A great diversity of online dating services currently exists.
Some have a broad membership base of diverse users looking for many different types of relationships.
Such companies offer a wide variety of unmoderated matchmaking services, most of which are profile-based.
Online dating services allow users to become "members" by creating a profile and uploading personal information including (but not limited to) age, gender, sexual orientation, location, and appearance.
Online dating is also relatively popular among the college-educated, as well as among urban and suburban residents.
And 38% of Americans who are single and actively looking for a partner have used online dating at one point or another.
