This dataset presents a collection of the official local governments’ Twitter activity in Buenos Aires Province in Argentina. The collection is entirely in Spanish and was built by crawling each local government's social media accounts and the reactions it received. The collection focuses on the content-based relations established between the local government authorities and the citizens, instead of on the follower/followee relationship. The dataset is useful for studying how government entities manifest themselves in social media and their different ways of transmitting information; and how citizens interact and express their commitment to the government entities. The collection includes the account activities during the COVID-19 pandemic. Data was collected using the Twitter API and will be periodically updated.
