Final answer:
In sociology, 'family' is defined as a group with emotional and economic ties, with two main types being the family of orientation (birth family) and family of procreation (established through marriage).
Step-by-step explanation:
The concept of family has evolved over time, being a subject of extensive discussion in sociology, politics, and religion. While there are many ways to define 'family', sociologists commonly refer to it as a socially recognized group that forms an emotional connection and functions as an economic unit within society. This can include various bonds such as blood, marriage, cohabitation, or adoption. Two main types of families identified by sociologists are the family of orientation and the family of procreation. A family of orientation refers to the family in which a person is born and raised, typically involving parents and siblings. Conversely, a family of procreation is one that a person establishes, often through marriage and includes one's spouse and children. It's important to distinguish these terms, as they have cultural and societal implications, especially when considering issues of lineage and descent.
