I saw this post on Hacker News and was curious about a dataset that has information about countries and their approach to compulsory teaching of swimming.
There are many datasets about drowning rates (see my comment for links), but I'd like to correlate those to the prevalence of swimming lessons for children, either in schools or otherwise a government initiative. Or, percentages of population that can swim, by age groups if possible.
Any machine readable format (even PDF tables) and any license is fine to get me started.
