New Jersey continues to stand out as one of the most affluent, educated, and highly developed states in the United States. With a median household income of $99,781 in 2023—the second-highest nationwide—nearly 10% of households in the state are millionaires, the highest proportion in the country. The state’s public school system consistently ranks among the best in the nation, supporting a highly educated population.

Diversity is a hallmark of New Jersey, with a quarter of residents being foreign-born, second only to California. In 2025, the state was recognized for having the healthiest population overall, reflecting strong healthcare access, wellness initiatives, and community engagement. High scores on both the American Human Development Index and the standard Human Development Index underscore New Jersey’s quality of life. However, these advantages come with high living costs, making it one of the most expensive states for residents.

New Jersey also faces environmental challenges. Research from the U.S. National Oceanic and Atmospheric Administration highlights that the state has been the fastest-warming in the U.S. over the past century, a trend largely linked to rising temperatures in the North Atlantic Ocean. This climate shift has implications for public health, infrastructure, and long-term planning as New Jersey balances growth, prosperity, and sustainability.
