Public expenditure in health care has accounted for a rising proportion of national income in the current and previous centuries and this is regardless of their level of economic development. In this context, the central idea of the paper is to analyze the degree and volume of public health financing systems in developing countries [lower and middle-income countries (LMICs)] with a focus on India. The indicators selected include per capita income of the country (in PPP USD terms), life expectancy at birth (LEB) of the total population, infant mortality rate (IMR), the share of total health care expenditure (THE) as a proportion of GDP, government health expenditure (GHE) as a proportion of total health care expenditure (THE), private health expenditure (PHE) as a proportion of total health care expenditure (THE), etc. A positive relationship between the per capita income of the country and its corresponding health care resource commitment. In average terms, public sources contribute 45 percent of health financing, while the rest is by private means. Countries like Afghanistan, Bangladesh, India, Nepal, Seira Leone spend relatively low from public sources. Life expectancy is having a positive relationship with total health care spending in the countries analyzed. Given the context of serious market failures and government failures, the low-income country populations are in a vicious cycle of ill-health and poverty. Public spending is a major way of removing the clutches of deprivation. Scholars suggest that rich people gain more from public subsidies in education and health than do poor people for four sets of reasons: private costs, differential costs and benefits, patterns of government expenditure, and rationing.
