Abstract

This paper presents a longitudinal open dataset of Spanish public procurement extracted from the Official State Gazette (BOE) covering the period 2014-2024. The dataset integrates structured information on contracts, contracting authorities, suppliers, amounts, and procedures, enabling large-scale quantitative analysis of public procurement dynamics in Spain. We describe the data extraction and normalization pipeline, provide descriptive statistical analyses of temporal and sectoral trends, and discuss potential applications in transparency research, public policy evaluation, and computational social science. The dataset is released to facilitate reproducible research on public procurement and government contracting.
