Churches. A significant percentage of the population of Taiwan is non-religious. Taiwan's lack of state-sanctioned discrimination, and generally high regard for freedom of religion or belief earned it a joint #1 ranking in the 2018 Freedom of Thought Report, alongside the Netherlands and Belgium. On the other hand, there have been instances of the Indonesian migrant worker community in Taiwan (estimated to total 258,084 people) experiencing religious restrictions by local employers or the government. LGBT rights On 24 May 2017, the Constitutional Court ruled that then-current marriage laws had been violating the Constitution by denying Taiwanese same-sex couples the right to marry. The Court ruled that if the Legislative Yuan did not pass adequate amendments to Taiwanese marriage laws within two years, same-sex marriages would automatically become lawful in Taiwan. In a referendum question in 2018, however, voters expressed overwhelming opposition to same-sex marriage and supported the removal of content about homosexuality from primary school textbooks. According to the New York Times, the aforementioned referendum questions were subject to a "well-funded and highly organized campaign led by conservative Christians and other groups" involving the use of "misinformation, the bulk of which was spread online." Nevertheless, the vote against same-sex marriage does not affect the court ruling, and on 17 May 2019, Taiwan's parliament approved a bill legalising same-sex marriage, making it the first country in Asia to do so. Taiwan has an annual pride event, Taiwan Pride. It currently holds the record for the largest LGBT gathering in East-Asia, rivaling Tel Aviv Pride in Israel. The event draws more than 200,000 people to demonstrate for equal rights for LGBT people. The event is organized by the Taiwan LGBT Pride Community, and is held on the last Sunday of October. Health The current healthcare system in Taiwan, known as National Health Insurance (NHI, ), was instituted in 1995. NHI is a single-payer compulsory social insurance plan that centralizes the disbursement of healthcare funds. The system promises equal access to healthcare for all citizens, and the population coverage had reached 99 per cent by the end of 2004. NHI is mainly financed through premiums, which are based on the payroll tax, and is supplemented with out-of-pocket co-payments and direct government funding. Low-income families, veterans, centenarians, children under three years old, and catastrophic diseases are exempt from co-payments. Co-pays are reduced for disabled and low income households maintain 100 percent premium coverage by
