GRID3 NGA - Comorbidities Risk Score at a 1km Squared Resolution

This score equally weights two components: 1) female adult obesity rate, and 2) elderly population. Female adult obesity rate is defined as the percentage of female adults aged 15 to 49 with a body mass index of over 30. This indicator is only available for females. Elderly population is defined as the number of people over the age of 50. Indicators are combined with z-scores at the 1km squared grid level. Source: Fraym 2020 The Fraym platform weaves together the latest satellite imagery and geostatistical datasets with professionally enumerated household surveys. This allows for the disaggregation and re-aggregation of large datasets to cover any geographically bounded area. Indicators are drawn and harmonized from a wide variety of household surveys and other data sources. These include the following sources: USAID: Demographic and health surveys United Nations: UN population division database World Bank: Enterprise surveys, living standards, global index surveys, and respective country statistics National Statistical Offices: National censuses and surveys covering population, businesses, health, housing, agriculture, and other areas International Monetary Fund: World economic outlook databases and respective country statistics National Air and Space Administration: Remote sensing satellite data, such as vegetation, temperature, and precipitation USGS: Landscan, Google Earth, GeoData Institute, OSM WorldPop: Population density by age groups
