• Moderately concentrated

  Top three sectors employ 62% 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 (Public administration, $134,321/yr) pays 5.4× the lowest (Leisure & hospitality, $24,994/yr). Stark intra-economy class divisions on the panel; calibrate damages and lost-wages framing to that range.

• Institutional employer scale

  Average establishment employs 21 workers, typical of an institutional-employer economy where large hospitals, plants, schools, and government agencies dominate. Expect many panelists to share an employer rather than work for themselves.
