• Moderately concentrated

  Top three sectors employ 56% of the county workforce. Substantial intra-sector overlap among panelists is likely; confirm employer relationships before sector-specific framing.

• Wide wage spread

  Highest-paid sector (Natural resources & mining, $88,566/yr) pays 4.2× the lowest (Leisure & hospitality, $21,021/yr). Stark intra-economy class divisions on the panel; calibrate damages and lost-wages framing to that range.

• Small-business scale

  Average establishment employs only 5.5 workers, a small-business-dominated local economy. Expect more self-employed and small-business-owner panelists than in institutional-employer venues.
