I missed my edit window, but here's the absolute plot: https://www.dropbox.com/s/8uhphbrpgygcpgy/majors.png?dl=0

Contrary to the worry that not enough people are majoring in CS, what this shows is that CS is growing out of the relatively small math/physics group and into the larger mass appeal groups.

And maybe what this shows best of all is that Biomed is through the roof.

On the whole, CS has grown slightly more than 3x since 1980 and biomed has grown slightly less than 3x since 1980, but those are the top two sciences.

EDIT:

If I divide 2014 numbers by 1970 numbers, here's the "overall" growth chart for all majors in the data that Dan Wang linked to. Sliced this way, CS is the fastest growing major in the sciences by a long, long way. That is somewhat unfair since CS is the newest, the number is big because the field was tiny in 1970. But, this is a more fair a way to look at this than the article, IMO.

The total number of majors grew by 2.26x between 1970 and 2014, so majors over that are actually growing, and under that are shrinking relative to other majors. Everything above Theology is improving, everything in Family and consumer sciences is shrinking.

Oh, wait, this is actually the biggest revelation to me so far: Engineering has actually shrunk a little, and Math & Physics have shrunk a lot. CS is growing, not shrinking.

Here's a plot of the sciences as a percentage of total majors, this is more indicative of the growth of each field relative to other fields than either the absolute numbers or the delta plots in the article: https://www.dropbox.com/s/xuxithrti6nyljm/majorsSciencesPerc...
