The People pillar of the 2030 Agenda for Sustainable Development focuses on quality of life in all its dimensions, and emphasises the international community’s commitment to ensuring all human beings can fulfil their potential in dignity, equality and good health. Thailand’s path from a low-income to an upper-middle-income country over recent decades is widely hailed as a development success story. Poverty has fallen impressively and inequality is on a downwards trend, but more efforts are needed to reduce still widespread informality and persistent, substantial regional inequalities, and to further improve living standards, especially for those who currently work informally. To achieve these objectives, the government needs to: (i) consider tax and regulatory measures to encourage formalisation; (ii) boost the participation rates of informal workers in social protection schemes; (iii) expand adequate social safety nets for poor households and the elderly; (iv) prepare the healthcare system for an ageing and modernising society; and (v) improve the education system, particularly in rural areas. Gaps also remain in ensuring women’s political participation and reducing gender-based violence.
