Nonsampling Error: Although every effort (as described in the Data Processing section) is made in all phases of collection, processing, and tabulation to minimize errors, the data are subject to nonsampling errors such as inability to obtain data for every variable from all units in the population of interest, inaccuracies in classification, response errors, misinterpretation of questions, mistakes in keying and coding, and coverage errors.
Overall Unit Response Rate:The overall unit response rate to the 2011 Annual Survey of Local Government Finances was 93.1 percent. In determining the unit response rate, a unit was determined to be a respondent if it provided information on at least one variable or if a CAFR was available. This unit response rate was calculated for each state as well as for the total U.S., and provides the percentage of the units in the eligible universe that actually responded to the survey.
Total Quantity Response Rate: The total quantity response rate was calculated for certain key variables for each state. This response rate is computed separately for each key variable by summing the weighted data provided by the respondents for the key variable using item edit and imputation flags, and dividing this sum by the total estimate (respondents and nonrespondents) for the key variable; the result is multiplied by 100.
Note: The total quantity response rates for 2008-2011 are not comparable to 2007 because 2008-2011 item response status was determined by individual item flags.
