In the graphs below, the blue line is the actual index value for the month. The magenta
line is the Control Chart Change Index (CCCI) that indicates whether the change in the index value from month to month is
significant. If the line is unchanged between two or more months, there is no significant change in the rate of
growth or decline. The vertical bars labeled "P" or "T" indicate peaks (P) or troughs (T) in the economy as defined
by the National Bureau of Economic Research.

Economic Index
The Economic Index is calculated by first computing
the average of the Production, New Orders, Employment, and Supplier Deliveries Indexes for the Manufacturing and Non-manufacturing
sectors. The Economic Index is then the weighted average of the manufacturing (MEI) and non-manufacturing (NEI)
indexes using weights of 0.16 for manufacturing and 0.84 for non-manufacturing.
Economic Index
Composite Indexes
These indexes are based on the manufacturing and non-manufacturing ISM indexes. The blue line
is the composite index and the magenta line is the Control Chart Change Index.
