That's actually included in the document! I know it's really long. It's on page 32. I decided to add up all of the masters/doctorate information for both male and female to find this ratio. I still don't know the percentage of which gender applies for higher education, but it looks like out of 14,710 people in either a master's or doctorate program for SLP, speech and hearing, and audiology males make up 7%.
This data is a lot more recent. It observed the school years 2012-2013. The data research covers beyond just gender, but according to the information provided by the schools males seem to make up close to 6% of the undergraduate students and also make up 4.75% of master's students.

This was shown on the second to last bullet on page 15 and the chart on page 29. It doesn't take into account how many males applied compared to women , but I thought that this at least showed the stats are similar between undergrad and grad students for SLP.
If you're applying to graduate school at all you are automatically considered an independent. This is the case for everyone. Also fill out your fasfa as soon as you're able to for the next school year.
