Idaho, located in the northwestern United States, is divided into 44 counties and includes over 200 incorporated cities, with Boise serving as both the state capital and largest city. Other significant cities include Meridian, Nampa, Idaho Falls, and Pocatello. Idaho has a population of approximately 1.9 million people, making it the 38th most populous state in the U.S. Idaho covers an expansive area of about 83,570 square miles, ranking it as the 14th largest state by land area. The state’s landscape is known for its mountainous terrain, vast wilderness, and significant agricultural areas, particularly in the Snake River Plain. Idaho’s major airports include Boise Airport (BOI), which is the largest and busiest, providing both domestic and limited international flights. Other important regional airports include Idaho Falls Regional Airport (IDA) and Spokane International Airport (GEG), located nearby in Washington, serving northern Idaho. The state is home to several higher education institutions, including Boise State University, the University of Idaho in Moscow, and Idaho State University in Pocatello. These universities play a critical role in education and research, particularly in areas such as engineering, agriculture, and health sciences. The healthcare system in Idaho is anchored by major hospitals such as St. Luke’s Health System, the largest in the state, with its main facility in Boise, and St. Alphonsus Regional Medical Center, also in Boise, known for its trauma and cardiac care. Other notable hospitals include Eastern Idaho Regional Medical Center in Idaho Falls and Portneuf Medical Center in Pocatello. Idaho’s healthcare infrastructure is designed to meet the needs of both its urban and rural populations, with facilities spread across the state providing a wide range of services. As the population continues to grow, particularly in the Boise metropolitan area, the demand for healthcare and education has increased, prompting expansions in both sectors to accommodate the needs of Idaho’s residents.
