• 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.

• Moderate wage spread

  Highest-paid sector (Financial activities, $109,610/yr) pays 2.7× the lowest (Leisure & hospitality, $40,752/yr). Expect meaningful income variation across the panel.

• Small-business scale

  Average establishment employs only 9.5 workers, a small-business-dominated local economy. Expect more self-employed and small-business-owner panelists than in institutional-employer venues.
