If you’re as fond of numbers as I am you could get lost for
hours exploring the Fedstats (http://fedstats.sites.usa.gov/)
website or the CDC’s data & statistics website (http://www.cdc.gov/DataStatistics/). With the Fedstats site I found myself
wandering into the data releases section and then on into interesting looking
sub-agencies to look at actual numbers.
With the CDC I of course focused on cancer (my niece has leukemia so
there’s a little personal interest there).
In any event both sites provide a plethora of data to look at. Enjoy.
