Where you find affluence, infidelity tends to follow

After 10 years establishing itself as the infidelity destination on the Internet, AshleyMadison.com has finally built enough of a membership — a whopping 210,000 members in the Philadelphia region alone — that it has now begun identifying the neighborhoods most likely to cheat.

And like many other urban areas across the United States, some of Philadelphia’s most affluent neighborhoods and areas have the highest percent of AshleyMadison members. The top of the list: the Main Line.

Generally thought of as home to the region’s most bucolic streets and most successful residents, almost 3 percent of all adults on the Main Line have a profile on AshleyMadison, the company told Metro yesterday.

“Just like in other cities, there is a correlation between affairs and affluence,” website founder Noel Biderman said in an interview, noting that many affluent neighborhoods have women who work, raising the percent of female members. “Those people (with wealth) not only usually are type A people and born to take risks, but they’re also in environments that remove them from the families for business. And they have many temptations thrown at them.”

After the Main Line, the Philadelphia region’s list includes: Old City, Huntington Valley, Fox Chase, Chestnut Hill/Germantown, Washington Square West, Fairmount, Northern Liberties, Manayunk and Center City.

Since 2002, the website has grown to nearly 15 million members worldwide.

He said working women continue to push the female membership higher. “The female ratio has been the faster growing of the two [sexes].”

Website for old men and women

Two of the most intriguing — head-scratching? — findings when delving into the demographics of AshleyMadison members are the growing number of young women and the huge discrepancy between male and female senior citizens.

The site, which touts itself as “the world’s fastest growing paying social network” and claims 14.8 million followers, says it has 20,000 male members over 70 years old. Yet not a single member is a woman over 70.

At the same time, the male-to-female ratio for members under 30 has now reached one-to-one, Biderman said.
