The growth of the aging population continues to grow, it has become a global phenomenon because it occurs in almost all countries, both in developing and developed countries. This condition raises an important issue and policy because they tend to live longer, healthier, and active. Some of the elderly population, besides being healthy, are also equipped with education, skills, financial capital, and time to do activities so that they can make an economic contribution by continuing to work, one of them through entrepreneurship. This paper aims to provide empirical evidence for the determinant on entrepreneurial activity, in particular for elderly hours of work. Findings from the paper that economic factors (such as wages and non-labor income) as well as employment and other demographic variables affect older people's availability of entrepreneurship. However, those factors have no real influence in certain age groups, such as age 75 +. Our suggestion, the government needs to accommodate the elderly who still want to work. By creating conditions and conducive situations, they should continue to contribute such as increased economic productivity, tax revenues, and reducing the costs of retirement-related benefits.
