What would probably occur from under coverage?

Undercoverage occurs when certain groups in a population are inadequately represented in a survey or study, leading to biased results. This can result in inaccurate conclusions, as the findings may not reflect the true characteristics or opinions of the entire population. Consequently, policies or decisions based on such data may be misguided, potentially exacerbating inequalities and failing to address the needs of underrepresented groups. Overall, undercoverage undermines the validity and reliability of research outcomes.
