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
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
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
