 According to a September 2002 survey by the state of Georgia, one in four children of Walmart employees were enrolled in PeachCare for Kids, the state's health-insurance program for uninsured children, compared to the state's second-biggest employer, Publix, which had one child in the program for every 22 children of employees.A December 2004 nationwide survey commissioned by Walmart showed that the use of public-assistance health-care programs by children of Walmart workers was at a similar rate to other retailers' employees, and at rates similar to the United States population as a whole.As of October 2005, Walmart's health insurance covered 44% or approximately 572,000 of its 1.3 million United States workers.
