We address the post-entry performance of new Portuguese firms by investigating the structural characteristics of the hazard and survival functions, using non-parametric survival analysis. In order to approach prevalence of some stylized facts and determinants of new firm survival, we produced a new entrepreneurship database, using the administrative data of Quadros de Pessoal, following the Eurostat/OECD´s internationally comparable business demography methodology. This allowed the computation of a comprehensive array of entrepreneurship indicators on employer enterprise and survival dynamics in Portugal, over a period of 18 years, disaggregated in dimensions such as sectors, regions and size classes.

JEL Classification: M13, M20.
