The Dallas Fed conducts this monthly survey of manufacturers in Texas regarding their operations in the state. Participants from across the state represent a variety of industries. In the latter half of the month, the questions for the manufacturing survey are electronically transmitted to respondents and answers are collected over a few days. About 100 manufacturers regularly participate in the Dallas Fed survey, which began collecting data in mid-2004. Participants are asked whether various indicators have increased, decreased or remained unchanged. Answers cover changes over the previous month and expectations for activity six months into the future. The breakeven point for each index is zero with positive numbers indicating growth and negative numbers reflecting decline.
