The correct answer is Divorce occurs more frequently at the lower socioeconomic levels.
Divorce is the action and effect of divorcing (dissolving a marriage legally, separating or separating people or things that were together).
Most western countries consider marriage to be a union between two people with legal, social and cultural recognition. Its objective is to offer a scope of mutual protection and of the offspring of the two people, who have rights and obligations for this union.
Divorce, therefore, is the legal or religious dissolution of marriage by agreement between both parties or by the violation of any of the rights or obligations of marriage. Legislation usually protects children born during the dissolved bond as well as women.
When the law or religion does not allow divorce, the separation occurs, with no other remedy than the dissolution of the relationship and the removal of the couple.
Divorced people used to be socially condemned, as the belief in marriage for life was very strong. In recent decades, however, this concept has changed and now divorce is accepted as a natural situation for relationships that have not worked.
