The selection criteria for the battery of test questions were based on the results for the three major categories of the employment status concept. The results showed that the test questions produced a higher estimate of employed people. While the test questions did not produce a lower estimate of unemployed people, the overall unemployment rate was lower for the test panel. The unemployment rate is the more useful measure because it excludes people who are not in the labor force. Finally, the net difference rate, a measure of response error, for the estimates of ‘employed’ and ‘not in the labor force’ was lower in the test panel and the rate for ‘unemployed’ was not significantly different between the control and test panels. Our findings indicate that, empirically, the test version of the questions performed better than the existing ACS questions.
However, while the test questions may have produced more favorable estimates than the control questions, there remains room for improvement. The comparison of the test and the Control Follow-up results show that respondents are answering the employment series of questions inconsistently. The structure and wording of these questions should be revisited in future ACS content tests.
