Unfiltered Data

Two views of every series, side by side. The gap is the filter. We publish the raw column and the filtered column for the same observation, on the same date, so the cost of the transformation is visible — not described.

Series

CPI

Raw (NSA) vs. seasonally adjusted. The gap is what BLS's seasonal filter takes out.
M2 Money Supply

Raw (NSA) vs. seasonally adjusted. The gap is the seasonal swing in money demand.
Unemployment

Raw (NSA) vs. seasonally adjusted. The gap is the labor cycle the filter erases.
Bitcoin

Coinbase vs. Kraken daily close. The gap is the venue itself acting as a filter.

What "unfiltered" means here

Every number you read in a chart or a headline has been transformed somewhere upstream. Seasonal adjustment, base-year indexing, exchange-specific clearing — none of that is part of the underlying reality, and yet it is what gets quoted.

This site does one thing: for each series we publish, we put two views next to each other. One is the least-transformed version available; the other is the version most commonly cited. The Δ column is what filtering does. There is no commentary on top.

Updates

Series refresh nightly from primary sources. Each series page shows the timestamp of the last successful fetch and the number of rows after the date join.
