Methodology
Every page on HiringTrends shows derived numbers — percentiles, demand share, posting counts. Here’s how each of them is computed.

How we compute salary percentiles
Definition of p25/p50/p75/p90, the sample window we use, and how we handle ranged or missing values.
Demand share — definition and formula
How we measure the share of tech postings mentioning each stack, and what a healthy WoW delta looks like.
Posting counts — what counts, what doesn’t
Which job rows we include in counts, how we handle reposts, and the 26-week rolling window.
Freshness and the daily crawl
Our daily-crawl cadence, the rollup refresh schedule, and how we surface the as-of date on every page.
