POPGRID facilitates engagement among data holders, data users, and donors with the purpose of advancing research projects that require population data. POPGRID's website provides links to various GIS data sources, intending "to improve data access, timeliness, consistency, and utility; support data use and interpretation; identify and address pressing user needs; reduce duplication and user confusion; and encourage innovation and cross-disciplinary use." This effort to improve access to new population data sources aim to fill the gap that traditional census data creates due to large interval in data collection, lack of data from vulnerable communities, and others.
