Variable Types

ACS data contain variables ending in E, EA, M, MA, PE, PM and SS. See the table below for each variable type and its meaning:

Variable Type Title Related Products Meaning
E Estimate Summary Files, Subject Tables, Data Profiles, Comparison Profiles A numeric representation of the estimate.
EA Estimate Annotation Subject Tables, Comparison Profiles A character representation of the estimate. If an Estimate Annotation exists, use this value in place of the Estimate.(See Example #1 in Estimate and Annotation Values)
M Margin of Error Summary Files, Subject Tables, Data Profiles A numeric representation of the margin of error.
MA Margin of Error Annotation Subject Tables Only A character representation of the margin of error. If a Margin of Error Annotation exists, use this value in place of the Margin of Error.
PE Percent Estimate Data Profiles Only An estimate representing a percent of the total.
PM Percent Margin of Error Data Profiles Only The Margin of Error for the corresponding Percent Estimate (PE) variable
SS Statistical Significance Comparison Profiles Only Returns ‘*’ or ‘c’ representing the Statistical Significance for the corresponding estimate (E) variable. (See Example #2  in Estimate and Annotation Values)

An * indicates that the estimate is significantly different (at a 90% confidence level) than the estimate from the most current year. A "c" indicates the estimates for that year and the current year are both controlled; a statistical test is not appropriate.
