Since 1790, the US Census Bureau has performed a decennial count of the US population. The twenty-third United States Census was mailed or delivered in March of 2010 and uses April 1, 2010 as the listed reference point.
Why is the Census important?
It undoubtedly provides an important role in your location intelligent decision-making (the Census is the building block upon which almost all our US PCensus databases are based). However, the 2010 Census Redistricting Data also set the direction for apportioning seats in Congress and distributing $400 billion in federal funding.
Differences from the 2000 Census
Unlike the 2000 Census, the 2010 Census is only provided in short-form, asking 10 basic questions concerning name, gender, age, date of birth, race, ethnicity, relationship, and housing tenure.
In 2000, approximately 16 percent of the population were randomly selected to receive a 40-page long form in addition to the short form, asking a variety of additional questions, regarding income, property values, and transportation to work, among other topics. However, many Americans found filling out the long form to be burdensome and intrusive, and due in part to declining return rates, the census long form will be replaced by the ongoing 26-page American Community Survey (ACS).
What is the ACS?
The American Community Survey is a survey that is sent to a small percentage of the population on a rotating basis. Rather than collecting this data every decade, the ACS is conducted every year. It will provide more current data throughout the decade.
The ACS data is not provided like SF1 or Redistricting data in a single PCensus database, but it has been integrated into Estimates & Projections databases.
In fact, Nielsen began integrating ACS data into their 2010 Pop-Facts data.
