IPEDS is typically a year or two old. Usually better to use the most recent common data set.
Section C1 has the freshman class admissions data. For Vassar class of 2023, 870/2887 men were accepted (30.1%) acceptance rate, 1257/6074 women were accepted (20.7%).
@Diaz42 , you seem to be quite concerned about excessive partying. In general, the more Greek presence at a school, the more hard partying there is. There also tends to be more partying at more rural schools. Having said all that, there is partying at Williams and every one of the schools mentioned so far. And there are different kinds of partying. Some partying is going to be keggers, some of it’s going to be hard liquor, some of it’s going to be wacky tabacky. No doubt it can be all of those things.
I would say that of the schools mentioned, a list might be loosely ordered in terms of most partying to least as below.
This is based mostly based on what I’ve gleaned over the years and I am sure that I am going to be robustly refuted ?. (Yes, there is probably marginal difference between most of these.)
The list seems reasonable to me. Somewhat surprised that Davidson is tied at #2.
For comparison, below you will find Princeton Review’s survey-based rankings pertaining to high alcohol consumption:
Lots of Hard Liquor
Lots of Beer
Syracuse, Wake Forest & Tulane made both lists.
As did Delaware, Union, Colgate, & West Virginia.
@Lindagaf’s list looks reasonable to me - I’m not surprised at Presbyterian founded Davidson’s tie at #2 at all. Some of the biggest tipplers I know are mainline Christians. 
And, not to guild the lily, as it were, I would add that Wesleyan, despite its reputation for weed, has a residential system that leans heavily on university-furnished houses with kitchens, especially junior and senior year. I think as a result, there is a fairly serious “foodie” culture that competes with the other consumable cultures on campus.
As stated, geosciences include geology and oceanography (as well as other fields such as meteorology); mineralogy, in my opinion, would be more accurately described as a foundational element of geology rather than as a parallel field; geoscience and earth science translate to equivalent terms.
“How does Williams help student on the engineering track?”
We’ve discussed this in some other threads on engineering and LACs, and Williams doesn’t have engineering but it’s really strong in your other majors, so they could prepare you for engineering. Vassar is a good suggestion for a slightly less selective college, I grew up a few minutes from Vassar and have been at Williams, and the two campuses are pretty different.
