January 6, 2011 – Online advertised vacancies were basically unchanged as they dipped 9,400 in December to 4,447,800, according to The Conference Board’s Help Wanted OnLine Data Series. The nation's supply/demand rate stood at 3.39 unemployed for every advertised vacancy in November (the last available unemployment data) a figure that is down from a peak of 4.73 in October 2009. Nationally, there are 10.7 million more unemployed than advertised vacancies. “The year 2010 ended with a continuation of the lackluster labor demand we have seen throughout the last half of this year,” said June Shelp, vice president at The Conference Board. “In the last half of 2010, advertised vacancies for workers in production, transportation, and construction and maintenance occupations increased, but demand for sales staff and workers in food preparation and serving, which rose in early 2010, moderated.” Among the top 10 occupation groups with the largest numbers of online advertised vacancies, sales and related occupations posted the largest December increase in the number of advertised vacancies, up 10,300 to 459,800 after three months of losses. Computer and mathematical science occupations posted a December decrease of 8,500 to 596,400 following gains throughout the fall.
