The Census Bureau has changed the way it conducts the national count.
In the past, most households received a short-form questionnaire, while one household in six received a long form that contained additional questions and provided more detailed socioeconomic information about the population.
Beginning in 2010, the decennial census will be a short-form only census and will count all residents living in the United States as well as ask for name, sex, age, date of birth, race, ethnicity, relationship and housing tenure - taking just minutes to complete.
The more detailed socioeconomic information is now collected through the American Community Survey. The survey provides current data about your community every year, rather than once every 10 years. It is sent to a small percentage of the population on a rotating basis throughout the decade. No household will receive the survey more often than once every five years.
