An internal survey by the retailer reveals the number of uninsured employees has dropped to 7.3%

Wal-Mart said on Tuesday that the number of uninsured associates decreased by more than 20 %, compared to one year ago.

Linda Dillman, executive vice president of benefits and risk management for Wal-Mart, said this was due, in part, to changes to the company’s benefits package.

According to data collected in an internal survey the percentage of associates who reported having no coverage declined from 9.6 % to 7.3 %.

The retailer, which has been the target of union-led criticism over its healthcare benefits package, said more than 1.1m people were now covered by its plans.

“While the number of uninsured Wal-Mart associates is less than half of the national average, it is still too high. Our goal is to have every eligible associate select health care coverage.
