2. The Decennial Census • Longest running federal data collection program in the United States (since 1790) • Census collects basic population counts as well as a wide variety of housing, household, and some basic economic data. (Plumbing data, too!!) • The census provides a “snapshot” of the US population at a certain time (say, the population in 2000).

3. Why is the Census So Important? 1) Required by the ConstitutionIt is how we delineate local voting districts and districts for the House of Representatives in Congress 2) Political PowerIt is how local redistricting for elected offices is done, 3) Money, Money, and more Money!!! Estimated that over $200 billion will be distributed annually based upon 2000 Census data 4) A Rich and Heavily Used Data SetThe data are used by planners, other local government officials, researchers, marketers, for a huge variety of things.

4. Census BIG Points • A wealth of data available through the Census. • Knowing where to get the data and what you are actually getting is the key. • It is best to have an idea of what you want before you attempt to go get the data. Blind searches usually lead to frustration. • A good understanding of the Census Bureau and Census data is a real planning skill. The BIG Point: Census data often represents the starting point for planning-related work. After acquiring Census data, only then is additional data gathered to build upon the general population, housing, and economic data the Census collects and makes available.
