Unlike most other NBC TV shows that aired last season, the viewership ratings for Chicago Fire were actually up year to year. Could they continue to rise or, will they fall? Could this series be in danger of being cancelled or is it sure to be renewed for a sixth season? Stay tuned.

Chicago Fire follows the lives and work of the firefighters, Rescue Squad, and paramedics of Chicago Firehouse 51. No occupation is more stressful or dangerous, yet so rewarding and exhilarating. These courageous men and women forge headfirst into danger when everyone else is running the other way. The TV show’s cast includes Jesse Spencer, Taylor Kinney, Monica Raymund, Eamonn Walker, David Eigenberg, Joe Minso, Yuri Sardarov, Christian Stolte, Kara Killmer, and Steven R. McQueen.

The ratings are typically the best indication of a show’s likelihood of staying on the air. The higher the ratings (particularly the 18-49 demo), the better the chances for survival. This chart will be updated as new ratings data becomes available — usually the next day, around 11:30am EST/8:30am PST. Refresh to see the latest.

For comparisons: The fourth season of Chicago Fire  averaged a 1.75 rating in the 18-49 demographic with 8.01 million viewers (live + same day ratings).

Note: These are the Live + Same Day Ratings which include “live” viewing plus delayed DVR viewing, up until 3am local time that same night. Ratings marked with an “*” are the fast affiliate ratings and will be updated with the Live+SD numbers when they are made available. Typically, networks get paid for C+3 ratings which includes DVR viewing within three days of the original airing when commercials are watched. Those numbers are rarely released to the press.
