Economics Guru is the companion data site for Alfie Meek’s Weekly Economic Update. Every chart is built directly from public data and updates itself as new numbers are released.

Using the site

Refresh schedule

The site rebuilds at about 9:00 AM and 2:00 PM Eastern every weekday, plus one run each morning, weekends included. Most federal releases come out at 8:30 AM and are on the site by the 9:00 update. Releases that come out at 10:00 AM — home sales, JOLTS, consumer confidence, the ISM surveys — appear with the 2:00 PM update. Precious-metals prices update once a day, and the Georgia county pages about once a week.

The “Latest data” tag at the top of each page shows the most recent period on it. If one source is down, the rest of the site still updates and that page keeps its last good numbers. When a release is skipped or delayed — a federal shutdown, for example — a note appears above the charts it affects.

How a chart is built

Each series is pulled from its source, stored with its full available history, and drawn without smoothing unless the chart title says otherwise (a 3-month average, for example). For CPI and PPI, year-over-year rates use the not-seasonally-adjusted indexes, the way they are reported in the press, while monthly changes use seasonally adjusted data. Anything calculated here rather than published — ratios, spreads, contributions, trailing sums — is labelled as derived in the chart’s source line. Where a chart has gray bands, they mark NBER recessions.

A few private surveys have no public data feed. For those — ISM, NFIB, the Conference Board, NAHB, the MBA, Challenger — the history is kept on file and each new month is added from the publisher’s release.
