At the Sloan Center on Aging & Work, one of our mandates is to collect information about issues that concern us and organize it online so that anyone who shares our interests鈥攃ertainly researchers, employers, employees, and policy makers鈥攃an find answers to their questions. Every week, we review reports and articles from reputable sources, evaluate the soundness of the research methods on which newly reported findings rest, and hold onto findings that are supported by the evidence presented. We post these 鈥渇acts鈥� to a听听available to the public. Each fact in the database is accompanied by a full citation, a brief description of the study methods and data used, and a link to the original source.

The vetting process is solid and straightforward. So why is it that some facts seem to contradict others? And when we鈥檙e confronted with facts that don鈥檛 jibe, how can we reconcile them to settle a perplexing question?

Consider this question, for example:
We鈥檝e been hearing a lot about older adults who have lost their jobs during the economic downturn and then, unable to find a new job, have become self-employed or launched their own businesses. These stories create a perception that self-employment and entrepreneurship among older adults are on the rise because of the recession. Is this true? Does the evidence support the perception?

Now consider the following two facts on self-employment recently posted to our database.

In other words, the rate of self employment among older adults (age 55 and up)听stayed about the same听from 2007 to 2012, although the total number of people in this age group who are self-employed increased.

So this study finds that entrepreneurial activity among older adults (between the ages of 55 and 64)听decreased听from 2010 to 2011.

Comparing analyses from different sources can be tricky, because investigators don鈥檛 define the concepts they are examining in the same way. Here, for example, self-employment and entrepreneurship mean different things. The U.S. Bureau of Labor Statistics (BLS) counts workers as 鈥渟elf-employed鈥� if they鈥檙e employed in their own business, profession, trade, or farm but have not incorporated these enterprises. (When self-employed workers incorporate, the BLS considers them to be employees of the corporations and classifies them as wage and salary workers.) The Kauffman Foundation defines entrepreneurial activity as the creation of new businesses鈥攏ot their maintenance in the years following. Thus, the figures Kauffman cites (drawn from monthly surveys conducted jointly by the U.S. Census Bureau and the BLS) are the percentage of the adult, non-business-owner population that starts a new business.

Given the two facts shown above, we can say that while the rate of unincorporated self-employment among older adults has stayed about the same over the past three years, older adults started new businesses at a somewhat slower rate during the past year. With respect to our question, 鈥淚s entrepreneurship among older adults on the rise because of the recession?鈥� the evidence presented here combines to suggest that the answer is 鈥渘o.鈥�

But two facts from two different sources are not really sufficient to answer a question. One must look instead for clusters of facts that trend one way or another. To help you do just that, the Sloan Center鈥檚 database holds 95 facts (as of today) covering a twelve-year period of research on the topic of 鈥�.鈥� And there are 48 other topics, each with its own rich and growing repository, ready to be mined.
