This statement alone goes beyond the data:
You’d have to qualify it to match the data (e.g., “over the time period in question”, “under the limitations of the data and the people included”, “some of these schools have majors such as engineering and business and some don’t”, etc.). And you don’t seem to want to do that.
And you go further, you attack others as making “excuses”, I presume, for pointing out some of these deficiencies and limitations of the data, and giving reasons for why the data is as it is.
I’m not saying this data is useless, but it needs to be put in context and interpreted.
