Universal health care, sometimes referred to as universal health coverage, universal coverage, or universal care, usually refers to a health care system which provides health care and financial protection to all citizens of a particular country. It is organized around providing a specified package of benefits to all members of a society with the end goal of providing financial risk protection, improved access to health services, and improved health outcomes. Universal health care is not one-size-fits-all and does not imply coverage for all people for everything. Universal health care can be determined by three critical dimensions: who is covered, what services are covered, and how much of the cost is covered. It is described by the World Health Organization as a situation where citizens can access health services without incurring financial hardship. U.N. member states have agreed to work toward universal health coverage by 2030.
The first move towards a national health insurance system was launched in Germany in 1883, with the Sickness Insurance Law. Industrial employers were mandated to provide injury and illness insurance for their low-wage workers, and the system was funded and administered by employees and employers through "sick funds", which were drawn from deductions in workers' wages and from employers' contributions. Other countries soon began to follow suit. In the United Kingdom, the National Insurance Act 1911 provided coverage for primary care (but not specialist or hospital care) for wage earners, covering about one third of the population. The Russian Empire established a similar system in 1912, and other industrialized countries began following suit. By the 1930s, similar systems existed in virtually all of Western and Central Europe. Japan introduced an employee health insurance law in 1927, expanding further upon it in 1935 and 1940. Following the Russian Revolution of 1917, the Soviet Union established a fully public and centralized health care system in 1920. However, it was not a truly universal system at that point, as rural residents were not covered.
In New Zealand, a universal health care system was created in a series of steps, from 1939 to 1941. In Australia, the state of Queensland introduced a free public hospital system in the 1940s.
