Final Answer:
According to the Census Bureau's definition, 3) Two unrelated individuals living together is not considered a family.
Step-by-step explanation:
The Census Bureau's definition of a family is based on the concept of related individuals living together, typically by blood, marriage, or adoption. In this context, option 3, "Two unrelated individuals living together," does not meet the criteria for a family as defined by the Census Bureau.
The bureau focuses on relationships that involve a familial connection, excluding unrelated individuals residing together from the classification of a family. This distinction is essential for accurate demographic and social data collection, as it helps categorize households based on familial ties and relationships.
In summary, the correct answer is 3) Two unrelated individuals living together is not considered a family according to the Census Bureau's definition.
