These websites offer views of US Census data:
Published annually by the Federal Government since 1878, the Statistical Abstract of the United States is the best-known statistical reference publication in the country, and perhaps, the world. You’ll find it behind nearly every reference desk in U.S. libraries as the authoritative go-to source. Librarians value the Statistical Abstract as both an answer book ("How much corn is grown in Iowa?") and a guide to statistical sources ("What organization has the most authoritative data on foreclosures?"). As a comprehensive collection of statistics on the social, political, and economic conditions of the United States, it is a snapshot of America and its people.
