to provide nationally representative data
CDC says NVDRS data are not nationally representative. The system expanded gradually by state, and CDC explicitly warns users not to treat its data as a complete national picture.
Full reasoning
The article says the National Violent Death Reporting System (NVDRS) is used "to provide nationally representative data," but CDC says the opposite.
On CDC's official NVDRS State Profiles page, CDC states: "NVDRS data are not nationally representative. We do not yet have a complete picture of violent death across the nation." CDC explains that NVDRS began with only a small number of participating states and expanded over time, which is why the data should not be described as nationally representative.
That directly contradicts the article's wording. A more accurate description would be that NVDRS is a state-based violent-death surveillance system whose coverage expanded over time and whose data have historically not been nationally representative.

NVDRS was created in 2002 and began collecting data from six states... However, keep in mind that NVDRS data are not nationally representative. We do not yet have a complete picture of violent death across the nation.
