  1. Census Data-Strictly Business?: What’s Different about Census 2010 (and on)? What’s “New” late 2010-2012?— what’s in there and what’s not in there? Access Points & Methods—demos Q & A (ask at anytime) Jim Skinner- Research Division Atlanta Regional Commission jskinner@atlantaregional.com

  2. Decennial Census in the recent past… • In Census 2000, the census used 2 forms • “short” form – asked for basic demographic and housing information, such as age, sex, race, how many people lived in the housing unit, and if the housing unit was owned or rented by the resident (SF1 and SF2) • “long” form – collected the same information as the short form but also collected more in-depth information such as income, education, and language spoken at home (SF3..and SF4) • Only a small portion of the population, called asample, received the long form. 1 IN 6 IN 2000 2

  3. 2010 Census and American Community Survey • 2010 Census focused on counting the U.S. population • The sample data are now collected in the ACS. There is no more “long-form” (no more SF3 or SF4) • Same “short form” questions on the ACS • 5-year estimates will be produced for same broad set of geographic areas including census tracts and block groups 3

  4. American Community SurveyKey Differences from Census 2000 • The goal of ACS is to produce data comparable to the Census 2000 long form data • These estimates will cover the same small areas as Census 2000 but with smaller sample sizes • Smaller sample sizes for 5-year ACS estimates results in reductions in the reliability of estimates 4

  5. Population Thresholds for ACS Estimates
