2. Exposure: Built-up Environment and Popula on In this sec on, the built-up area and the exposed popula on are discussed. Pre-damage building data from the open street maps was analyzed using GIS. Figure 3 shows the details of the urban areas in the Gaza Strip. The total number of buildings is 174,148, encompassing a total ground floor building area of around 49sq.km. The approximate building and popula on distribu on across the Gaza Strip are shown, respec vely, in the two maps below in Figure 3. These maps are based on data from Open Street Maps and the most recent LandScan popula on data of 1.97M, respec vely. While this popula on data is slightly lower than recent UNRWA es mates of 2.1M, the distribu on is likely s ll rela vely accurate. The color-coded heat map shows the hot spots of high popula on density within the strip. Notably, North Gaza and Gaza are amongst the most highly populated areas within the Strip, with their coinciding high building and popula on density clearly indicated. The broad distribu on of building coverage in the map to the le highlights the high level of less-populated dispersed peri-urban and rural se lements across the area.
