 abstract = {Data from the public use sample of the 1900 census are used to study the proper labor force classification of older male Americans experiencing 6 months or more of unemployment in the previous year ("long-term unemployed"). In terms of their personal characteristics, the long-term unemployed were similar in many respects to persons with a gainful occupation. Because the probability of re-employment, conditional on unemployment, appears to have declined with age, the probability of experiencing long-term unemployment rose as persons aged. Census data are consistent with the view that the older an individual was upon entering the status of long-term unemployment, the greater the likelihood the person would leave the labor force in a short period of time. I conclude, however, that this is insufficient reason to exclude the long-term unemployed from the count of gainful workers in 1900, as has recently been advocated.},
