"Our Texas Index eased again in August, giving back its July increase. Volatility in residential building permits has been a big factor this year in keeping our Texas Index flat. Permits eased significantly in August, countering the gains seen in most other components of the index," said Robert Dye, Chief Economist at Comerica Bank. "Also, recent job growth has been uneven. Low natural gas prices have been a dampening force on some parts of the energy sector. Fortunately, oil prices have remained firm, providing plenty of incentive for drilling activity. I expect the Texas economy to continue to grow through the end of this year."

*State level exports data have not been reported for August due to the federal government shut-down. We estimated an August export number in order to calculate the total index.

The Texas Economic Activity Index consists of seven variables, as follows: nonfarm payrolls, exports, sales tax revenues, hotel occupancy rates, continuing claims for unemployment insurance, building permits and Baker Hughes rotary rig count. All data are seasonally adjusted, as necessary, and indexed to a base year of 2008. Nominal values have been converted to constant dollar values. Index levels are expressed in terms of three-month moving averages.
