How many people plagiarize a year?

Estimating the exact number of people who plagiarize each year is challenging, as many instances go unreported. However, studies suggest that a significant percentage of students, particularly in higher education, admit to having plagiarized at least once, with estimates ranging from 20% to 80% depending on the institution and context. Additionally, professionals in various fields may also engage in plagiarism, though precise statistics are harder to quantify. Overall, plagiarism remains a widespread issue across educational and professional settings.
