(CNSNews.com) - President Barack Obama’s job approval among young people between the ages of 18 and 29 hit an all-time low in the Gallup poll last week, according to survey data released today.

In the seven-day period that ended on Sept. 25, only 45 percent of Americans in that age group said they approved of the way Obama was handling his job as president. That was down from 47 percent the previous week.

The president’s job approval among the 18-to-29 age group had dropped as low as 46 percent on three previous occasions—the weeks ending Aug. 28, 2011, May 1, 2011, and Aug. 15, 2010—but it had never dropped below that threshold.

Each week, Gallup publishes the president’s job approval among various demographic groups, including four age brackets: 18 to 29, 30 to 49, 50 to 64, and 65 and above.

Among these age brackets, Obama’s approval is currently lowest among those 65 and older. Last week, only 35 percent in this group said they approved of the way Obama was handling his job as president. (Obama’s approval hit an all-time low of 32 percent among those 65 and older back in the first week of August.)

In both of the middle age groups—30 to 49 and 50 to 64—42 percent said they approved of the job Obama was doing.

So far during his presidency, Obama’s approval among Americans in the 18-to-29 age group has peaked at 75 percent, a level it hit in the week he was inaugurated and two other weeks in the first half of 2009. It has now dropped 30 points from that peak.
