Kids today. They have no sense of shame. They have no sense of privacy. They are show-offs, fame whores, pornographic little loons who post their diaries, their phone numbers, their stupid poetry—for God’s sake, their dirty photos!—online. They have virtual friends instead of real ones. They talk in illiterate instant messages. They are interested only in attention—and yet they have zero attention span, flitting like hummingbirds from one virtual stage to another.

Ouch.  It’s certainly harsh but is it accurate?

The ARDA allows you to interactively explore the highest quality data on American and international religion using online features for generating national profiles, maps, church membership overviews, denominational heritage trees, tables, charts, and other summary reports. Over 350 data files are available for online preview and most can be downloaded for additional research.

It has a wealth of data and features, but along with the Quickstats section, one of the more useful is the ability to compare statistics for different nations. For example, here is a comparison of Saudi Arabia and Australia.
