Here is a link to The New York Times' piece earlier this year on the recession in golf.

Some of its highlights:

• The total number of people who play has declined or remained flat each year since 2000, dropping to about 26 million from 30 million, according to the National Golf Foundation and the Sporting Goods Manufacturers Association.

• More troubling to golf boosters, the number of people who play 25 times a year or more fell to 4.6 million in 2005 from 6.9 million in 2000, a loss of about a third.

• The industry now counts its core players as those who golf eight or more times a year. That number, too, has fallen, but more slowly: to 15 million in 2006 from 17.7 million in 2000, according to the National Golf Foundation.

• Jim Kass, the research director of the National Golf Foundation, an industry group, said the gradual but prolonged slump in golf has defied the adage, “Once a golfer, always a golfer.” About three million golfers quit playing each year, and slightly fewer than that have been picking it up. A two-year campaign by the foundation to bring new players into the game, he said, “hasn’t shown much in the way of results.”

“The man in the street will tell you that golf is booming because he sees Tiger Woods on TV,” Kass said. “But we track the reality. The reality is, while we haven’t exactly tanked, the numbers have been disappointing for some time.”

• Between 1990 and 2003, developers built more than 3,000 new golf courses in the United States, bringing the total to about 16,000. Several hundred have closed in the last few years, most of them in Arizona, Florida, Michigan and South Carolina, according to the National Golf Foundation.
