Update: Unable to sustain last week’s rebound, the rating for “24: Live Another Day” slipped Monday.

Down 11% in the coveted adults 18-49 demographic, this week’s episode delivered a 1.6 rating. Its viewership average, however, climbed slightly to 6.3 million.

While the number did not challenge the Memorial Day mark for a new series low, Monday’s “24: Live Another Day” did endure a slight decline in the overnight metered market ratings.

Monday’s episode posted a 4.6 overnight household rating. Down 4% from last week’s 4.8, it was ahead of the 4.3 posted on Memorial Day and even with the 4.6 delivered on May 19.

Last week’s 4.8 translated into a 1.8 adults 18-49 rating with 6.2 million viewers. This week’s adults 18-49 and viewership marks will be posted later Monday afternoon.
