* Definition of "go to college": Does this mean applying? Being accepted? Enrolling?
* Definition of "attend": Does this mean attending a single class, a single semester, or completing a full year?
* Data source: Different organizations collect data using varying methodologies, leading to different results.
* Country: College enrollment rates vary significantly across countries.
However, we can look at some relevant statistics for the United States, as it's a frequently studied country in this context:
* High school graduation rates: A significant portion of college-bound students first need to graduate high school.
* College enrollment rates: A substantial percentage of high school graduates enroll in college immediately after graduation. However, this number includes those who might only attend for a short period.
* College persistence rates: This measures the percentage of students who continue their education after their first year. This rate is often lower than initial enrollment rates.
To get a reasonable estimate, you would need to combine data on high school graduation rates, college enrollment rates, and college persistence rates. You'd then need to carefully define your criteria for "go to college" and "attend." Even then, the resulting percentage would be an approximation.
In short, there's no simple percentage answer readily available. The figure would require a detailed analysis of specific data sets and definitions.
