Done by Javier Eslava-Schmalbach, Professor at Universidad Nacional de Colombia. Coordinates were obtained from: http://download.maxmind.com/download/worldcities/worldcitiespop.txt.gzg. For each Country a mean of Lattude and Longitud cities values was estimated; Maternal mortality Rates were obtained for 2015, from https://data.unicef.org; Values of Groos Deep Product and Income Country Group were obtained from http://api.worldbank.org and http://databank.worldbank.org. Estimation of attibutable fraction could be practiced at https://jheslavas.shinyapps.io/attributablefractio/. Attributable Fraction was estimated using this formula: ((Local Mortality-Lowest Mortality)/Local Mortality)
