How the landscape works

A water gap is a passage where a river crosses a ridge. At Delaware Water Gap, the river and surrounding wooded slopes are parts of a longer corridor. The New Jersey–Pennsylvania boundary follows political geography, while the river provides an ecological and historical connection between the two sides. A border can be a shared feature as well as a dividing line.

History

What the Paterson silk workers were protesting

Paterson became a major center of silk manufacturing, drawing workers with different languages and backgrounds into its mills. Employers sought to increase output, while workers objected to demands that could increase their workload and threaten jobs.

In 1913, more than 20,000 silk workers participated in a strike that lasted over five months. They sought changes including an eight-hour day and limits on expanded loom assignments. The strike drew national attention but ended without achieving its main demands. Paterson’s industrial history includes both the wealth created by manufacturing and workers’ efforts to control the conditions under which they produced it.

Why this mattered

Paterson’s silk workers challenged factory conditions and changes that increased the work expected of them. Their strike illustrates how industrial productivity and workers’ wellbeing can become competing priorities. A machine or new production method may increase output without improving the conditions of the people operating it.

Economy

Main activities

In 2025, professional and business services was the largest of the broad industry groups compared here by current-dollar output. Other major groups included real estate and rental and leasing, educational services, health care, and social assistance, and government and government enterprises.

Total economic output was $887.2 billion in current dollars in 2025.

Largest industry groups · 2025

  • Professional and business services: 16.2%

Production, jobs and wages answer different questions

The industry chart measures the value of production. It does not count workers. An industry with a large share of GDP need not employ the most people or pay the highest wages. Employment and wage data would be needed to answer those questions.

Read the trend, then ask what explains it

New Jersey’s population increased by about 3.0% between 2020 and 2025 in this series. That shows the size of the change. The chart alone cannot tell us how much came from births, deaths or migration.

Real GDP adjusts for changes in prices, so it helps compare production over time. Current-dollar GDP includes price changes. Neither measure tells us how income is distributed among residents.
