Sites with specific demographics have become popular as a way to narrow the pool of potential matches. Successful niche sites pair people by race, sexual orientation or religion. In March 2008, the top 5 overall sites held 7% less market share than they did one year ago while the top sites from the top five major niche dating categories made considerable gains. Niche sites cater to people with special interests, such as sports fans, racing and automotive fans, medical or other professionals, people with political or religious preferences, people with medical conditions, or those living in rural farm communities.
