In Mexico, social security covers more than half the population. Second, those not covered by health insurance have open access to a public provider network, financed out of general taxation. This appears to be the case particularly in India, where the public health infrastructure is underdeveloped, and, given that health expenditures are decentralised at the state/local level, very inequitably shared across states and regions (PricewaterhouseCoopers, 2007). But lack of physical access in some regions is observed in many countries.
