This paper introduces the CORESIDENCE Living Arrangements Data Base (CoLADB), a novel global database designed to address the significant gap in statistical information available for analysing the composition, distribution, and evolution of living arrangements over time. Utilizing comprehensive microdata from IPUMS International and the European Labour Force Survey (EU-LFS), CoLADB encompasses over 782 million individual records from 107 countries, spanning the period from 1970 to 2020. The database employs an innovative algorithm to reconstruct kinship relationships within households, providing a robust and scalable methodology for examining living arrangements. Additionally, CoLADB integrates kinship estimates from the Projections of Human Kinship project, offering deeper insights into the demographic landscapes of different regions. The development of CoLADB involved a collaborative effort with the Barcelona Supercomputing Centre, leveraging the computational power of MareNostrum V to process the extensive data. This resource is expected to be instrumental for researchers and policymakers, enabling evidence-based decision-making in areas such as housing, social services, and healthcare. The open-source R code used in this project is publicly available, promoting transparency and facilitating the development of new living arrangement typologies for diverse research goals.
