As life expectancy increases, the proportion of adults in their retirement years is expected to grow in all regions of the world. According to recent data, there are approximately 901 million people worldwide who are 60 and over. By 2050, that number will reach 2.1 billion people, or 21.5 percent of the global population.
But the experiences people have later in life vary greatly depending on where they live.
The Global AgeWatch Index recently assessed 96 countries to determine the best places for older adults to live. These countries include more than 90 percent of the world's population aged 60 and over.
The rankings were based on how well each country scored in four categories: older adults' health status, income security, capability (measured by employment status and education levels), and enabling environment (measured by access to public transportation, physical safety, social connections and civic freedom).
