The number of advertised job vacancies posted online rose 52,900 in June, according to The Conference Board Help Wanted OnLine report released today. Within Washington state, the demand fell by 800 positions last month while Oregon dropped by 3,000.

The Supply/Demand rate stands at 2.4 unemployed for each vacancy. In May, there were 6.8 million more unemployed than the number of advertised vacancies, down from 11.9 million at the end of the recession in June 2009.

“Labor demand in the first half of this year has been disappointing,” said June Shelp, VP of The Conference Board. Two bright months (January and April) have been offset by declines or modest gains in the other four months of the first half of 2013.”

While labor demand is well above its pre-recession high, the strong upward trend since 2009 has stalled with 19 of the 20 largest states either flat or down in the first half of 2013. Arizona is the only large state with a positive trend.

This year, the construction trades have been relatively strong with construction up 11 percent, and maintenance and repair rising 8 percent. Online demand has been weak this year for many of the higher-wage professional occupations (healthcare professionals, architecture, business and finance, and computer workers) as well as occupations (personal care, sales, production workers, and office workers) with more modest wages.
