Elderly Population Ratio in Lisbon

Overview This feature service provides spatial data representing the ratio of elderly people—defined as individuals aged 65 and over—across grid areas in the Lisbon region. The data is compiled and managed by the Institute of Geography and Spatial Planning of the University of Lisbon (IGOT). Feature Layer Elderly people ratio: This layer illustrates the percentage representation of elderly individuals within each grid cell. It includes geographic identifiers such as grid IDs and polygon shape measurements that define the area's extent and form. The data assists in analyzing the demographic distribution of senior populations spatially. Geographic Coverage The data covers urban and surrounding areas within the Lisbon region, offering granular demographic insights at the grid level. Use Cases Urban and social planners can utilize this information to address age-related community service needs and infrastructure planning. Public health and social agencies may use the data to target resource allocation for elderly care and support programs.
