Final answer:
The statement about 10% of people knowing their neighbors cannot be confirmed as true or false without specific statistics. Social studies concepts, such as social disorganization theory and historical social structures, suggest the plausibility but do not provide exact figures.
Step-by-step explanation:
The question at hand addresses a common perception about how well neighbors know each other. While perceived levels of community closeness can affect the fabric of society, there is no definitive statistic provided within the question to categorically state whether it is true or false that about 10% of people know their neighbors and fewer know their last names.
In this context, it's important to reflect on the nuances of neighborhood dynamics and social interactions. For example, the notion of separate spheres and the often citied Cult of Domesticity might provide historical context as to why some social standings might have led to less neighborly interaction, thus implying that the statement could be plausible based on historical social structures.
