However, a commonly cited statistic is that around 35-40% of Americans aged 25-29 have a bachelor's degree or higher. This isn't the percentage of *all* students who *start* college, but rather the percentage of the population within that age range who have achieved that level of education. The actual percentage of students who *begin* college and ultimately earn a bachelor's degree is lower. Many students drop out, change paths, or take longer than four years to complete their degrees.
