Yet it is lessunderstood how the process of generating good data isto be conceptualized, implemented, and sustained. Thispublication series—Delivering Data Impact in Asia andthe Pacific—showcases how the Data Division of the AsianDevelopment Bank (ADB) has helped countries to design,build, and maintain data capacity, especially in innovationsthat use novel data sources and techniques. either in geographical or economic units and/or improvemeasurements that cover extended time periods. Byintroducing new methods and data sources, these projectsequip DMCs with a speedy means to compile data.
