Apartments are the most common type of housing in China, particularly in large cities. These apartments are typically small and may range from one-room units to larger three or four-room units. Detached homes, on the other hand, are less common and are usually found in suburban or rural areas.
It's important to note that these figures represent averages and can vary considerably based on several factors, such as the city or region, the economic status of the household, and the specific housing market at the time. Additionally, housing preferences and living arrangements in China can differ from those in other countries due to cultural, demographic, and economic considerations.
