U.S. online job ads rose by 164,600 in August to a total of about 5.2 million, according to The Conference Board’s report on online jobs ads released today. The increase follows a loss of 15,500 job ads in July.

“Labor demand has shown some renewed strength over the past three months with an average increase of 102,000 per month,” said Gad Levanon, director of macroeconomics and labor markets at The Conference Board. “The 2014 gains through August are an improvement over the slower-paced gains of 2013 for the same time period.”

Professional occupations — business and finance, computer and math, and healthcare — continued to gain job ads in August after earlier 2014 losses. The services/production occupations also showed gains in office and administration, sales, and food preparation.
