7 National Audit findings by sector
This chapter sets out the Audit's findings for each of the four infrastructure sectors, on a sector-by-sector basis.
Table 7 provides a broad overview of the capacity, utilisation and Direct Economic Contribution (DEC) for each sector and sub-sector at the national level for 2011 (the census base year used in this report).
The Audit uses the Direct Economic Contribution (DEC) methodology to quantify both the value-add attributable to infrastructure in 2011, and the projected change in overall demand for infrastructure from 2011 to 2031. Value-add reflects the cost paid for the use of infrastructure less the cost of supplying that infrastructure. DEC is reported in 2011 prices. DEC is described further in Appendix 1.
