The number of jobs advertised online in the U.S. rose by 232,000 in June to approximately 4.95 million, according to a report released today by The Conference Board. June marked a strong gain after the second quarter got off to a slow start.

“Online labor demand in the first half of 2012 increased by an average of 104,000 per month, but about one-third of both the states and the 100 largest metro areas are still below their pre-recession highs for labor demand,” said June Shelp, vice president at The Conference Board.

The Conference Board’s help wanted online report collects job ad information from more than 1,000 job boards.
