A social issue is a problem that influences many citizens within a society. It is a group of common problem in present-day society and one that many people strive to solve. It is often the consequence of factors extending beyond an individual's control. Social issues are the source of a conflicting opinion on the grounds of what is perceived as morally correct or incorrect personal life or interpersonal social life decisions. Social issues are distinguished from economic issues; however, some issues (such as immigration) have both social and economic aspects. There are also issues that do not fall into either category, such as warfare.
