The United States healthcare system, serving some 308,745,538 people (2010), is the most expensive health system in the world. Care costs more per person, and consumes a greater portion of GDP per person each year, than all United Nations members except for East Timor (Timor-Leste). Additionally, the United States ranks last in the quality of health care among developed countries when considering infant mortality and life expectancy--the most widely collected healthcare data globally. On March 23, 2010, President Barak Obama signed into law the Patient Protection and Affordable Care Act in addition to the Health Care and Education Reconciliation Act of 2010 (March 30), producing in sum the health care reform efforts of the Democratic 111th Congress and the Obama administration. Citizen rights, access, quality and affordable healthcare remains contested.
