What is the American Community Survey?What is the American Community Survey?
A large, continuous survey that: is sent to 3 million resident addresses per year
produces characteristics of population and housing
produces estimates for small areas and small population groups
Produces characteristics, not a population count
Key component of the decennial census program

Continuous measurement conceptualized
Congress renewed interest in an alternative to the once-a-decade census
Work began on what evolved into the ACS
First operational test conducted in 4 sites
Test sites expanded yearly to 36 counties in 26 states

Developing the ACSDeveloping the ACS
The ACS was developed to:
1. Focus the 2010 Census on improving the population count
2. Provide characteristic data more than once every 10 years to frame policy issues
3. Allow use of current data to respond to new trends
2010 Census and the ACS2010 Census and the ACS
2010 Census ACS
• U.S. population count • U.S. population characteristics
• Short form only • Includes short form questions
• Only long form is for U.S. territories, except Puerto Rico
• Conducted in Puerto Rico
• “Usual residence” rule • “Current residence” rule

ACS Sample DesignACS Sample Design
Sample is accumulated over TIME to produce lowest levels of geographic detail to replace census sample
5 years of data are required for areas and population groups with less than 20,000 population
Sample cases selected from an updated Master Address File (MAF)
15
SampleSample
Questionnaires mailed to about 1 in 480 addresses each month throughout the U.S. and Puerto Rico.
1 in 40 addresses per year (2.5% of the population). Average of 500-600 addresses per month per
congressional district. Total of 3 million addresses each year, or 250,000
per month. Inclusion of population in group quarters beginning
in 2006.
16
Target PopulationTarget Population
Resident population of the United States and Puerto Rico
Living in housing units and group quarters (group quarters added in 2006)
Current residents at the selected address
17
Methodology Methodology
Sample includes about 3 million addresses each year
Three modes of data collection– mail– phone– personal visit
Data are collected continuously throughout the year
18
Period EstimatesPeriod Estimates Describe the average characteristics over a specific period of time
Contrast with point-in-time estimates -- Do not describe the characteristics on a specific date
Period is 1 year, 3 years, or 5 years for ACS
1 Year Estimates Geographic areas with 65,000 or more population
3 Year Estimates Geographic areas with more than 20,000 population
5 Year Estimates All geographic areas down to the census tract & block group level
19
Geographic BoundariesGeographic Boundaries Multiyear estimates are based on geographic
boundaries as of January 1 of the last year in the multiyear period
Example: 2007-2009 ACS estimates use boundaries as of Jan 1, 2009Boundary Annexation Survey collects boundary Boundary Annexation Survey collects boundary
changeschanges
Boundaries of other statistical areas will be updated every decade in conjunction with the decennial census
2010 Census boundaries will be used for data released in 2011

American Community Survey GeographyAmerican Community Survey Geography
The 2010 ACS data release marks the first time ACS will
use 2010 tabulation geography for most statistical areas, the same definitions as the 2010 Census.
Geographic areas whose definitions were updated for the 2010 Census include Census Designated Places (CDPs), census tracts, and block groups.
2010 ACS estimates for PUMAs and urban areas continue to use Census 2000 definitions.

EstimatesEstimates
ACS data are estimates
ACS data are not counts of the population or housing
Population counts are produced from the decennial census
- Counts are updated throughout the decade through the Population Estimates Program
26
Margin of Error (MOE)Margin of Error (MOE)
Margin of Error Definition: A measure of the precision of an estimate at a given level of confidence (90%, 95%, 99%) -- MOEs at the 90% confidence level for all published ACS estimates
Confidence Interval Definition: A range that is expected to contain the population value of the characteristic with a known probability
Margin of ErrorMargin of Error
28
Inflation AdjustmentInflation Adjustment
Dollar-valued data items are inflation adjusted to the most recent year for the period
Income, rent, home value, and energy costs
Adjusted using inflation factors based on the Consumer Price Index (CPI)
Adjustment designed to put the data into dollars with equal purchasing power
29
Population ControlsPopulation Controls
Estimates of housing units and people are controlled to the population estimates derived from the Population Estimates Program
Multi-year estimates are controlled to the average of the individual year’s estimates for the period
Change in Population ControlsChange in Population ControlsThe 2009 ACS and 2010 ACS 1-year estimates use different Census base years for the population estimates used in the ACS weighting. As a result, users should use caution when making comparisons across years. Specifically, estimates of the number of people in a given location (population size) are not strictly comparable between these two years. In general, the change to more current population estimates is not expected to have a meaningful impact in the percent distributions, rates, or ratios for non-demographic characteristics for many of the largest geographic areas. The Census Bureau is currently researching the effect on these distributions. For more details, visit the ACS Research Note Change in Population Controls.
