Denmark, which has the highest proportion of happy seniors, mitigates stratification by income by providing:

Denmark's approach to supporting its senior population is reflected in its provision of free health care and subsidized senior housing. These measures are instrumental in mitigating income stratification among older adults, ensuring that all seniors have access to essential health services and affordable living conditions, regardless of their income levels.

Free health care allows seniors to receive necessary medical attention without the burden of high costs, which can be particularly concerning for those with fixed or limited incomes. This universal access helps promote overall health and well-being among seniors, contributing to their happiness and quality of life.

Subsidized senior housing further alleviates financial stress by enabling older adults to live in suitable and safe environments that they can afford. This not only fosters a sense of security but also enhances their social integration, as they often live in communities designed to support seniors' needs.

By combining these two significant factors, Denmark effectively reduces the disparities in welfare that can arise from financial inequities, thereby promoting a happier and healthier population of seniors.
