WqN4: Weight of the VSIC 4-digit divisions. Weight of the VSIC

4-digit divisions is the value added at current price of the
base year 2010.

- Step 4: Calculating production index of VSIC 1-digit sector

The production index at 1-digit sector of VSIC industry is the
weighted average index of the production indices of VSIC 2-digit
divisions under the VSIC 1-digit sectors.

Formula:

I 2  W qN 2
 qN
I qN 1   W qN 2

Where:
IqN1 : Production index of the VSIC 1-digit sectors.

IqN2 : Production index of the VSIC 2-digit division.

WqN2: Weight of the VSIC 2-digit divisions. Weight of the VSIC
2-digit divisions is the value added at current price of the

base year 2010.

- Step 5: Calculating production index of the whole industry

The production index of the whole industry is the weighted
average index of VSIC 1-digit sectors representing in the whole

industry.

Formula:

I 1  W qN 1
 qN
I Q 
 W qN 1

Where:
IQ: Production index of the whole industry.

IqN1: Production index of the VSIC 1-digit sectors.
