What are the limits of these Dental Hygienist salary numbers?

BLS OES is an employer survey of W-2 wages — it excludes contractor pay, bonuses outside the base wage definition, equity compensation, and tip income. Self-employed practitioners and gig workers are not represented. For occupations with significant non-W-2 income, the BLS figure is a floor, not a complete picture.

Why is the BLS dental hygienist median hourly so much higher than annual implies in South Dakota?

Many dental hygienists in South Dakota work 32 hours/week or fewer — the four-day-a-week schedule is the industry norm. BLS OEWS reports annualized W-2 wages, so hygienists working 0.7-0.8 FTE pull the annual median below what the hourly rate would suggest. The BLS-reported hourly figure on the underlying release is the cleaner per-hour comparison; the annual median understates earning power per worked hour by 20-30% in most South Dakota markets.
