Main Industries: Manufacturing, particularly the aviation industry, declined while retail and service employment boomed. A dramatic increase in office construction with some buildings exceeding over 1,000,000 square feet, changed the Nassau horizon and established it as a major place of white collar employment.

Education: Nassau County is home to numerous colleges and universities, including Adelphi University, Molloy College, New York Institute of Technology, SUNY Old Westbury, Nassau Community College, Hofstra University, C. W. Post Campus of Long Island University, United States Merchant Marine Academy and Webb Institute.

Land: Nassau County has two nationally protected areas of Oyster Bay National Wildlife Refuge and Sagamore Hill National Historic Site.
