But before we begin, here’s how the best destinations were identified. Prudential ranked 55 counties in England and Wales based on nine key factors. These were the size of the pensioner population living in the area, the number of pensioners moving there, access to healthcare, crime levels, healthy lifestyle data, pension income, disability-free life expectancy, weather and happiness. Counties were ranked for each category out of 55, and these were tallied to give an overall score.
