This repository allows the reproduction of the analyses carried out in the article "Transition to adulthood and the intergenerational transmission of disadvantages among young adults in Spain". The repository contains two folders: one with the code and the other with the output data. The output data includes the processed data sets. These data sets can be useful for other researchers willing to analyse this same data for the same or other purposes. Original raw data is not provided here as we are not allowed to re-publish it. However, original data is publicly available here:

• 2018 Spanish Fertility Survey (Encuesta de Fecundidad): https://www.ine.es/dyngs/INEbase/es/operacion.htm?c=Estadistica_C&cid=1254736177006&menu=resultados&idp=1254735573002#_tabs-1254736195425
• 1996-2021 Birth Records (Registros de Nacimiento): https://www.ine.es/dyngs/INEbase/es/operacion.htm?c=Estadistica_C&cid=1254736177007&menu=resultados&idp=1254735573002#_tabs-1254736195443

Users can run the code following the especified order of the scripts. The data sets generated by the scripts follow the same numeration of the code. However, given the considerable amount of time and computational requirements for running the scripts, we recommend using the output data sets directly instead of rerunning the code that generates them.
