II. Process of Index Calculation
After 30 days of reference period, data is
checked by the staff working in head quarters of
TurkStat. While checking data, ratios for quantity
for production and sales, ratios for value for
production and sales and ratios for unit values
are checked. Moreover box-plot and terror
program analyses are done.

V. Index Methodology
Base year of industrial production index is
2010=100 and in every five years (ending with 0
and 5) base year is revised and after three years
this revision is done.

V. Index Methodology
While calculation of the index; mainly production
quantity of the commodities are used. However in
some commodities which have volatile unit prices
like drugs production value is used. In this case,
Producer Price Index is used as a deflator.
In addition to this in long term production sectors
like ship and train construction, hours worked is
used.

V. Index Methodology
Choosing of products and enterprises:
The products which compose 4 digit economical
activities are sorted diminishing by their
production values. The highest products and the
enterprises which produce this products are
chosen for the index till %95 of the activity is
covered.
For 2010=100 base year industrial production
index 5074 enterprises are chosen for the index.
