* Statistically different from zero at the 90-percent confidence level.

^{1} The 2-year-average median is the sum of two inflation-adjusted single-year medians divided by 2.

^{2} The 2004 data have been revised to reflect a correction to the weights in the 2005 ASEC.

^{3} A 90-percent confidence interval is a measure of an estimate's variability. The larger the confidence interval in relation to the size of the estimate, the less reliable the estimate. For more information see Standard Errors and their Use.

* Statistically different from zero at the 90-percent confidence level.

^{1} The 2004 and 2005 data have been revised since originally published.

^{2} The data in this column are derived from estimates that include 2005 twice--the first in the 2004-2005 average and the second in the 2005-2006 average. Therefore, estimates in this column are equivalent to measuring half of the percentage-point difference between 2004 and 2006.

^{3} A 90-percent confidence interval is a measure of an estimate's variability. The larger the confidence interval in relation to the size of the estimate, the less reliable the estimate. For more information see Standard Errors and their Use.
