• Moderately concentrated

  Top three sectors employ 58% 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 (Financial activities, $187,306/yr) pays 4.6× the lowest (Leisure & hospitality, $40,439/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 8.4 workers, a small-business-dominated local economy. Expect more self-employed and small-business-owner panelists than in institutional-employer venues.
