Abstract
This quantitative study employed a survey research design to investigate the intricate relationship between income levels and health expenditures in Nigeria. A structured questionnaire was meticulously designed to gather data from a diverse sample of 120 respondents, offering insights into their health expenditure patterns, income levels, and perceptions of financial protection in healthcare. The survey methodology facilitated the collection of numerical data, aligning to quantify the identified relationships. Data analysis was conducted using SPSS27, a robust statistical software known for its versatility in quantitative data analysis. The software enabled the exploration of relationships between variables, including the examination of income elasticity of health expenditures. A one-sample t-test, assuming a mean of 0, was employed to test the hypotheses formulated in the study. Notably, all null hypotheses were rejected, indicating significant relationships between income levels and health expenditures, factors influencing health expenditures, and the role of financial protection in health expenditures. The findings revealed that individuals with varying income levels exhibit distinct health expenditure patterns, emphasizing the need for targeted health policies. Additionally, the study underscored the role of financial protection mechanisms, such as health insurance, in mitigating the economic burden of healthcare costs for individuals with low incomes. Increased government spending on health emerged as a crucial factor in enhancing healthcare access and affordability across income groups. In conclusion, this study contributes valuable insights to the field of global health economics, specifically within the context of Nigeria. The quantitative survey design, coupled with the use of SPSS27 and the application of a one-sample t-test, ensured a rigorous examination of the research questions. The rejection of null hypotheses provides compelling evidence for the existence of significant relationships, guiding the formulation of recommendations. Recommendations derived from the study include the crafting of tailored health policies, enhanced financial protection mechanisms, increased government investment in healthcare, and collaborative efforts between the public and private sectors. These recommendations aim to address disparities in health expenditures and contribute to the overall improvement of healthcare accessibility and quality in Nigeria.

INTRODUCTION
Background to the Study
In the realm of global health economics, the intricate relationship between income levels and health expenditures has been a subject of significant discourse (Abu & Abdullahi, 2020). The allocation of financial resources to health-related services is a critical determinant of the population’s well-being, influencing the accessibility and quality of healthcare services. This dynamic relationship has profound implications for both developed and developing nations alike. In the context of Nigeria, a country marked by economic diversity and a dynamic healthcare landscape (Bakare & Olubokun, 2021), understanding the income elasticity of health expenditures becomes imperative for effective policymaking and resource allocation.
Nigeria, the most populous country in Africa, faces a myriad of health challenges ranging from infectious diseases to non-communicable ailments (Olatubi et al., 2018). The burden of diseases places considerable strain on the country’s healthcare system and necessitates a strategic approach to health expenditure. Against this backdrop, the government and other stakeholders are continually engaged in efforts to optimize health expenditure (Adelakun, 2021). Recognizing the pivotal role that health expenditure plays in fostering a healthier population, there is a growing awareness of the need to tailor health policies to the specific needs of the diverse Nigerian population.
The income elasticity of health expenditures in Nigeria is a crucial parameter to understand the responsiveness of health spending to changes in income levels over time (Abu & Abdullahi, 2020). This relationship is particularly significant in a country where economic disparities are prevalent. A comprehensive analysis of the income elasticity of health expenditures allows policymakers to gauge the degree to which health spending adjusts in response to fluctuations in income. This understanding is fundamental for designing policies that ensure equitable access to healthcare services for individuals across various income groups.
The government’s role in optimizing health expenditure is central to achieving sustainable health outcomes (Adesoye et al., 2020). Policies that foster economic growth and development can positively impact the overall health of the population (Olubokun & Bakare, 2021). Investments in education, human capital development, and poverty alleviation programs can contribute to an improvement in income levels, subsequently influencing health expenditures. As demonstrated by studies such as that of Adamu (2021), which explores the impact of human capital on economic growth in Nigeria, there is a clear link between educational attainment and economic development. The knowledge and skills acquired through education can empower individuals to participate more effectively in the workforce, leading to increased income levels and, consequently, higher health expenditures.
Furthermore, the factors influencing health expenditures in Nigeria are multifaceted and require a nuanced approach. Studies such as that conducted by Oisaozoje and Opusunju (2016) emphasize the importance of human capital development in influencing economic growth and, by extension, health expenditures. Human capital development encompasses education, skills training, and healthcare, all of which contribute to a healthier and more productive population. These factors, when adequately addressed, can positively influence health expenditures by reducing the prevalence of diseases, improving overall well-being, and mitigating the economic burden of healthcare.
Financial protection mechanisms play a crucial role in stabilizing health expenditures, especially in the face of income fluctuations (Oladeji, 2015). The establishment and enhancement of health insurance schemes and social assistance programs contribute to shielding individuals from the financial burden associated with healthcare costs (WHO, 2019). These mechanisms act as a safety net, ensuring that individuals can access essential healthcare services without facing catastrophic financial consequences. As demonstrated by Clements et al. (2021), the financial architecture surrounding healthcare can significantly impact the overall efficiency and effectiveness of health expenditures.
Consequently, the intricate relationship between income levels and health expenditures in Nigeria underscores the need for a comprehensive understanding of the income elasticity of health expenditures. The country’s economic diversity, coupled with a dynamic healthcare landscape, necessitates targeted policies that consider the specific needs of various income groups. By exploring the factors influencing health expenditures and evaluating the role of financial protection mechanisms, this research contributes to the ongoing discourse on health economics in Nigeria. Policymakers can leverage these insights to formulate strategies that optimize health expenditure, ultimately fostering a healthier and more resilient population.
 Statement of Problem
In the context of Nigeria’s complex healthcare landscape, the income elasticity of health expenditures emerges as a critical concern (Abu & Abdullahi, 2020). The nation grapples with a diverse range of health challenges, from infectious diseases to non-communicable ailments (Oisaozoje & Opusunju, 2016), putting immense pressure on the healthcare system. As the most populous country in Africa, the demand for healthcare services is substantial, and understanding how health expenditures respond to changes in income is essential for effective resource allocation (Bakare & Olubokun, 2021).
The problem at hand is compounded by economic disparities across various regions and income groups in Nigeria (Adelakun, 2021). The unequal distribution of wealth and income inequality present significant challenges in ensuring equitable access to healthcare services. It raises questions about the extent to which different income groups can afford and access essential healthcare, and how variations in income levels impact overall health expenditures.
Furthermore, the lack of a comprehensive understanding of the income elasticity of health expenditures hampers the formulation of targeted health policies (Adesoye et al., 2020). Without a nuanced grasp of how health spending adjusts to changes in income over time, policymakers may struggle to design effective strategies for optimizing health expenditure. This knowledge gap poses a barrier to achieving sustainable health outcomes and may hinder progress towards the broader goal of improving the overall health of the population (Olubokun & Bakare, 2021).
Financial protection mechanisms are critical in addressing the economic burden associated with healthcare costs, but the effectiveness of such mechanisms in the Nigerian context remains unclear (Clements et al., 2021). The statement of the problem, therefore, revolves around the need to comprehensively investigate the income elasticity of health expenditures in Nigeria, considering the diverse economic landscape, and to assess the role of existing financial protection mechanisms in ensuring equitable access to healthcare across different income groups. This research gap hinders the development of informed policies that can effectively address the intricate relationship between income levels and health expenditures in Nigeria.
