The Federal Reserve Bank of Kansas City Survey of Manufacturers provides information on current manufacturing activity in the Tenth District (Colorado, Kansas, Nebraska, Oklahoma, Wyoming, northern New Mexico, and western Missouri). The monthly survey consists of approximately 150 manufacturing plants across the district of which about 110 respond. Survey results reveal changes in several indicators of manufacturing activity including production, shipments, new orders, and employment along with changes in prices of raw materials and finished products. The diffusion index is calculated as the difference between the percentage of total reporting increases and the percentage reporting decreases.
