The population peaked at more than two million residents in 1950, then began to decline with the restructuring of industry, which led to the loss of many middle-class union jobs. In addition, suburbanization had enticed many of the more affluent residents to outlying railroad commuting towns and newer housing. The resulting reduction in Philadelphia's tax base and the resources of local government caused the city to struggle through a long period of adjustment, with it approaching bankruptcy by the late 1980s. Revitalization and gentrification of neighborhoods began in the late 1970s and continues into the 21st century, with much of the development occurring in the Center City and University City neighborhoods, while simultaneously exacerbating a shortage of affordable housing in Philadelphia. After many of the old manufacturers and businesses left Philadelphia or shut down, the city started attracting service businesses and began to market itself more aggressively as a tourist destination. Contemporary glass-and-granite skyscrapers were built in Center City beginning in the 1980s. Historic areas such as

and Society Hill were renovated during the reformist mayoral era of the 1950s through the 1980s, making those areas among the most desirable neighborhoods in Center City. Many immigrants from around the world began to enter the U.S. through Philadelphia as their gateway. These developments led to a reversal of the city's population decline between 1950 and 2000, during which it lost about 25 percent of its residents.

Philadelphia eventually began experiencing a growth in its population in 2007, which continued with gradual yearly increases through the present. Although Philadelphia is rapidly undergoing gentrification, the city maintains strategies to minimize displacement of homeowners in gentrifying neighborhoods.

Cityscape

City planning

Philadelphia's central city was created in the 17th century following the plan by William Penn's surveyor Thomas Holme. Center City is structured with long, straight streets running nearly due east–west and north–south, forming a grid pattern between the

and Schuylkill rivers that is aligned with their courses. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire. In keeping with the idea of a "Greene Countrie Towne", and inspired by the many types of trees that grew in the region, Penn named many of the east–west streets for local trees. Penn planned the creation of five public parks in the city which were renamed in 1824 (new names in parentheses): Centre Square (Penn Square), Northeast Square ( Franklin Square), Southeast Square ( Washington Square), Southwest Square ( Rittenhouse Square), and Northwest Square ( Logan Circle/Square). Center City had an estimated 183,240 residents , making it the second-most populated downtown area in the United States, after

While newer homes have been built recently, much of the housing dates to the 18th, 19th and early 20th centuries, which has created problems such as urban decay and vacant lots. Some neighborhoods, including Northern Liberties and Society Hill, have been rehabilitated through gentrification.

Air quality

Philadelphia County received an ozone grade of F and a 24-hour particle pollution rating of D in the American Lung Association's 2017 State of the Air report, which analyzed data from 2013 to 2015. The city was ranked 22nd for ozone, 20th for short-term particle pollution, and 11th for year-round particle pollution.

Immigration and cultural diversity
