Chapel Hill-Carrboro School District • <br /> For the Chapel Hill-Carrboro School District, the statistical analyses show a weak but <br /> statistically significant relationship between the number of children and the number of <br /> bedrooms, the area, and the housing value. <br /> 1. Residential Type and Number of School Children: Inconclusive Relationship <br /> The number of housing units that were not single family residences built in 1992, 1993, <br /> and 1994 were too few to be used as a representative sample for the statistical analysis <br /> of the relationship between residential type and average number of children. In <br /> addition, all of the apartment units built during the three years of the study were in a <br /> single affordable housing complex, and the majority of duplex units built were in one <br /> retirement community. Although it may be possible to determine a relationship <br /> between housing type and the number of students by using data from all existing <br /> housing units, this would not provide student generation rates for new housing units, <br /> which may differ from older units. • <br /> 2.
