TV Nation: 112.8 million strong

There are 1.3% more of us in TV Nation than last season, per Nielsen Media Research. Nielsen estimatesOldtvset1  that there’ll be 112.8 million TV households in the U.S. by January 2008, a healthy spike from last season’s 111.4 million TV-friendly households. The total number of viewers aged 2 and up is estimated at 286 million, a 1% gain from last season. Much to advertisers’ chagrin, baby boomers in the 55-69 are the fastest-growing demo group, up 3.8% to 32.8 million. The largest demo group overall remains the coveted adults 18-49 skew, projected to grow 0.3% to 131 million strong. The persons 12-34 demo is flat year-to-year at 28.4 million, while the teen contingent (12-17s) is the only demo projected to decline — 0.4% — to 24.7 million by the start of the new year.

On the market-by-market growth front, Dallas-Ft. Worth has knocked San Francisco out as the nation’s fifth-largest TV market, with Frisco dropping to No. 6. Atlanta and Washington, D.C. have also flopped spots, with Atlanta now ranking No. 8 and D.C. dropping to No. 9. (The rest of the top 10 remains the same). Indianapolis has been edged out of the top 25 by Charlotte, N.C.
