The 2017-18 Climate Center: League Averages


The Climate Center helps you keep up with some of this site's bigger-picture numbers on a week-to-week basis. Though most of the A18-49+ posts aren't updated until the summer, this can keep you posted on how things are developing while the season is ongoing.

The League Averages post covers the numbers that really make A18-49+ go: the 'league average,' which is an average of all ratings for original non-sports series on the big four networks during the traditional 35- or 36-week regular season. No sports, no reruns, no specials, no movies, no sustaining programming included!

These numbers are up to date through Wednesday, May 23.

The two numbers actually used to calculate A18-49+ (and projected A18-49+) are:
LeAv - Adults 18-49 league average for the full 2017-18 season to date.
ProjLA - Projection of the end-of-season 18-49 league average, derived by applying the current year-to-year trend (y2y) to last season's final average.

*- New this year: in weeks one and two, the projection is a blend of the pre-season projection and the projection that results from the current year-to-year trend. Starting in week three, it will use only the current year-to-year trend.

*² - Beginning in week 14, the year-to-year comparisons are no longer through the same number of weeks completed, but through the same number of weeks till the end of the season. So numbers through 14 weeks of 2017-18 are compared with 15 weeks of 2016-17, since both are 21 weeks from the end of the season.

Also included in the table:
LAwk - The 18-49 league average within each week individually
OrigHrs - The number of original hours that went into this week's league average.
LYHrs - The number of original hours that went into the average from the same week last year.
