From 1970 to 2021, the United Nations diligently collected data on marital status, encompassing approximately 1.6 billion individuals globally. Within this vast dataset, singles are defined as individuals who are unmarried, divorced, separated, or widowed. This comprehensive collection of marriage data sheds light on the significant number of people across the globe who identify as single, providing valuable insights into societal trends and demographic dynamics. Throughout this period, the UN's commitment to gathering and analyzing such data has facilitated a deeper understanding of the prevalence and distribution of singles worldwide, including in the diverse and dynamic region of Southeast Asia.
