Consumers’ assessments on current general economic situation in Turkey compared to past 12 months, general economic situation expectation in Turkey over the next 12 months, number of people unemployed expectation over the next 12 months, buying time condition of durable goods in present period, saving time condition in present period, assessment on consumer prices change rate over the last 12 months, expectation for consumer prices change rate over the next 12 months, expectation for wages change rate over the next 12 months.

Consumer Confidence Index is calculated by the following sub- indices:
Financial situation expectation of household over the next 12 months
General economic situation expectation over the next 12 months
Number of people unemployed expectation over the next 12 months
The probability of saving over the next 12 months
The International Standard Classification of Occupations (ISCO-08) is used.
Scope of the Data
The monthly sample size of the survey is 4884 households. Person at the age of 16 and above as a representative of the household is covered. The person is selected randomly by the data entry programme.
Indices are compiled in accordance with the balance method of European Union.
The balance value is calculated for each tendency question by taking the difference between the percentages of positive and negative responses. Diffusion indices are obtained for each question by adding 100 to this balance value.
Then, the general index is calculated by taking arithmetic means of diffusion indices of the selected questions to be covered in consumer confidence index.
The index is evaluated between 0 and 200. If it is above 100, it means consumer confidence is optimistic, if it is below 100, consumer confidence is pessimistic.
Characteristics of Basic Data Sources

In 2017, four sub-indices that constitute the consumer confidence index are backcasted for the period 2004-2011, with the multivariate model-based approach.
