Assessing the findings of the survey, "consumers' assessment of current business conditions was slightly less positive than last month," noted Dana M. Peterson, chief economist at the Conference Board. "However, the strong labor market continued to bolster consumers' overall assessment of the present situation. Views of current labor market conditions improved in May, as fewer respondents said jobs were hard to get, which outweighed a slight decline in the number who said jobs were plentiful."
