Replication Data for: "Ninety-Nine Chambers and the Development of Comparative Legislative Studies, 2021–2025"

To trace the evolution of state legislative studies since SPPQ appeared, we examined articles focused on state legislatures published in it from 2001 through the middle of 2025 and in seven other journals where we would anticipate such work to appear: American Journal of Political Science (AJPS), American Political Science Review (APSR), American Politics Research (APR), Journal of Politics (JOP), Legislative Studies Quarterly (LSQ), Political Research Quarterly (PRQ), and Social Science Quarterly (SSQ).
