The economists found that employment polarisation in America between 1980 and 2005 was indeed most marked where jobs vulnerable to automation initially predominated.Although similar patterns of job polarisation have also been documented for Britain and other European countries, there was until recently no clear cross-country evidence about the importance of IT in explaining them.
The unemployment rate has fallen from a post-recession peak of 6.3% in June to 5.6% last month, though that is still higher than the 5.0% that many economists consider to be the "natural rate" of unemployment one that results merely from the normal or "frictional" patterns of job gains and losses at any one time.But the unemployment rate is, in fact, a poor measure of economic health.
Moreover, the lackluster pattern of job creation was consistent with the weak job growth recorded since the end of spring, when a rise in the price of gasoline put a dent in the economic expansion.
The Justice Department filed a lawsuit on Friday against John Jay College of Criminal Justice, alleging that the school engaged in a pattern of job discrimination against noncitizens who were authorized to work.

By January 2009, however, America had already been losing jobs for months; between December 2007 and June 2009, men lost about 5.4m jobs, net, and women lost 2.1m.Per the labour economists consulted by Politifact, then, the numbers show a predictable pattern of job losses during a recession.
All three indicators reveal a similar overall spatial pattern of job accessibility.
Each group contains the 20% of employment in the initial year.16 The resulting graph (Fig. 3) demonstrates an even clearer pattern of job polarisation.
The employment changes in Spain show a clear pattern of job polarisation, in which the higher and lower part of the earnings distribution increased while the middle-earnings part has shrunk.
The pattern of job growth is irregular -- the number of jobs falls during recessions and grows during recoveries -- but as of 2015, the total number of jobs is right where the long-term trend indicates that it ought to be.
