The agency cited a survey of single people aged 25 to 34, showing that 43.3% of men and 48.1% of women said they had no opportunity to meet potential partners in 2021. Many said they had not done anything to increase their chances, such as attending matchmaking events or asking friends for introductions. Because comparatively few children are born to unmarried people in Japan, the decline of marriage has been cited as a significant reason for its low birthrate and dwindling, ageing population. In 2023, marriages dropped below 500,000 for the first time since the 1930s. Meanwhile, births dropped 5.1% to 758,631, a new record low and almost reaching 755,000, a figure the National Institute of Population and Social Security Research had predicted for 2035.
