    Born in the 1950s, shopping malls were once the symbol of the U.S. consumer culture, but many are now dying out.

Dying shopping malls can be found across the United States, often in middle-class suburbs. Economic decline in certain areas together with an upward trend towards online shopping and new forms of urban shopping centers have pushed the once seemingly unbeatable shopping malls into decline. It is estimated that 15 to 50 percent of shopping malls may close in the coming decades.

American shopping culture follows its housing culture. Numerous shopping malls were therefore born after the Second World War, as Americans with cars and fat wallets moved to the suburbs. U.S. shopping malls were built at a rapid pace as shoppers fled cities, peaking in the mid-1990s when they were being built at a rate of 140 a year. Thus, too many shopping malls are left though construction has gradually decreased since then.

Currently, there are around 1,500 shopping malls across the U.S. Most share a handful of similar feature. They usually contain two or three stories of stores separated by walkways. Food courts serve pizza and other fast food. Parking lots are big enough to easily misplace a car.

Shopping malls in Europe might contain grocery stores or childcare centers, while those in Japan are often built around mass transit (交通枢纽). But the suburban American shopping malls are hard to get to and mainly sell clothes and gifts.

As many shopping malls became redundant (过剩的), leaders in many U.S. towns who once fought for malls now struggle with how to transform them to new uses. Highland Mall in Texas is being transformed into a community college campus, and Lakeland Mall in Florida now houses a megachurch (大型教会). Others have been redeveloped to include housing, offices and even green space. However, it is hard to imagine every shopping mall meeting the demands for such transformations.
