Every year on July 11, World Population Day draws attention to the demographic trends reshaping societies around the globe. In 2026, the United Nations marks the occasion under the theme, "Realizing the Hopes and Aspirations of Young People – Today and for the Future," highlighting how young people's decisions about education, employment, housing, relationships, and family life are increasingly influenced by the cities they inhabit. Drawing on Lives, Choices and Futures, a global survey of more than 108,000 young adults across 73 countries, this year's campaign underscores the close relationship between demographic change and the social, economic, and spatial conditions of cities.
In South China, there is occasionally an urban myth—especially across Hong Kong, Shenzhen, and Guangzhou—about choosing a home that avoids western light. Over decades, the west-facing sun has proven to be a particularly difficult condition to live with: its low angle in the afternoon, its aggressive heat gain (especially in summer), and the way it penetrates deep into interiors. With global warming and longer, hotter seasons, that much-romanticized "afternoon glow" is increasingly experienced less as romance and more as glare, heat, and fatigue. Although this wisdom circulates as a community-driven rule of thumb, it carries an undeniable architectural clarity about building orientations: avoiding western light is not only about thermal comfort, but also about avoiding the sharpest, most intrusive form of direct illumination—light that strikes at the most unforgiving angle, washing surfaces, flattening depth, and turning rooms into high-contrast fields of discomfort.
Every year, World Population Day is observed on July 11th, aiming to increase people's awareness of various population issues, such as the importance of urbanization, gender equality, poverty, health, and human rights. In 2025, under the theme "Empowering Youth to Build the Families They Want," the United Nations draws attention to the largest generation of young people in history, many of whom are coming of age in rapidly urbanizing contexts. Urban centers remain key to understanding these demographic patterns, as cities continue to attract populations seeking opportunity, stability, and access to essential services. Today, more than half of the global population resides in urban areas, a share projected to increase to 66% by 2050.
Designed by Zaha Hadid Architects in collaboration with the Guangdong Architectural Design & Research Institute, the Greater Bay Area Sports Centre in Nansha, China, is approaching completion. Construction began in August 2023, with the main structures of the stadium and arena topping out in February 2024. Roofing and curtain wall installations were finalized in February 2025, and the project has now entered its final phase of interior finishing and landscaping. The center is set for handover in June 2025, ahead of its role as a key venue for the China National Games in November.
