Chicago Map

• Chicago is the county seat of Cook County. The government of the City of Chicago is divided into executive and legislative branches. The Mayor of Chicago is the chief executive, elected by general election for a term of four years, with no term limits. The mayor appoints commissioners and other officials who oversee the various departments. In addition to the mayor, Chicago's two other citywide elected officials are the clerk and the treasurer.

• The City Council is the legislative branch and is made up of 50 aldermen, one elected from each ward in the city. The council enacts local ordinances and approves the city budget. Government priorities and activities are established in a budget ordinance usually adopted each November. The council takes official action through the passage of ordinances and resolutions.

• During much of the last half of the 19th century, Chicago's politics were dominated by a growing Democratic Party organization dominated by ethnic ward-heelers. During the 1880s and 1890s, Chicago had a powerful radical tradition with large and highly organized socialist, anarchist and labor organizations. For much of the 20th century, Chicago has been among the largest and most reliable Democratic strongholds in the United States, with Chicago's Democratic vote the state of Illinois has been "solid blue" in presidential elections since 1992. The citizens of Chicago have not elected a Republican mayor since 1927, when William Thompson was voted into office. The strength of the party in the city is partly a consequence of Illinois state politics, where the Republicans have come to represent the rural and farm concerns while the Democrats support urban issues such as Chicago's public school funding. Chicago contains close to 25% of the state's population, and as such, eight of Illinois' 19 U.S. Representatives have part of Chicago in their districts.

• Former Chicago Mayor Richard J. Daley's mastery of machine politics preserved the Chicago Democratic Machine long after the demise of similar machines in other large U.S. cities. During much of that time, the city administration found opposition mainly from a liberal "independent" faction of the Democratic Party. The independents finally gained control of city government in 1983 with the election of Harold Washington. From 1989 until May 16, 2011, Chicago was under the leadership of Richard M. Daley, the son of Richard J. Daley. Because of the dominance of the Democratic Party in Chicago, the Democratic primary vote held in the spring is generally more significant than the general elections in November for U S House and Illinois State seats. The aldermanic, mayoral, and other city offices are filled through nonpartisan elections with runoffs if needed. On May 16, 2011, Rahm Emanuel was sworn in as the 55th mayor of Chicago, ending a 22-year era led by Richard M. Daley.

• When Chicago was incorporated in 1837, it chose the motto Urbs in Horto, a Latin phrase which translates into English as "City in a Garden". Today, the Chicago Park District consists of 552 parks with over 7,300 acres (3,000 ha) of municipal parkland. There are 33 sand Chicago beaches, a plethora of museums, two world-class conservatories, 16 historic lagoons, and 10 bird and wildlife gardens. Lincoln Park, the largest of the city's parks, covers 1,200 acres (490 ha) and has over 20 million visitors each year, making it second only to Central Park in New York City in number of visitors. With berths for more than 5,000 boats, the Chicago Park District operates the nation's largest municipal harbor system; even larger than systems in cities such as New York City, Los Angeles, or Miami. In addition to ongoing beautification and renewal projects for the existing parks, a number of new parks have been added in recent years, such as the Ping Tom Memorial Park in Chinatown, DuSable Park on the Near North Side, and most notably, Millennium Park in a section of one of Chicago's oldest parks, Grant Park in the Chicago Loop.

• The wealth of greenspace afforded by Chicago's parks is further augmented by the Cook County Forest Preserves, a network of open spaces containing forest, prairie, wetland, streams, and lakes that are set aside as natural areas which lie along the city's periphery, home to both the Chicago Botanic Garden in Glencoe and the Brookfield Zoo in Brookfield.

• Chicago literature found its roots in the city's tradition of lucid, direct journalism, lending to a strong tradition of social realism. Consequently, most notable Chicago fiction focuses on the city itself, with social criticism keeping exultation in check. Writers such as Mike Royko, Studs Terkel, Stuart Dybek, Carl Sandburg, James T. Farrell, Upton Sinclair, Saul Bellow, John Guzlowski, Sandra Cisneros Nelson Algren and Finley Peter Dunne have all drawn the city's literary portrait in diverse ways, united by the fact that their observations brought the world's attention to focus on Chicago.

• The city lies within the humid continental climate zone, and experiences four distinct seasons. Summers are hot and humid, with a July daily average of 84.7 °F (29.3 °C). In a normal summer temperatures exceed 90 °F (32 °C) on 21 days. Winters are cold, snowy, and windy, with some sunny days, and with a January average of 23.5 °F (−4.7 °C). Temperatures often (43 days) stay below freezing for an entire day, and subzero lows occur on eight nights per year. Spring and fall are mild seasons with low humidity.

• According to the National Weather Service, Chicago's highest official temperature reading of 107 °F (42 °C) was recorded on June 1, 1934 and July 11, 1936, both at Midway Airport. The lowest temperature of −27 °F (−33 °C) was recorded on January 20, 1985, at O'Hare Airport. The city can experience extreme winter cold spells that may last for several consecutive days.

• In 2008, Chicago attracted 32.4 million domestic leisure travelers, 11.7 million domestic business travelers and 1.3 million overseas visitors. These visitors contributed more than US$11.8 billion to Chicago's economy. Upscale shopping along the Magnificent Mile and State Street, thousands of restaurants, as well as Chicago's eminent architecture, continue to draw tourists. The city is the United States' third-largest convention destination. Most conventions are held at McCormick Place, just south of Soldier Field. The historic Chicago Cultural Center (1897), originally serving as the Chicago Public Library, now houses the city's Visitor Information Center, galleries and exhibit halls. The ceiling of its Preston Bradley Hall includes a 38 ft (12 m) Tiffany glass dome. Grant Park holds Millennium Park, Buckingham Fountain (1927), and the Art Institute of Chicago. The park also hosts the annual Taste of Chicago festival. In Millennium Park, there is the reflective Cloud Gate sculpture. Also, an outdoor restaurant transforms into an ice rink in the winter season. Two tall glass sculptures make up the Crown Fountain. The fountain's two towers display visual effects from LED images of Chicagoans' faces, along with water spouting from their lips. Frank Gehry's detailed, stainless steel band shell, the Jay Pritzker Pavilion, hosts the classical Grant Park Music Festival concert series. Behind the pavilion's stage is the Harris Theater for Music and Dance, an indoor venue for mid-sized performing arts companies, including the Chicago Opera Theater and Music of the Baroque.

• Navy Pier, located just east of Streeterville, is 3,000 ft (910 m) long and houses retail stores, restaurants, museums, exhibition halls and auditoriums. Its 150-foot (46 m) tall Ferris wheel is one of the most visited landmarks in the Midwest, attracting about 8 million people annually.

• In 1998, the city officially opened the Museum Campus, a 10-acre (4.0 ha) lakefront park, surrounding three of the city's main museums, each of which is of national importance: the Adler Planetarium & Astronomy Museum, the Field Museum of Natural History, and the Shedd Aquarium. The Museum Campus joins the southern section of Grant Park, which includes the renowned Art Institute of Chicago. Buckingham Fountain anchors the downtown park along the lakefront. The University of Chicago Oriental Institute has an extensive collection of ancient Egyptian and Near Eastern archaeological artifacts. Other museums and galleries in Chicago include the Chicago History Museum, the DuSable Museum of African American History, the Museum of Contemporary Art, the Peggy Notebaert Nature Museum, the Polish Museum of America, the Museum of Broadcast Communications and the Museum of Science and Industry.

• The top activity while visitors tour Chicago for leisure is entertainment, approximately 33% of all leisure travelers. Facilities such as McCormick Place and the Chicago Theatre contribute to this percentage.
