Addressing the long-term care (LTC) needs of the elderly as families’ capacity for caregiving decreases is both a policymaking priority and societal challenge facing many countries around the world. Care for older people relies heavily upon informal caregivers, traditionally women in the family. However, a growing role can be seen for formal services—either in place of or in conjunction with informal carers—made available by state, societal, or private market actors. This mix of formal and informal care arrangements, carried out by public and private actor types with varying degrees of engagement across a range of care settings can be said to come together to form an “eldercare regime.” In this chapter, the authors unpack the concept to understand the various ways that care manifests within and across societies. The focus is particularly on public versus private responsibility, as well as the intersections between the formal and informal within the care mix. The chapter proceeds to take inventory of care arrangements in place in different countries across Europe, North America, and Asia in which public LTC services and/or benefits have been introduced. The analysis demonstrates that, even among countries in which publicly financed care is available, a wide range of care constellations and actor emphases can be observed, culminating in distinct eldercare regimes. In a final section, the chapter explores differences between countries in financing, services provision, and regulation with respect to tradition, interdependencies with other areas of the welfare state, and normative standards.
