Social sciences rely on counterfactual analysis using surveys and administrative data, generally depending on strong assumptions or the existence of suitable control groups, to evaluate policy interventions and estimate causal effects. We propose a novel approach that leverages the Transformer architecture to simulate counterfactual life trajectories from large-scale administrative records. Our contributions are: the design of a novel encoding method that transforms longitudinal administrative data to sequences and the proposal of a generative model tailored to life sequences with overlapping events across life domains. We test our method using data from the Istituto Nazionale di Previdenza Sociale (INPS), showing that it enables the realistic and coherent generation of life trajectories. This framework offers a scalable alternative to classical counterfactual identification strategy, such as difference-in-differences and synthetic controls, particularly in contexts where these methods are infeasible or their assumptions unverifiable. We validate the model's utility by comparing generated life trajectories against established findings from causal studies, demonstrating its potential to enrich labour market research and policy evaluation through individual-level simulations.
