I remember this from the 80s. Resumes has marital status, hobbies, and lots of other non-essential information. I was told it was to make us look like an individual with an interesting life.
In some cultures this information is still standard on resumes. It's suprising at times to be interviewing for one of my international positions and receive resumes that state all of that and even religious affiliations.
I've just had this conversation with the Elder Chick. When I was applying for jobs, back in the Pleistocene, we were encouraged to show off soft skills, hobbies etc, and to make ourselves look 'well-rounded' and socially competent). The Chick had to explain to me in small words that my advice and experience was irrelevant to him, because he's looking for jobs in the gaming end of the computer industry which simply didn't exist when I was 20. Apparently one of the big employers explained very clearly to them in an employment seminar that the things we were encouraged to do to show team-playerness, like the Duke of Edinburgh's Award scheme, and Outward Bound courses, will actually count against
applicants in that sector now. If you've been rollerskating up Annapurna or kayaking across the Gobi Desert, even if it was to raise money for orphaned tadpoles, it means that you haven't
been devoting your time to keeping up with changes in online gaming. If you're a regular Gobi Kayaker, that's even worse because it means that you aren't just taking 6 weeks to do something you fancy doing once, you're going to be spending a lot of time on something that has no bearing whatsoever on your career. They're not saying that you should be thinking of work 24/7, but they aren't interested in somebody who'll be a 9-5 worker because he has another major interest.
