== 21st century ==
During the beginning of the 21st century, many cities in the South and West experienced significant growth in terms of population. This was trend that continued from the late 20th century where a lot of growth occurred in cities in the Sunbelt region. Texas in particular has experienced a tremendous amount of growth in the 21st century so far as the state with the largest population jump, with cities like Austin, San Antonio, Dallas, Fort Worth, Houston, and many of their suburbs constantly being ranked as the fastest-growing cities in the country. Other cities in the South that have experienced significant population growth recently include Atlanta, Washington, Tampa, Orlando, Miami, Nashville, Charlotte, and Raleigh. Western cities have experienced lots of growth as well, with cities like Seattle, Phoenix, Riverside, Denver, Portland, and Las Vegas seeing a great influx of new residents. Smaller cities in the Southern and Western states have seen a large amount of population growth too, including Charleston, Myrtle Beach, Savannah, Cape Coral, Sarasota, Ogden, Colorado Springs, Boise, and more. There are exceptions in the Southern and Western states though to this trend of cities having a large influx of new residents with places like Los Angeles, Memphis, Albuquerque, and Birmingham experiencing a slow growth in population, especially compared to other nearby areas. Some areas in the South and West have even seen population loss including Montgomery, Jackson, and parts of the San Francisco Bay Area like Marin County. The San Francisco area, while overall still experiencing a decent population growth rate, has areas experiencing little to no growth and has more residents leaving than any other U.S. city due to the high cost of living in the region. Meanwhile, cities in the Rust Belt, such as Detroit, Cleveland, St. Louis, Buffalo, Pittsburgh, and Chicago, have experienced negative or stagnant growth in terms of population too. Many people from these locations are moving to the booming cities in the Southern and Western states. Starting in the late 20th century and continuing into the 21st century, many cities across the country began creating new public transportation systems. After many public transportation systems, such as streetcars, were scrapped in cities starting in the 1950s, the automobile dominated America's urban transportation network. However, many cities, especially in the 21st century, have started creating new, rebuilding, or expanding public transportation systems to help combat problems like traffic congestion and air pollution from all of the commuting vehicles. Many cities have added new light rail systems, such as Phoenix's Valley Metro Rail or Charlotte's Lynx Blue Line. Other cities have heavily expanded their already existing transportation networks with new lines, such as the Expo Line that opened in 2012 in Los Angeles. Modern streetcars have been built in various cities across America recently as well, including the Atlanta Streetcar and the Dallas Streetcar. Some cities though have rebuilt their heritage streetcars in the 21st century, such as Tampa with its TECO Line Streetcar that opened in 2002. New commuter rail systems have been built in a bunch of cities too like Orlando's Sunrail or Seattle's Sounder Commuter Rail. Overall though, public transportation has been an important issue for 21st century American cities, and as a result there has been a large amount of focus on building or expanding various public transportation systems within urban areas.
