Final answer:
An unmarried person is commonly referred to as a bachelor. Being unmarried does not necessarily mean being single or without a partner, as individuals can choose to cohabit or have long-term relationships without getting married.
Step-by-step explanation:
An unmarried person is commonly referred to as a bachelor. A bachelor is someone who has never been married. This term is often used for both men and women, although historically it has been more commonly associated with men. It is important to note that being unmarried does not necessarily mean being single or without a partner, as individuals can choose to cohabit or have long-term relationships without getting married.
In the United States, there has been a notable increase in the number of never-married adults, particularly in urban areas like New York City. The decision to marry or remain single can be influenced by a range of factors, including cultural norms, religious beliefs, and personal preferences. By age forty, 20 percent of women and 14 percent of men will have never married. It's also worth noting that some individuals live together without being married, a lifestyle commonly referred to as cohabitation.
