Public universities in the United States are institutions of higher education that are primarily funded by state governments. They offer a wide range of undergraduate and graduate programs and are known for their diverse student populations. These universities often provide lower tuition rates for in-state residents compared to out-of-state students, making them an accessible option for many. Many public universities are part of larger systems, such as the University of California or State University systems, which include multiple campuses. They play a crucial role in research, community service, and workforce development, contributing significantly to the local and national economy.
