Published by the Census Bureau, the 2004-2005 edition is now available online. This JUICY publication provides statistical tables and charts covering various aspects of social, political, and economic life. Emphasis is on the United States, but some tables cover comparative international statistics. Information is gathered from all agencies of the federal government and from private, commercial, and professional sources. This is a great read, for substantive information and trivia alike.
