(AP) -- A survey of supply managers in a nine-state region of the Midwest and Plains is showing more signs of the coronavirus pandemic's disruptive economic impact.
A report released Monday says the Mid-American Business Conditions index sank in March to 46.7 - its lowest reading since September 2016.
The survey's confidence index plunged to a record low of 14.5.
The survey results are compiled into a collection of indexes ranging from zero to 100.
Survey organizers say any score above 50 suggests growth.
A score below that suggests decline.
The survey covers Arkansas, Iowa, Kansas, Minnesota, Missouri, Nebraska, North Dakota, Oklahoma and South Dakota.
