> For these firms, we observe 156,765,776 positions dating back to 2015 and 245,838,118 job postings since 2021, of which 198,773,384 successfully matched with their raw text description."

I'm obviously misreading this somehow. How do you have 156m positions dating back to 2015, but far more than that number in a smaller timeframe?

I think it is just poorly worded. From another point in the paper:

"Our analysis draws on a new dataset that combines LinkedIn resume and job-posting data from Revelio Labs. The dataset covers nearly 285,000 U.S. firms, more than 150 million employment spells from roughly 62 million unique workers between 2015 and 2025, and over 245 million job postings."

I guess we can read that as saying the authors identified 62 million workers who held 150 million positions over the 2015-2025 time window.

I'm still deeply skeptical about the underlying data. The 62 million represents a huge percentage of employed people in the U.S. in any of the years 2015-2025. This source shows 148 million/yr to 164 million/yr employed over that timeframe:

On the other hand, I also saw estimates saying LinkedIn has approximately 30% of the U.S. workforce with a profile on the platform. Which is wild to me.

		Ah okay, positions (actual jobs) vs job postings. Makes sense. Thanks!

You're misreading, 156m positions, and 245m job postings. A single position can have multiple job postings created for it.
