The concept of "all-age friendliness" is a nascent but profound topic that impacts the spatial quality and future development of cities. This study focuses on the main urban area of Wuhan as a research subject to address issues such as insufficient refinement and mismatches between age groups and spatial needs in current urban planning and construction. Leveraging big data from online public opinion, combined with techniques such as natural language processing and geospatial statistical analysis, we identify critical spatial issues related to different age groups and their distribution characteristics. We argue that spatial issues related to all age groups vary in content and emphasis. Old communities, schools and their surrounding neighborhoods, as well as commercial and office areas, are prone to issues specifically related to certain age groups. Urban transportation spaces and residential areas undergoing renewal are more likely to encounter issues pertaining to all age groups. Conversely, blue and green public spaces represent the least problematic spatial types. Based on these findings, we provide guidance for the nascent exploration of all-age friendly cities in China, focusing on two aspects: supporting the use of specific age groups and facilitating shared access for all ages. This research contributes to the ongoing efforts in enhancing the urban spatial quality and inclusivity for all age groups.
