G. Elliott Morris | (Data) Journalist

About me


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.

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. No Margin For Error is due out in the fall of 2021. 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:


The work I am perhaps best known for is my election forecasts, 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 over the popular aggregation-based election forecasting methods by incorporating raw polling micro-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. Such methods also allow us 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 2018. As part of my coursework I also studied statistics and computer science. I used to intern at the Pew Research Center and briefly produced statistical models for the election returns startup Decision Desk HQ. I joined The Economist in February of 2018 while finishing my degree.

Broadly speaking, I am motivated by an interest to better understand the world using computational social science, public opinion surveys and predictive analytics. I also have a firmly-held belief in the power of political polling to improve democratic outcomes.
