Yes, I think this visualization would be FAR more helpful if the weighted lines were adjusted by the relative population in each group. Or at the very least make each group a different sized bubble so you aren't surprised when so many lines seem to keep going back to it.

All the cute nurses I've met are married. They seem to get married at a young age (20-23).

> I say this as a person who met a woman who said she basically doesn't date anyone who has anything less than a Master's degree.

At first, I thought that is petty. However, such bluntness is helpful to you; you get to very quickly (i.e. never date) select against a potentially improper partner. Supposing you have a Bachelor's, would you want to date a woman who only dated men with a Bachelor's degree or higher?

My first guess is that she is avoiding sub-Master's degreed men as a means to avoid boring, wealthy, and/or immature men. My second guess is that she might be trying to use a simple criterion to select among a relatively high volume of date offers.

Teaching as a career gets a lot of flak for being underpaid, but in many cases it's actually paid pretty well on top of having solid retirement benefits, an incredible schedule, and a lot of stability. The pay, if it's low, is also not as much of an issue if the other partner makes a large amount of money, as is often the case right now for software developers. It can be an incredibly family friendly career.

My SO is going into teaching, at least temporarily for a few years, in a medium-COL city. She'll be making $55k-$65k in base salary, depending on if she teaches 10 months or 12 months out of the year, plus full retirement benefits, and they also provided her with enough scholarships just for taking the job that she has no college debt at all. Meanwhile I know engineering graduates (not necessarily software) who started in roughly the same range, with considerable debt, not as much stability, no retirement beyond a 401(k) with a pitiful match, and just a week or two off per year.

Teachers have very, very predictable schedules compared to practically everyone else. They're part of a reliable industry. They have a very clear career progression ahead of them. They have holidays, maternity leave, etc. It's very conducive to marriage and raising kids.

There are two things to consider from that.

1: people who want a stable married-with-kids life are likely to also want a stable, predictable career

2: People who happen to be in a stable, predictable career find it easier to say yes to marriage and kids

I think it's a familiarity bias with the occupation. More women have business degrees than nursing or education [1], but it may not seem so since business degree holders are more dispersed among types of businesses. The link seems to indicate that software developers are just as likely to marry accountants or nurses as teachers.
