These salaries definitely have reporting bias, and the top paying companies are definitely outliers by definition. But one important point with regards to BLS data is that they don't account for total compensation, which is a large part of compensation especially in tech, sometimes greater than 50% of one's total package.
Yeah these are based on numbers from Levels, which is known to report salaries from top tech companies. I'm sure numbers from BLS or even something like Glassdoor are far more accurate when thinking about the industry as a whole.
fascinating that the divergence between the highest paying companies and the median still grows even in a down marker. highest paying companies still increasing comp despite the median decreasing over the same year period
These are aggregate metrics. As such, individuals may have seen their salaries stay the same or even go up, but if the employees at the top of the pay scale are removed (layed off, or even a simple selection bias in the dataset), the median will still drop.
Also wouldn't the dataset being from different number of people affect this? During 2021 probably much more people with higher pay self reported their pay on the website and 2022 just didn't see that much contribution?
