Pat Cassidy keeps WBBM on top in the mornings. No change there.
wasn't chicago's metropolitan over 9 million not too long ago. People must be leaving chicago in droves
It depends how you calculate the metro. I suspect Nielsen uses a smaller area than other statistical surveys.
From what I see, the city population has been in decline for 40 years, but the metro area has been fairly constant, up around 9 million, as you say.
The issue here is that there are two geographical areas called "MSA".
The Census and OMB define the Metropolitan Statistical Area.
Nielsen defines the Metro Survey Area.
Chicago's ratings survey metro is Cook, DuPage, Grundy, Kane, Kendall, Lake, McHenry, WIll in Illinois, Lake and Porter in Indiana, and Kenosha in WI.
2014 population was 9.391 million. 2019 was 9.523 million. There are all Nielsen metro maps at https://worldradiohistory.com/Arbitron-Market_Maps.htm
TV has Areas of Dominant Influence. A recent map: https://www.cpexecutive.com/post/morning-commute/
TV metros are based on more than station signals as they include cable coverage, too.

The Nielsen radio metro is now (2019) 9.523 million. It was 9.391 million in 2014. Nielsen has a co-owned company that takes the old American Community Survey from the Census Bureau and uses additional data to calculate annual population revisions.
Radio metros are defined by Nielsen based on the dominant origin of radio stations being listened to. The market definitions are reevaluated every year, and counties may be added or subtracted.
And Nielsen's MSA is:
Population: 7,978,400 (Black: 1,344,800) (Hispanic: 1,660,100)
Last Updated: 08-03-20 (Nielsen Subscribing Stations Only)
The city has been losing population for years, but the metro is holding and growing some.
That's the 12+ population. Nielsen does not use birth-to-death population figures.
The Spring 2020 figures are at https://worldradiohistory.com/Archive-Arbitron/Red-Blue-Books/blueSpr20.pdf The PPM data is revised during each calendar year, so you have what is called the 2021 figure.
Nielsen uses Claritas for market data; Claritas is a Nielsen owned company.

It has been over 50 years since ratings measured on a city basis. Arbitron uses counties, and full metro areas.
There are a few split counties or partial ones, but not many. Riverside and San Bernardino, CA, have pieces in several different markets. So does Fairfield County, CT.
