This means that today the Mexican health system is beset with inefficiencies and fragmentation, with resources split across multiple independent subsystems. Though coverage and public health expenditure has increased, which should be commended, access to services remains far from equal. Not only are some 21.5% of Mexicans still without health coverage according to survey data (CONEVAL, 2012), but levels of services differ significantly between sub-systems, and accessing care often demands a significant out-of-pocket expense.
