I am a data journalist at The Economist based in Washington, DC. I write mostly about American politics and elections, usually by engaging in a close study of political science, political polling and demographic data. I am responsible for many of the paper’s election forecasting models, including our 2020 US presidential election forecast. Here is a Reddit AMA where I discuss more of that work. I also write the paper’s weekly “Checks and Balance” newsletter on US politics.
I am writing a book for W. W. Norton on public opinion polling — its history, influence, successes, failures, and future — and why it is a crucial tool for a healthy democracy. Sign up for my newsletter to get updates as publication day approaches. My book (title TBD) is due out in 2022. You can read a short blog post about the project here.
I used to write a lot over at my old blog thecrosstab.com, but nowadays I do most of my blogging via my newsletter. You can read it and sign up at gelliottmorris.substack.com. One day I may transfer that old content here.
I also post a lot on Twitter: Follow @gelliottmorris
I am probably best known for my work on election forecasting models, which have enjoyed varied success since I began blogging about political statistics as a college student in 2015. These days, I am interested in how we can improve on the popular aggregation-based election forecasting methods by incorporating raw polling microdata and other non-poll data into our models. Such an approach can make crucial improvements in state-level estimates, decreasing the biases in our national probabilistic estimates and producing more reliable day-to-day forecasts. We can also use these methods to dive deeper into the attitudes of different demographic groups than the traditional methods, a key journalistic advantage.
I received my undergraduate degrees in government and history from The University of Texas at Austin in May 2018. As part of my coursework I also studied statistics and computer science. In 2017 I was a survey methodology intern at the Pew Research Center, and briefly produced statistical models for the election returns startup Decision Desk HQ between 2017 and 2018. I joined The Economist in February of 2018 while finishing my degree, and I’ve been here ever since.
Broadly speaking, I am motivated by an interest in better understanding the world using statistics, social science methods, data, and predictive models. I am also a firm believer in the power of public opinion polling to improve democratic outcomes.
