It is important to understand that Dollar General and Family Dollar serve thousands of flyover communities where there are no Walmart stores or other viable market access. Dollar General has stated that it can generate profits in communities with fewer than 1,000 homes. Walmart generally requires a much larger population base for its stores.
Dollar General is the largest retailer in the US by number of locations, with over 20,000 stores across 48 states. Family Dollar operates over 8,200 stores. Walmart's U.S. store count is significantly smaller (around 4,700 U.S. Walmart stores and 600 Sam's Clubs as of 2024).
Dollar stores are frequently found at the heart of "food deserts," which are often rural communities located more than 10 miles from a grocery store selling fresh produce—a gap often created when a community is too small to maintain a supermarket or attract a retailer like Walmart.
