Scope of the Data
Whole country (Turkey) is covered.

Data collection methods:
Monthly Industrial Production Survey data are provided by businesses
via Web-based data entry program .
Procedures for nonresponse:
Non-responding units are followed up on telephone or by interviewers. When a unit refuses to respond, the unit is reminded of its legal obligation to respond and legal procedure begins.
Information form on revision will be carried out in 2016 for the statistics produced in this scope of this press release can be accessed from the link below.
Treatment of missing data:
In non response situation, change ratios over to the previous month or year are used for imputation.
Verification of processing:
Staff regularly reviews the compilation process comparing the preceding figures.
Seasonal and calendar related effects prevent observing the general tendency of data because of their temporary characteristics. Therefore, identification of seasonal patterns of short term indicators plays crucial role in order to make reliable comparisons between consecutive periods.
Currently, Turkstat carries out the seasonal adjustment of industrial production indexes, using TRAMO-SEATS methodology based on ARIMA (Autoregressive Integrated Moving Average) model estimation developed by the Banco de Espana and also suggested by Eurostat. The software that is used for the application of this method is TRAMO-SEATS for Windows (TSW).
Seasonal Adjustment Process
The process of seasonal and calendar adjustment of Industrial Production Indexes begins at the end of each year with determination of the specification of models of the next year. This specified model structure is kept fixed throughout the year to adjust seasonally and/or calendar effects. At the end of the year, just like the previous year, specification of econometric estimation models for the following year is determined. The identified process repeats itself in a cyclical manner each year.
Total Industrial Production Index, 5 subgroups according to Main Industrial Groupings classification, 3 sections and 29 subdivisions according to NACE Rev.2 classification have been seasonally and calendar adjusted. While 33 subseries of Industrial Production Index contain both seasonal and calendar effects, 1 subseries contain only seasonality.
Direct or Indirect Approach
Seasonally and calendar adjusted figures of total Industrial Production Index, Mining and Quarrying Sector (B), Manufacturing industry (C) and Electricity, Gas, Steam and Air Conditioning Supply (D) sections have been produced by indirect approach. The individual subseries of Industrial Production Index by MIGs and NACE Rev.2 classification are firstly seasonally adjusted and then aggregated to derive seasonally and calendar adjusted totals. The advantages of indirect approach are calculation of contributions to growth from components of main aggregates and retaining additivity.
Seasonal adjustment procedure is subject to revisions over time because of the re-estimation of seasonal component as new observations are added. These revisions are implemented on the data of the last three years excluding the current year.
Adjusted data has been published in 3 different ways.
” data is derived from unadjusted data by removing calendar and holiday originated effects. Calendar adjusted data should be used in comparisons regarding the same month/period of the previous year.
” data is derived from unadjusted data by removing effects originating from seasonal effects. Seasonally adjusted data should be used in comparisons regarding the previous month/period.
- If unadjusted data contains both calendar and holiday, and seasonal effects, “
seasonally and calendar adjusted
” data is derived by removing these effects. Seasonally and calendar adjusted data should be used in comparisons regarding the previous month/period.
The details of data which are disseminated in press release are given below:
1- Monthly Industrial Production Index (2010=100),
2- Calendar adjusted Monthly Industrial Production Index (2010=100),
3- Seasonally and calendar adjusted Monthly Industrial Production Index (2010=100),
4- Calendar Adjusted Percentage Change over the Same Month of the Previous Year,
5- Seasonal and Calendar Adjusted Percentage Change over the Previous Month.
• Consistency with other indicators:
As a part of the review process, the index is compared with industrial turnover index and the data from other organizations.
QUARTERLY INDEX and RATE of CHANGES
Change rates compared with the same quarter of previous year (Annual comparison):
Percentage change of the average of monthly indices which are calculated in current quarter with the average of monthly indices which are calculated in the same quarter of previous year.
Months: April, May, June
Annual change of quarter= (Q2_2013/ Q2_2012)*100-100
Change rates compared with the previous quarter (Quarterly comparison):
Percentage change of the average of monthly indices which are calculated in current quarter with the average of monthly indices which are calculated in previous quarter.
First Quarter Months: January, February, March
Second Quarter Months: April, May, June
Change rates compared with previous quarter= (Q2_2013/Q1_2013)*100-100
Annual Average Change:
Percentage of change of average of monthly indices which are calculated in current year compared with average of monthly indices of previous year.
Months: January, February, March, April, May, June, July, August, September, October, November, December
Annual Average Change=(Y1_2013/Y1_2012)*100-100
