Here, Corrections displays the recent Business Employment Dynamics data from 2010Q3 in rates. They come from administrative data. Gross job gains and gross job losses are clearly defined. Expansions and contractions give the rate of businesses that either expanded their payrolls or contracted their payrolls, in net. Openings and closings give the rate of businesses that open or closed their doors that quarter. See these six time series graphically below (click to enlarge).
