ProPublica will launch a revamped news application featuring data organized in a way that makes it easier for reporters to write local stories about homes in their areas, comparing them to one another and ranking states against others.

ProPublica’s Charles Ornstein and Lena Groeger will walk conference call participants through the beta version of the app and answer any questions. Stories produced from this data will be embargoed until Monday, Dec. 17, when the new site goes live.
