In the last week, I have run into two potentially interesting news stories that cite studies. Yet, when I looked into what kind of studies these were, they were not what I expected.
First, the Chicago Tribune online headline: “Why are Chicagoans moving away during the pandemic? As study suggests outbound migration is spiking, we asked them.” The opening to the story:
Chicago’s population has been on the decline for years, with the metropolitan area suffering some of the greatest losses of any major U.S. city. But new research suggests that the pandemic might be exacerbating the exodus.
For the first time in four years, moving concierge app Updater has helped more people move out of Chicago than to it, the company said. The catch-all moving service estimates that it takes part in one-third of all U.S. moves, providing unique, real-time insight into pandemic-driven trends, said Jenna Weinerman, Updater’s vice president of marketing.
“All these macro conditions — job insecurity, remote work, people wanting to gain more space — are coming together to create these patterns,” Weinerman said.
The Chicago figures are based on approximately 39,000 moves within city limits from March 1 to Sept. 30. Compared to 2019, this year saw more moving activity in general, with an 8% jump in moves into the city — but a 19% increase in the number of people leaving.
The second article involved a study at Cafe Storage and the headline “Average Home Size in the US: New Homes Bigger than 10 Years Ago but Apartments Trail Behind” (also cited in the Chicago Tribune) From the story:
According to the latest available US Census data, the average size of single family homes built in the US was trending upwards from 2010 until 2017, when sizes hit a peak of 2,643 square feet. Since then, single family homes began decreasing in size, with homes built in 2019 averaging 2,611 square feet…
Location matters when it comes to average home size. Some urban hotspots follow the national trend, while others move in the opposite direction. Here’s how single family home and apartment sizes look in the country’s top 20 largest cities, based on Yardi Matrix, Property Shark and Point2Homes data.
As an academic, here is what I expect when I hear the word study:
- Peer-reviewed work published in an academic outlet.
- Rigorous methodology and trusted data sources.
These steps do not guarantee research free from error but it does impose standards and steps intended to reduce errors.
In both cases, this analysis does not meet those standards. Instead, they utilize more proprietary data and serve the companies or websites publicizing the findings. This does not necessarily mean the findings are untrue. It does, however, make it much more difficult for journalists or the public to know how the study was conducted, what the findings are, and what it all means.
Use of the term study is related to a larger phenomena: many organizations, businesses, and individuals have potentially interesting data to contribute to public discussions and policy making. For example, without official data about the number of people moving out of cities, we are left searching for other data sources. How reliable are they? What data is anecdotal and what can be trusted? Why don’t academics and journalists find better data?
If we use the word “study” to refer to any data analysis, we risk making it even harder for people to discern what is a trustworthy study and what is not. Call it an analysis, call it a set of findings. Make clear who conducted the research, how the analysis was conducted, and with what data. (These three steps would be good for any coverage of an academic study.) Help readers and interested parties put the findings in the context of other findings and ongoing conversations. Just do not suggest that this is a study in the same way that other analyses are studies.
