Quarterly data, not seasonally adjusted
The National Highway Construction Cost Index (NHCCI) is a price index that tracks price changes associated with highway construction costs.
|National Highway Construction Cost Index||2012 Quarter 1||2013 Quarter 1|
|National Highway Construction Cost Index (Index: Q1 2003 = 1.00)||1.11||1.10|
|Percent change from same quarter previous year||+ 5.9%||- 1.3%|
NOTES: The current value is compared to the value from the same period in the previous year to account for seasonality.
The NHCCI is updated quarterly and has a base period of the First Quarter of 2003. The data series began with 45 states in 2003 and currently includes 48 states; Alaska and Hawaii are excluded due to unique cost issues.
The NHCCI does not have the exact same coverage as the C30 (Value of Construction Put in Place) dataset from the Census Bureau. The C30 data only covers the value of new construction, and the NHCCI tracks materials and services purchased by states.
