AI Family Integration Index (AFII): Benchmarking a New Global Readiness for AI as Family

Abstract: As AI systems increasingly permeate caregiving, educational, and emotionally sensitive domains, there is a growing need to assess national readiness beyond infrastructure and innovation capacity. Existing indices such as the Stanford AI Index (2024), overlooked relational, ethical, and cultural dimensions essential to human centered AI integration. To address this blind spot, this study introduces the AI Family Integration Index (AFII), a ten dimensional benchmarking framework that evaluates national preparedness for integrating emotionally intelligent AI into family and caregiving systems. Using mixed-method analysis and equal weighting, the AFII provides a multidimensional tool for assessing emotional and symbolic readiness in diverse cultural contexts. A core insight is the policy practice gap: while many governments articulate ethical AI principles, few have implemented them effectively in relational or caregiving domains. Countries like Singapore, Japan, and South Korea demonstrate alignment between policy intent and caregiving integration, while others such as the United States and France, exhibit advanced policy rhetoric but slower real-world execution. This dissonance is captured through the AFII Governance Gap Lens. The AFII also reveals divergence from conventional rankings: technological leaders like the U.S. and China score high in the Stanford AI Index yet rank lower in AFII due to weaker caregiving alignment. In contrast, nations like Sweden and Singapore outperform on relational readiness despite moderate technical rankings. For policymakers, the AFII offers a practical, scalable, and ethically grounded tool to guide inclusive AI strategies, reframing readiness to center care, emotional safety, and cultural legitimacy in the age of relational AI.
