# Demand Window

> Demand Window measures acceleration in job postings: not how many jobs exist, but which roles in which countries just broke out of their own pace. A free weekly chart for recruiters, HR and talent-acquisition people, and job seekers.

Score: new postings in the recent window ÷ average in the earlier window. score_norm 1.00 = same pace; 1.30 = 30% above its own pace. Fewer than 8 unique employers = "too thin", never ranked.
