The Federal Reserve Bank of Dallas will no longer publish the Texas Industrial Production Index (TIPI), a monthly indicator of the Texas manufacturing industry.

TIPI, a measure of output in the state’s manufacturing, mining and utilities sectors, had been a regional counterpart to the national industrial production and capacity utilization index compiled by the Federal Reserve’s Board of Governors. However, over the years, changes in reporting and deregulation of the Texas electricity market resulted in the discontinuation of some of the data series used in TIPI calculations, making it a less reliable indicator of manufacturing activity.

The Dallas Fed will continue to track regional manufacturing activity through the Texas Manufacturing Outlook Survey (TMOS), which it has published since 2005. TMOS, which is available about three weeks earlier than other important manufacturing indicators, is a monthly survey based on manufacturers’ responses to questions about their Texas operations. The production index in the TMOS is a good measure of Texas manufacturing activity.
