Conjunctural index of construction in the Basque Country by quarter. Corrected data.

The Conjunctural Construction Index (CCI) is an indicator of a cyclical nature that estimates the evolution of production and employment in the construction sector of the Basque Country. Information units are the companies that carry out construction work. The Corrected Construction Conjuncture Index of calendar effects (number of working days and holidays) offers comparable values year-on-year, while quarter-on-quarter comparisons use the seasonally adjusted construction conjuncture index (corrected the effect of periodic fluctuations of less than one year).
