Recent global health data for 2026 suggests that the United States often reports the highest levels of sleep-related issues and economic loss due to insufficient sleep, with nearly 30% to 40% of adults experiencing insomnia symptoms annually. However, when looking specifically at clinical diagnosis and chronic sleep disorders, the Netherlands and Italy (specifically the South Tyrol region) report very high percentages of residents who do not get adequate rest. In Asia, China reports that over 300 million of its citizens suffer from sleep disorders, fueled largely by high-pressure work cultures and urbanization. Culturally, the "most insomnia" can be difficult to pin down because definitions of "poor sleep" vary, but industrialized nations with high levels of screen time and late-night work culture consistently top the list. For your database project, it's worth noting that women are statistically twice as likely as men to experience insomnia worldwide, a trend that remains consistent across nearly all surveyed countries.
