a 1-km-resolution density maps of total POI number of six critical infrastructures. Maps of total POI number per thousand residents across country (b) and state (c) levels. d Composition of different POI types per thousand residents across different continent (Africa, Asia, Australia/Oceania, Europe, North America, and South America), urbanization (Global North and Global South), and income (high, upper middle, lower middle, and low incomes) contexts. Income information is from the World Bank database according to 2022 gross national income (GNI) per capita: low income, 1135 USD or less; lower middle income, 1136–4465 USD; upper middle income, 4466–13,845 USD; and high income, 13,846 USD or more. Population density is extracted from the 100-m resolution WorldPop dataset. The boundaries vectors for country, state, continent, and Global North and Global South are from the Global Administrative Unit Layers (GAUL) dataset provided by the Food and Agriculture Organization (FAO) of the United Stations (https://data.apps.fao.org).
