Anyone can be lonely at any stage of life, and most people will experience loneliness at some point. That said, there are some groups that are more likely to be lonely than others.
One study found that men are more likely to be lonely than women, with 63% of men reporting loneliness compared with 58% of women.
Another study found that women were more likely to report loneliness, but only due to a reluctance to report among men.
Other research uncovered that younger people (aged 16-24) report more loneliness, although the negative consequences of loneliness are often much more serious for the elderly.
