Matt Grossmann Marty Jordan The CSPP dataset is massive: over 2000 distinct variables of state politics and policy from 1990-2019 Data are collected and curated by the IPPSR at MSU team and merged into a common format with typical state identifiers (name, abbreviation, FIPS, etc.) 2/n

Matt Grossmann Marty Jordan IPPSR at MSU We then demonstrate the variation within state politics and the utility of a comprehensive dataset, which facilitates within-state research, cross-sectional research, and policy-specific analyses 3/n

Matt Grossmann Marty Jordan IPPSR at MSU Then, we demonstrate the need for state politics and policy researchers to pay close attention to research design. In applied setting using Devin Caughey and Chris Warshaw measures of citizen ideology we show model specification is extremely important for inferences

Matt Grossmann Marty Jordan IPPSR at MSU Devin Caughey Chris Warshaw All of the analyses and visualizations in this paper were done using the data and functions from the cspp R package by Caleb Lucas and myself. Available on CRAN here: cran.r-project.org/web/packages/c… and developmental version here: github.com/correlatesstat…

Matt Grossmann Marty Jordan IPPSR at MSU Devin Caughey Chris Warshaw Caleb Lucas This is dataset exists because of the incredible state politics community. Too many to mention, but we encourage anyone who has variables not in our dataset to submit to us (ippsr.msu.edu/public-policy/…) The dataset and R package make it easy to cite your work!

Updated @ippsr Correlates of State Policy dataset: ippsr.msu.edu/public-policy/… package, & app: cspp.ippsr.msu.edu/cspp/ Now: - 140 new variables, >2,000 state-year variables overall - 100% citation coverage - Improved codebook Share & use Our paper overview: cambridge.org/core/journals/…

MSU's IPPSR at MSU is hiring a new post-doc to manage the Correlates of State Policy project, as well as our expansion to Congressional policy & district data careers.msu.edu/en-us/job/5095… This is the post-doc successfully led by Josh McCrain & Caleb Lucas, who are going on to great things

Correlates of State Policy @ippsr v 2.6 update >3,000 state-year variables for analyzing determinants & effects of state public policy, including 70 new variables & improved citations, thx Caleb Lucas Use our r package & shiny app to segment or analyze ippsr.msu.edu/public-policy/…

Grad students! Check out APSA's brand new Strategies for Navigating Graduate School and Beyond: apsanet.org/gradschool. A vital resource. Please share widely! It has a political science focus, but so much of it is broadly relevant.
