To find this information, you would likely need to consult multiple sources, including:
* Massachusetts Department of Elementary and Secondary Education (DESE): They collect data on high school graduation rates and may have some information on post-secondary enrollment, though it might not be broken down precisely as you request.
* National Center for Education Statistics (NCES): This federal agency collects nationwide data on education, including college enrollment rates. You could search their database for Massachusetts-specific data, but again, the exact phrasing of your query might influence the results.
* Individual college and university enrollment data: While time-consuming, you could potentially look at the enrollment data from various colleges and universities in Massachusetts to estimate this percentage. This approach would only give a partial picture, however, as it wouldn't capture students who attend out-of-state colleges.
In short, while the exact percentage is difficult to pinpoint without extensive research across multiple data sets, you'll have the best chance of finding an approximation using the resources listed above.
