Column chart
Unemployment rate by CPS rotation group, first vs eighth interview
A column chart of rotation group bias in the US Current Population Survey: the unemployment rate reported by households in their first interview against those in their eighth, in the same months, for 1976 to 1980, 2009 to 2013 and the first half of 2014. The gap grew from 0.5 to 1.4 points, which makes it one of the clearest published examples of panel conditioning. Research teams can use it to explain why repeat participants need a fresh-cohort control.
