(CNSNews.com) - President Barack Obama averaged a 49.1 percent job approval during his first term in office, among the lowest for post-World War II presidents, according to a new Gallup poll.

Only Jimmy Carter and Gerald Ford had lower job approval averages in their first terms, Gallup reported.

Here's how the Post-WWII presidents stack up:

First-Term Average Approval Ratings:

Johnson - 74.2%
Kennedy - 70.1%
Eisenhower 69.6%
G.W. Bush - 62.2%
G.H.W. Bush - 60.9%
Nixon - 55.8%
Truman - 55.6%
Reagan - 50.3%
Clinton - 49.6%
Obama - 49.1%
Ford - 47.2%
Carter - 45.5%

According to Gallup, Obama's first-term approval average, like those of most presidents with lower first-term averages, "was likely dragged down by a sluggish economy."

Approval ratings for both Clinton and Reagan climbed in their second terms as the economy improved. The same thing happened to Obama: His approval rating increased from a dismal 44.4 percent average in his third year, to a 48.1 percent average in his fourth year in office.

The results are based on aggregated data from Gallup Daily tracking throughout Obama's first term in office.
