Health inequality is defined as:

Health inequality is defined as the uneven distribution of health or health resources. This concept emphasizes that not all individuals or communities have the same access to healthcare, nor do they experience the same health outcomes. Factors contributing to these disparities include socioeconomic status, geographic location, education, and systemic barriers that prevent certain populations from receiving the care they need.

Understanding health inequality is crucial as it sheds light on the social determinants of health and prompts policymakers and healthcare leaders to identify and rectify these disparities to improve overall public health. Addressing health inequalities is essential in developing equitable healthcare systems that serve all populations effectively.

In contrast, the other options do not capture the essence of health inequality. The uniform distribution of health resources implies an equal sharing, which contradicts the very notion of inequality. The ability to access healthcare services focuses solely on access rather than outcomes or distribution, and equal outcomes of healthcare interventions suggests that all interventions yield the same results, which is not the case in real-world scenarios where underlying inequalities persist.
