Wide wage spread

Highest-paid sector (Manufacturing, $148,859/yr) pays 6.7× the lowest (Leisure & hospitality, $22,237/yr). Stark intra-economy class divisions on the panel; calibrate damages and lost-wages framing to that range.
Mixed business scale

Average establishment employs 13 workers, a mix of institutional employers and small businesses. Both employed-by-large-institution and small-business-owner perspectives are likely on the panel.

Largest employers

Principal employers by headcount

So trade, transportation & utilities is the largest sector by employment here, but most of the parish's five biggest named employers sit outside it. A panelist who works somewhere you recognize is probably not working where most of this parish works; ask where they work before assuming either pattern fits them.
