>software engineering had a historically larger amount of women which faced a decline post-80s. How much resemblance does software engineering pre-80's and post-80's have with each other? Furthermore, how much generalizations can one make when the sample size is small? Presumably when computer programming first became a distinct activity, the pool of players were significantly smaller than it currently is.
