family不包含单身。 丁克算。 两个人以上就算了，只要有婚姻血缘关系都算。兄弟姐妹也算。 下面是美国人口普查的官方定义。 不知道美国有没有哪些地方household高于family income的。这个地方应该有很多钻石王老五, 或者很多纯朋友群居。
A family consists of two or more people (one of whom is the householder) related by birth, marriage, or adoption residing in the same housing unit. A household consists of all people who occupy a housing unit regardless of relationship. A household may consist of a person living alone or multiple unrelated individuals or families living together.
