What is the American Community Survey?
• Meets a critical need for information
• Contributes to better informed decisions
• Helps communities meet the needs of their residents
• Collect detailed decennial census sample data every month instead of only once each decade
• Release tabulations of these data on a yearly basis
• Allow the Census Bureau to restructure and simplify the decennial census effort

What is the American Community Survey?
• A large, continuous survey
– Produces single and multi-year estimates of the characteristics of the population and housing
– Produces characteristics, not a population count
– Produces information for small areas including tracts, block groups and population subgroups
– Key component of the decennial census program

Interpreting the Data: Three Factors to Consider
• Interview and residence rules
• Time periods
• Reference periods
![Page 11: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/11.jpg)

ACS Universe
• Household population of the United States and Puerto Rico
• Household population ONLY in 2005
• Current resident
![Page 12: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/12.jpg)
12
Residence Rules
• Resident of an address if a person– Lives there year round– Lives there more than 2 months but not year
round– Is living there now with no other place to live– Is away now for 2 months or less
• Not a resident of an address if a person– Lives there 2 months or less with another
residence– Is away now for more than 2 months
![Page 13: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/13.jpg)

ACS Produces Period Estimates
• They describe the characteristics of an area over a specific time period
• Contrast with point-in-time estimates that describe the characteristics of an area on a specific date
![Page 14: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/14.jpg)
14
Reference Periods
• ACS uses the interview date as the single reference point, or as the end of a reference period, for all data collection– No specific reference period – Reference period relative to interview
date
![Page 15: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/15.jpg)
15
Data Comparisons
• If comparing 2005 ACS data with data from previous years, note:– Increased sample size, which has an
impact on sampling variability– More geographic areas in 2005
![Page 16: 1 The American Community Survey (ACS) 2005 Data Release.](https://reader036.fdocuments.in/reader036/viewer/2022062407/56649d8b5503460f94a72a12/html5/thumbnails/16.jpg)
