Thanks! Do you have any good sources of salary data in mind? I think it may be interesting to collect data from Glassdoor and make similar visualization with it, but I don't know their ToC.

This dataset was created from the one collected here on HN. This was a semi-manual work, but we managed to make it somewhat uniform.

Yeah I couldn't speak to terms and conditions.

I think Indeed also collects voluntary salary data, but I don't know any other sources off the top of my head.

How do you think such visualizations are useful? Is this important for evaluation of the market when you need to recruit somebody from a concrete area?

I can't really speak to recruiting because I haven't done it (at least in tech).

It's useful for people to be able to self-assess, I think. It helps round out your assessment of a) where you are in your career, b) where you are in your field, c) question if you're satisfied.

I'm not sure it's something that should be forced on people, but it's nice to know it's there if you go looking. Once somebody's looking for answers like that, then usually there is dissatisfaction already rooted... or just plain curiosity. Nothing wrong with curiosity.

But where it's largely against the rules, or a faux pas, to discuss salaries with coworkers, it can be hard to gauge your situation if it's a concern.

Glassdoor isn't really that accurate. It doesn't reflect current market rates, it shows rates for the duration of the time the website has been around. Also, there is massive selection bias about who puts their salary up there

That's kind of interesting problem. We did thought about it, but since it's just a quick demo project, we didn't bother.

1. How to measure a credibility of data people submit?

2. How to take into account ageing of data? E.g. due to inflation.

That's a good point. I imagine in my case that could mean that my rate is even worse than it would have been during their terms. I guess it's pretty near impossible to determine an accurate measure without polling my current coworkers and bosses. haha

Best way to know current market is to ask a recruiter who will be honest with you
