How many people climbed the Appalachian mountains?

The Appalachian Mountains are a vast range extending over 2,000 miles, and while millions of people hike and explore various trails within the region annually, there isn't a specific count of how many have "climbed" the entire range. The Appalachian Trail, which runs about 2,190 miles from Georgia to Maine, has seen over 15,000 hikers complete the entire trail since its completion in the 1930s. Each year, thousands attempt to hike sections or complete the entire trail.
