Abstract
The duration of unemployment, along with the unemployment rate, is one of the most important indicators of the labour market. It provides information on the scale of unemployment, along with its nature and socio-economic impacts. This article contributes through a unique database that contains information on the duration of unemployment, i.e., the time from the moment of registration to the moment of de-registration of unemployed people from the labour office. The database is extensive, contains information on a total of 299,668 people, and covers the years 2007–2024. These people were grouped into cohorts according to the year of de-registration. The unit of time analysed is the month. The numerical UDT database (Microsoft Excel) was created on the basis of information from the Poviat Labour Office in Szczecin, Poland. These data allow for the use of survival analysis methods and the inclusion of censored data in the study. Based on these data and the methodology of construction of life tables, unemployment duration tables were prepared, and a quartile analysis of the time of registration with the labour office was performed. The conclusions of such research may be a guide for policymakers to create employment policies and to promote activities supporting the unemployed.
