It'll be really interesting to see the sleep data compared against other countries or continents. Sex and age is interesting but you can't tell much from this data. Could comparing it with other countries correlate with a country's economy, culture, general state of affairs? Also, if there is a year to year trend cross reference with country.

If this data is accurate, it could be useful in determining a country's future economics. Ie. perhaps a general population's 5 mins of average less sleep means more stress which means more economic downturn/changes?
