Seasonally adjusted
Seasonally adjusted data has been statistically corrected to remove predictable within-year patterns — holiday retail spikes, winter construction slowdowns, summer tourism swings — so that month-to-month comparisons reflect real underlying change rather than the calendar. Unemployment claims always rise every December; the seasonally adjusted figure strips that out to show the genuine trend.
Why it matters
Most monthly series here are shown seasonally adjusted so a reader isn't misled by predictable calendar noise.
