• New York’s Atlantic harbor, Hudson system, Great Lakes access, and Canadian border create multiple external trade interfaces within one state.
• The Hudson-Mohawk corridor is a classic example of how topography can create durable transport corridors that shape later infrastructure investment.
• Government payroll employment should be separated analytically from government value added and from total public expenditure.
• New York City’s borough-county structure illustrates how municipal identity, county geography, and legal administration can overlap without matching common county-government models.
