Current Revision Plan

Statistics produced byTurkStat might be subject to change in context, coverage and methodology with the purpose of adapting to the economic, social and cultural conditions of the day. These changes might result in breakings in the time dimension for some statististics and for some statistics they result in backward calculations (majorrevisions) to eliminate the breakings. In order to ensure correctin terpretation of the statistics monitored by data users, academics and policy makers; these major revisions have to be taken into account.

Within this framework a study has been conducted to retrieve information regarding the breakings caused by changes in context, coverage and methodology and major revisions in the statistics produced by TurkStat in the last 30 years. An inventory which covers all of the statistical topics currently being published has been developed as a result of this study. Information filtered from this inventory is given below.

In this context breakings in 127 statistics produced between 1989 and 2019, and major revisions implemented to eliminate these breakings have been examined by reasons and timing. In 42 out of 127 products, breakings have been experienced in various years because of reasons such as methodological change, change in base year and classification and in order to eliminate these breakings major revisions have been implemented. On the other hand in 22 out of 127 products, there have been breakings but it was not methodologically eligible to eliminate them. In 63 of 127 products, no breakings have occurred and they are comparable in time.

It is observed that breakings have occurred mostly in and after 2005. Acceleration of improvements within the scope of compliance with European Union Statistical System in 2005 and especially the coming in to effect of Statistics Law of Turkey numbered 5429 in 2005 can be seen as the main reasons for this.
