The Spanish Legislative Amendments Dataset

The Spanish Legislative Amendments Dataset provides comprehensive information on all amendments proposed to all executive bills introduced to the Spanish parliament from 1996 to 2023. At the bill level, the dataset provides information on the total number of proposed amendments to each bill (a total of 117.575), the group proposing the amendments; and the main characteristics of each bill to which amendments were proposed. These characteristics include the bill title, date of proposal, type of resulting law, the legislative committee that debated it, the bill topic, the number of parliamentary appearances organized along the bill’s debate, and the bill’s regional and european content. This is the first systematic dataset of legislative amendments in Spain, created using web scraping and text parsing techniques.
