Although research on caregivers to impaired elderly is accumulating rapidly, most prior studies are small area analyses of non-probability samples. This study adapts a secondary but nationally representative data base to construct statistical profiles of intrahousehold caregivers in three types of households. The potential for disruption of each type of caregiving arrangement is examined in terms of the care needs of the older person and the competing demands on the caregivers. Situations where care is provided to a dependent, unmarried relative appear to be most vulnerable to dissolution.
