Notes:

1. Consumer confidence index data series range from 0-200, 100 was critical point threshold, above 100 was full of confidence, below 100 was lack of confidence.

2. The data before November of 2009 were used in 1996 = 100 as the standardized treatment (June 1996: consumer expectation index was 115.2, consumer satisfaction index was 118.9, consumer confidence index was 116.7).

3. Historical data conversion: consumer confidence index before November 2009 (referred to as Bi), a new series of consumer confidence index (referred to as Ai) = series of consumer confidence index in June 1996*Bi/00; for example, A1 (new consumer expectations index in November 2009) = 115.2 (consumer expectations index in June 1996) * 89.4 (B1, old consumer expectations index value)/100=103.
