America's brick and mortar continue to struggle as an estimated 12,000 retail stores could close by the end of 2019.

But if the carnage in the United States' retail landscape seemed bad last year, it pales in comparison to the damage it is suffering these days.

There have already been 20% more store shutdowns announced this year than in the fall of 2018, according to a new report from global marketing research agency Coresight Research.

More than 7,400 shops are expected to shut down in the coming months, according to Coresight, with thousands of locations already leaving the business.

Last year, 5,864 stores shut down, and 3,258 opened. Beyond the glass and glitter adorning main avenues across the U.S., the collateral damage in terms of employment lost is another story.

For instance, Challenger, Gray & Christmas had to let go of 53,248 workers through June, compared to 98,563 for all of last year. And that is just one side of the coin.

Footwear company Payless ShoeSource, which recently filed for bankruptcy and closed its remaining U.S. stores in late June this year, accounts for an estimated 37% of the total shutdown.

Internal bleeding

Coresight said the square footage of retail space per person in the U.S. exceeds those in comparable Western economies, with 23.5 square feet of retail space a person here, compared to 11.1 square feet of retail space per person in Australia, and 16.4 square feet per person in Canada.
