Walmart became the world’s largest private employer after acquiring the Mexican chain Cifra.
Walmart entered Mexico through a joint venture with Cifra in 1991 and later acquired control of the business. The Mexican operation became part of Walmart’s international expansion, which has included stores and e-commerce activities in multiple countries.
The company was founded by Sam Walton, who opened the first Walmart store in Rogers, Arkansas, in 1962. Its retail model emphasized low prices, high sales volume, centralized purchasing, and efficient distribution.
Employer rankings can vary depending on whether governments, contractors, franchise workers, or subsidiaries are counted. Walmart is commonly described as the world’s largest private employer, while the precise ranking and employee total can change over time.
