1. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science Census to American Community Survey

2. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science Decennial Census  In Census 2000, the census used two forms 1.“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 2.“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  Only a small portion of the population, called a sample, received the long form.

6. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Similarities with Census 2000  Same Questions and many of the same basic statistics  5-year estimates will be produced for same broad set of geographic area including census tracts and block groups

7. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Data from the ACS can be grouped into four categories  Demographic  Social  Economic  Housing

17. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Methodology  Sample includes about 3 million addresses each year  Three models of data collection: 1. Mail 2. Phone 3. Personal Visit  Data are collected continuously throughout the year  High levels of quality have been demonstrated

18. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Period Estimates  ACS estimates are period estimates describing the average characteristics over a specified period  Contrast with point-in-time estimates that describe the characteristics of an area on a specific date  1-year, 3-year, and 5-year estimates will be released for geographic areas that meet specific population thresholds

19. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science Questions with no specific reference period  Most ACS questions do not stipulate a period of time that should be referenced  Interpretation is yearly average since the data are collected each month and averaged across months

20. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science Questions with a specific reference period relative to interview date  Other questions specify a period of time relative to the date of interview  Interpretation is still a yearly average but covering a slightly different period of time than the calendar year

23. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science What is Sampling Error? Definition The uncertainty associated with an estimate that is based on data gathered from a sample of the population rather than the full population

24. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science What is Non-Sampling Error? Definition: Any error affecting a survey or census estimate apart from sampling error Occurs in complete censuses as well as in sample surveys

25. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science Types of Non-Sampling Error  Non-Response Error  Response Error  Processing Error  Coverage Error

26. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Key Differences from Census 2000  Beginning in 2010, data for small geographic areas will be produced every year versus once every 10 years  Data for larger areas are available now and data for mid size area will be available in December 2008  Census 2000 data describe the population and housing as of April 1, 2000 while the ACS data describe a period of thime and require data for 12 months, 36 months, or 60 months

27. THE UNIVERSITY OF MISSISSIPPI The University of Mississippi Institute for Advanced Education in Geospatial Science American Community Survey: Key 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
