Dollar General now has roughly 18,800 stores in the U.S., compared with 5,000 in 2001.
Dollar stores, boosted by demand for less expensive groceries and goods in underserved rural areas, are far outpacing other retailers in opening new stores.
Bricks-and-mortar shopping has rebounded strongly since the height of the pandemic, with many companies now adding new locations.
Leading the pack are the two largest U.S. dollar-store chains, Dollar General Corp. and Dollar Tree Inc., which combined expect to have opened more than 1,300 net new stores by the end of the fiscal year that ends in late January, according to the companies.
