This report on Michigan's demographics examines the changing composition of Michigan's households and the ramification for Michigan schools. The report states that between 1980 and 2000, Michigan's population grew by 7.3 percent, while the number of households grew by 590,448, or 18 percent. Households are growing faster than the population because of the fragmentation of Michigan families into smaller units, and they are becoming more diverse as the percentage of married couples with children decreases, and households composed of unmarried adults, either single or living with each other, increases. In districts where the number of households without children is increasing, schools may want to consider ways to integrate people into community activities--perhaps expanding the use of school buildings as a community resource. Districts should consider the composition of their communities when seeking support for bond issues or determining how to involve the community in school affairs, or how to link service learning to the residents of the districts. Household composition also has a direct effect on income and how much community members are likely to want to increase their taxes for education programs. (Contains 1 table.)
