Online advertised vacancies fell 108,700 in August to 4,684,800, according to a survey conducted by The Conference Board, and the combined July and August losses of 262,000 bring its online help wanted data series “basically back in line with the May 2012 level,” the organization reports.

Among the top 10 occupations for labor demand, Healthcare practitioners and technical occupations experienced the only increase, +16,300, The Conference Board says.

Regarding wages of the major occupational groups advertised, based on the federal government’s average hourly wage data, the Professional occupations show average wages well above $20.00 per hour, ranging from $51 per hour for management to a low of $21 per hour for community and service occupations, The Conference Board says. The Service/Production occupations, on the other hand, average well less than $20 per hour, ranging from $21 for construction to $13 for health care support occupations. Correspondingly, many of the Professional occupations have a Bachelor’s or Associate’s degree requirement while the Services/Production Related occupations generally range from a "less than high school" to "some college" educational requirement.
