Malls are dwindling in number, with many struggling properties reduced to largely vacant shells.

With their maze of walkways and fast-food courts, malls have long been an iconic, if sometimes unsightly, presence in the American retail landscape. A few were made famous by their sheer size, others for the range of shopping and social diversions they provided.

But the long recession is helping to empty out the promenades. Some analysts estimate that the number of so-called "dead malls" -- centers debilitated by anemic sales and high vacancy rates -- will swell to more than 100 by the end of this year.

In the 12 months ended 31 March, US malls collectively posted a 6.5% decline in tenants' same-store sales, according to Green Street Advisors Inc., a real-estate research firm. The recent slump was led by an average 7.3% sales drop at Simon Property Group, the operator with the largest number of mall locations.
