This page points you to files for each of the individual countries. Each country has three files:

• A description of the methodology (a MS Word document)
• A detailed Excel spreadsheet that has all source data as well as the steps needed to create the gridded data. These files follow the convention of country_calc_person creating the file_date of last modification.
• An upload file that contains the major information (latitude, longitude, population, cell GDP in MER and PPP, and so forth). These files follow the convention of country_upload_person creating the file_date of last modification.

Note: The G-Econ project is a perpetual work in process. The project staff will be most grateful for suggestions or comments on the data, methodology, and other features. Any suggestions should be sent to william.nordhaus@yale.edu .
