Hey -- we're not doing our usual light-hearted romp through the Swells society column this weekend, because we've got sad news. The doyenne of Swells, Catherine Bigelow, announced in this week's column that she's been asked to take the Chron's "voluntary buyout package," so this is it for your mathematically-inclined socialite review.

Best of luck to you, C.Big, and we know you'll end up on your feet, tripping the light fantastic, and we hope you'll tell us all about it when you get there! We'll miss you very much.

So here's your melancholy last Swells By The Numbers. We've had fun compiling these too.

Number of people pictured in today's Swells by the Numbers: 99.

Number of people pictured whom we recognize: 4 (A friend of ours won an award for her work againsty domestic violence! Also, Kamala Harris, and our very last Dede Wilsey. Regretful sigh.)

Minority count: 11 (11.1%).

Getty v. Traina: 0-1.

Number of years C.Big was with the Chron: 12.

Your numbers for Swells by the Numbers's entire run, after the jump.

Our last picture of Dede Wilsey ever, by Thomas J. Gibbons for the Chron.
