I took the newly released list of the Top 20 newspapers by circulation posted earlier to Drudge and rearranged them by percentage of gain or loss versus year ago:

20) Dallas Morning News*, -14.3%

19) Newsday, - 6.9%
18) NJ Star-Ledger, -6.1%
17) Minneapolis Star Tribune, -4.9%
16) Detroit Free Press, -4.7%
15) Los Angeles Times, -4.2%
14) Boston Globe, -3.7%
13) Washington Post, -3.4%
12) San Francisco Chronicle, -2.9%
T-10) Chicago Tribune, -2.1%
T-10) Atlanta Journal-Constitution, -2.1%
9) Houston Chronicle, -2.0%
8) New York Times, -1.9%
7) Arizona Republic, -1.1%
6) USA Today, +0.2%
5) Clevelan Plain Dealer, +0.5%
4) Wall Street Journal, +0.6%
3) Philadelphia Inquirer, +0.6%
2) New York Daily News, +1.4%
1) New York Post, +7.6%

*The Dallas Morning News is reporting for the first time since being censured in 2004 for misstating circulation figures.

Reporting Period: Six month period ending in March, 2007.

As you can see, only six out of the twenty posted positive circ numbers. It should be noted that two of those papers, USA Today and the Wall Street Journal, are the biggest papers in the country by far at 2.278 million and 2.062 million, respectively. The NY Post is also in the Top 5 in circulation, making its 7.6% increase all that more impressive in relative terms.
