Final answer:
The unemployment survey is criticized for not including discouraged workers who have stopped job searching and over including individuals who claim to be seeking work but are not earnestly doing so, which affects the accuracy of unemployment data.
Step-by-step explanation:
The two main criticisms of the data collected in the unemployment survey relate to the exclusion of discouraged workers and the inclusion of those who may not be truly seeking employment. Discouraged workers are those who have stopped looking for work due to the perception that no jobs are available for them. These individuals are technically unemployed, but are not counted as part of the labor force because they are not actively seeking employment. This can understate the true measure of joblessness. On the other hand, some individuals may claim they are actively looking for work when in reality, they are not diligently seeking employment. These individuals are counted as unemployed, potentially overstating the true level of unemployment. Furthermore, there are individuals who have informal employment, like yard work or childcare, who do not report their income, and may declare themselves unemployed despite actually working.
