Even this definitive effort to define regions on the United States didn't dare to take a stand on Pittsburgh (the city is on a border). Pittsburgh is just in a category all its own!

The big story here is of an agency of dedicated statisticians and public servants working tirelessly to improve economic data in a climate of budgetary cuts to data collection. They have been very innovative in meeting that mandate. But we should also just fund our economic infrastructure.

Yes, the indices were revised. We collected additional data and improved the specification as part of the peer review process. So you should use the V2 version from now on. Thank you for asking.

One of the most surprising details in the latest CPI: an increasing share of price data was estimated, not observed.

In June, over 1/3 of #CPI imputations came from other items or locations likely due to budget cuts and staffing shortages at BLS.

We can’t fight #inflation without reliable data.

Notice of CPI collection reductions Notice of CPI collection reductions

This isn't good: "BLS is reducing sample in areas across the country. In April, BLS suspended CPI data collection entirely in Lincoln, NE, and Provo, UT. In June, BLS suspended collection entirely in Buffalo, NY." #EconSky

Economic historians take note - big methodological advances in digitizing data from old, irregularly formatted tables. But they are easy to use.
