Presentation Transcript


The American Community Survey (ACS) 2005 Data Release


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


ACS Universe

  • Household population of the United States and Puerto Rico

  • Household population ONLY in 2005

  • Current resident


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


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


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


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
