Diagnosed Diabetes in the US since 1958

The graph below is impressive.

It would be nice to have an estimate of what the graph would look like for diagnosed and undiagnosed diabetes under constant diagnostic criteria.  James Smith claims that

the prevalence of diagnosed diabetes among adult men has more than doubled over the past twenty-five years, from 3 percent of the population in the late 1970s to 7 percent today. The prevalence of actual diabetes (including both diagnosed and undiagnosed cases) has also risen, though less dramatically - from 6 percent of the population to 9 percent today, a fifty percent increase.

No time to get behind the NBER paywall to pull the paper now...
