Online job advertisements fell by 100,000 in March, resulting in a decline of over 1.1 million advertised vacancies in the past four months.

The March decline reported by the non-profit Conference Board is larger than February’s modest dip of 6,600 ads, but well below the record drops of 507,000 and 506,000 in December and January. Online job ads have declined more than 25 percent since November.

“The March numbers indicate that we are not at the bottom of the employment cycle but that the declines in labor demand may be slowing,” Gad Levanon, senior economist at The Conference Board, said this week in a news release.

The research group measures the number of new online jobs and openings re-posted from the previous month on more than 1,200 major Internet job boards and smaller Web sites that serve niche markets.
