ST. PAUL (AP) - A new audit shows there's more work to be done to  diversify Minnesota's hiring, purchasing and contracting practices.

The audit found the state historically has had strong policies to promote equal opportunities for minorities and other targeted groups. But, underfunding,  inadequate staffing and insufficient data are impeding those efforts.

In 2015, about 3 percent of the roughly $2 billion the state awarded in contracts went to businesses owned by someone from a targeted group. The majority of that 3 percent went to businesses owned by women, leaving the rest to business owners of color.

The audit was proposed by state and local chapters of the NAACP and backed last year by Gov. Mark Dayton.
