American Community Survey
"The American Community Survey is a new nationwide survey designed to provide communities a fresh look at how they are changing. It is a critical element in the Census Bureau's reengineered 2010 census plan." This survey provides data on an ANNUAL basis and will replace the long census form in 2010. In essence, we will have continually updated census data in the future, not just every 10 years."
