Data practitioners are often forced to make comparisons between disparate data sources. Data can vary in quality and completeness, and the trends they describe can differ in significant ways. When we try to compare these data, we're forced to challenge our assumptions and make tough decisions about steps to improve our confidence in our evaluations.The team at GovEx in charge of building the Standards of Living Tracker, a new tool for cities to monitor important characteristics about their populations, had to grapple with these challenges. In today’s episode, we’re joined by Sara Bertran de Lis, Adam Lee, and Angel Aliseda to discuss the hurdles faced during development of the tracker, and what’s next for the project as its launch approaches.To learn more about this tool and other projects at GovEx, visit govex.jhu.edu.
