In our new webinar series, presenters describe and discuss how their data sets address homelessness to foster discussion on future research. 

On June 3, 2021 Calgary Homeless Foundation, in partnership with the School of Public Policy at the University of Calgary, launched the first of our Data That Makes a Difference webinar series.  

 The subject of this first webinar focused on how short cross-sectional studies of the characteristics of homeless people garner a lot of attention, but several other varieties of data, now neglected, bear a lot more useful information. But neglecting these often neglected data has led to serious errors – and might do so again. 

 Our first webinar was attended by over 110 individuals, and our presenter discussed two varieties of data in particular – point in time counts and stocks and flows – demonstrating how they can illuminate both policy-making and understanding.  

 A full recording of the webinar is now available on the Data That Makes a Difference website 

 During the presentation, many attendees joined the lively question and answer discussion. Any questions that were not addressed during the live program, were answered by the keynote speaker, and can be accessed HERE 

 Our Presenter:  

Dan O’Flaherty is a professor of economics at Columbia University, and teaches urban economics and the economics of race. His books include Making Room: The Economics of Homelessness (1996), How to House the Homeless, with Ingrid Ellen (2010), The Economics of Race in the United States (2015), and Shadows of Doubt: Crime, Stereotypes, and the Pursuit of Justice, with Rajiv Sethi (2019). He has served as an aide to Kenneth A. Gibson, the first African American mayor of a major northeastern city. 

 Dan O’Flaherty has been studying homelessness for 30 years. He does so from the point of view of an economist, which means that he bases his ideas and recommendations on data, which is the focus for Data That Makes a Difference. 

 Mr. O’Flaherty has a ‘relaxed’ style of speaking and writing that makes difficult concepts and associated policy recommendations easily understood by non-experts. 

These characteristics mean he can blend the best of both worlds; as he is well-respected as an expert in the field of the economics of homelessness, but he is also able to place what he finds into a broader context using familiar, non-technical language.
