As one of the leading dating sites, eHarmony thinks a lot about relationships and compatibility. The company recently released a report called "The Happiness Index: Love and Relationships in America" and eHarmony CEO Grant Langston discusses the results with Alyssa Julya Smith in Los Angeles.

Langston reveals that the study shows that 64% of Americans are "very happy" in their relationships with a partner or spouse. The results also revealed that millennials reported being the most happy, and were the most likely to value communication in their relationships.

Langston also reveals that eHarmony is responsible for 4% of American marriages, and more people are signing up for the dating service every year. He says that when people are ready to have a long and meaningful relationship, eHarmony is where they go, because of the company's focus on compatibility.
