"The Age of MSQ Participants at Matriculation Continues to Rise. The percentage of respondents aged 23 to 25 increased to 48.7 percent in 2017 (up from 46.4 percent in 2015 and 46.9 percent in 2016), and respondents aged 20 to 22 upon matriculation dropped from 35.7 percent in 2016 to 34.5 percent in 2017. Similarly, well over half (62.6 percent) of new matriculants reported that more than a year had passed since graduating from college (up from 59.9 in 2015 and 60.6 in 2016). " -

I've spent too much time looking for applicant data (and found nothing), but this has the information regarding matriculant data.
The 2019 data isn't available yet, but I'm assuming the trend will continue to rise.
I'll keep looking for applicant data since it's fairly interesting to see, but one might have to impute/predict the numbers from applicant age (which isn't a perfect correlation with traditional/non-traditional paths due to slight differences in when people start college and how long they take to finish).
It looks like age information might be available on a per-school basis from MSAR (
You are being redirected...), but again, this isn't the same as traditional/non-traditional paths.
I think that if a program director/prehealth advisor were so inclined, it looks like AAMC might actually release this information (maybe request it under the guise of trying to encourage people at your school to consider gap years) -
Request AAMC Data
However, differential privacy is a big hot-button issue nowadays because of the US Census moving to protect their datasets, and I could see AAMC wanting to shy away from releasing too much demographic information...)
