcasts from each. It is also close to Trenton, New Jersey's capital city, New Brunswick and Edison.

The New Jersey governor's official residence has been in Princeton since 1945, when Morven (in what was then Princeton Borough) became the first governor's mansion. In 1982, it was replaced by the larger Drumthwacket, a colonial mansion located in the former township, but not all have actually lived in these houses. Morven became a museum and garden, owned and operated by the New Jersey Historical Society.

Throughout much of its history, the community was split into two separate municipalities: a township and a borough. The central borough was completely surrounded by the township. The borough seceded from the township in 1894 in a dispute over school taxes; the two municipalities later formed Princeton Public Schools, and some other public services were conducted together before they were reunited into a single Princeton in January 2013. Princeton Borough contained Nassau Street, the main commercial street, most of the university campus, and incorporated most of the urban area until the postwar suburbanization. The borough and township had roughly equal populations. Other major streets include Harrison, Witherspoon, Nassau, Bayard, Washington, and Stockton.

The Lenape Native Americans were the earliest identifiable inhabitants of the Princeton area.

Europeans settled into the area in the late part of the 17th century, arriving from Delaware to settle West Jersey, and from New York to settle East Jersey, with the site destined to become Princeton being amid the wilderness between these two boroughs. The first European to find his home in the boundaries of the future municipality was Henry Greenland. He built his house in 1683 along with a tavern, where representatives of West and East Jersey met to set the boundaries between the two provinces. Greenland's son-in-law Daniel Brimson inhabited the area by 1690, and left property in a will dated 1696. Nathaniel Fitz Randolph, a native of the town, attested in his private journal on December 28, 1758, that Princeton was named in 1724 upon the making/construction of the first house in the area by James Leonard, The community was later known by a variety of names, including: Princetown, Prince's Town and finally Princeton. The name Princeton was first used in 1724 and became common within the subsequent decade. Another theory suggests that the name came from a large land-owner named Henry Prince, the son-in-law of a well-known English merchant, but no evidence backs this contention. The numbers have become stagnant; since the arrival of the College of New Jersey, now Princeton University, in 1756, the town's population spikes every year during the fall and winter and drops significantly over the course of the summer. The house has kept its original staircase, flooring and paneled walls. Around 70% of the house has been unaltered. Aside from safety features such as wheelchair access and electrical work, the house has been restored to its original appearance and character.

Government history

During the most stirring events in its history, Princeton was a wide spot in the road; the boundary between Somerset County and Middlesex County ran right through Princeton, along the high road between New York and Philadelphia, now Nassau Street. When Mercer County was formed in 1838, part of West Windsor was added to the portion of Montgomery Township which was included in the new county, and made into Princeton Township; the area between the southern boundary of the former Borough and the Delaware and Raritan Canal was added to Princeton Township in 1853. Princeton Borough became a separate municipality in 1894. See the section on "government and politics" for more details about the 2011 merger of borough and township.

Geography

Princeton is located just south of a long, curving ridge known as Princeton Ridge. As Princeton is in a low-lying area, there have been issues with cell phone signals.

According to the U.S. Census Bureau, Princeton had a total area of 18.41 square miles (47.69&nbsp;km<sup>2</sup>), including 17.95 square miles (46.48&nbsp;km<sup>2</sup>) of land and 0.47 square miles (1.21&nbsp;km<sup>2</sup>) of water (2.53%). Port Mercer, Princeton Basin, and Jugtown are unincorporated communities that have been absorbed into Greater Princeton over the years, but still maintain their own community identity.

Princeton borders the municipalities of Hopewell Township, Lawrence Township, and West Windsor in Mercer County; Plainsboro Township and South Brunswick Township in Middlesex County; and Franklin Township and Montgomery Township in Somerset County.

ZIP codes for Princeton include 08540, 08541 (Educational Testing Service), 08542 (largely the old Borough), 08543 (PO boxes), and 08544 (the University).

Government

Local government

Princeton is governed under the borough form of New Jersey municipal government, which is used in 218 municipalities (of the 564) statewide, making it the most common form of government in New Jersey. The governing body is comprised of the mayor and the borough council, with all positions elected at-large on a partisan basis as part of the November general election. The mayor is elected directly by the voters to a four-year term of office. The borough council includes six members elected to serve three-year terms on a staggered basis, with two seats coming up for election each year in a three-year cycle. The borough form of government used by Princeton is a "weak mayor / strong council" government in which council members act as the legislative body with the mayor presiding at meetings and voting only in the event of a tie. The mayor can veto ordinances subject to an override by a two-thirds majority vote of the council. The mayor makes committee and liaison assignments for council members, and most appointments are made by the mayor with the advice and consent of the council.

The mayor is elected directly by the voters to a four-year term of office, serves as Princeton's chief executive officer and nominates appointees to various boards and commissions subject to approval of the council. The mayor presides at council meetings and votes in the case of a tie or a few other specific cases. Members of the Princeton Council are Council President Mia Sacks (D, 2026), David F. Cohen (D, 2027), Leticia Fraga (D, 2027), Michelle Pirone Lambros (D, 2026), Leighton Newlin (D, 2027) and Brian McDonald (D, 2027).

In 2018, Princeton had an average property tax bill of $19,388, the highest in the county, compared to an average bill of $8,767 statewide.

Merger of borough and township

People in the township tried unsuccessfully to merge borough and township in a struggle that lasted nearly fifty years. The first failed attempt to consolidate borough and township was made in 1953, with 63% of township voters in favor of a merger and 57% of borough voters opposed. Subsequent attempts were voted down by borough residents, in large part due to different zoning needs of the densely populated borough versus the more widely spaced properties of the township (surrounding the borough). An attempt to consolidate in 1979 passed with 70% support in the township but failed in the borough by 33 votes, a result that was upheld after a recount. Although township voters again supported a 1996 merger referendum by an almost 3–1 margin, about 57% of borough voters rejected the consolidation proposal, marking the sixth such failure.

The residents of both the Borough of Princeton and the Township of Princeton voted on November 8, 2011, to merge the two municipalities into one. This was the first referendum when university student voters were encouraged and allowed to register to vote locally, and that likely contributed strongly to the measure passing, as the students were not home owners concerned with zoning matters, and they all counted as part of the borough and not the township. In Princeton Borough, 1,385 voted for and 902 voted against, while in Princeton Township 3,542 voted for and 604 voted against. Proponents of the merger asserted that when the merger is completed the new Municipality of Princeton would save $3.2 million as a result of some scaled down services including layoffs of 15 government workers including 9 police officers (however the measure itself does not mandate such layoffs). Opponents of the measure challenged the findings of a report citing a cost savings as unsubstantiated, expressed concerns about differing zoning needs between borough and township, and noted that voter representation would be reduced in a smaller government structure. The merger was the first in the state since 1997, when Pahaquarry Township voted to consolidate with Hardwick Township The consolidation took effect on January 1, 2013.

Federal, state and county representation
