Viewing history as a dynamic sequencing of events at present, the household as a social unit can be viewed as a micro social space moving from one point in time to another. Under each of these time points, a household is characterized by a particular structure, content, and size. Each of these time points parallels the stages that a household undergoes which we call developmental cycle stage. This paper tests one major hypothesis that over time, a household productivity pattern increases and fluctuates. The increment and fluctuation are a function of the developmental stages of a household, among other factors.
