Article Synopsis
  • Secondary data sources, like administrative records and Google Maps, are often used to understand access to food, but their reliability in non-WEIRD countries is unclear.
  • This study examined the accuracy of these data sources in Montevideo, Uruguay, finding that out of 1200 food outlets identified through field validation, 463 were missing from the databases and 297 listed outlets were either closed or nonexistent.
  • Results showed moderate overall validity of the data, with a notable variation based on the socio-economic status of the areas, indicating caution is needed when using these data sources, especially in lower-income regions.*
