US Multi-Outlet News Headlines (2001–2024)

Dataset Summary

This dataset contains more than six million news headlines collected from five major U.S. news outlets between January 2001 and December 2024.

It was constructed to support longitudinal analysis of topic dynamics in U.S. news coverage across four presidential administrations (Bush, Obama, Trump, Biden). The dataset enables the study of structural shifts in topic attention, cross-outlet alignment, and synchronized responses to major political and social events.

This dataset is associated with the study:

“Long-Term Topic Dynamics in U.S. News Coverage” (2026).

Included outlets:

  • The New York Times (NYT)
  • The Los Angeles Times (LAT)
  • The Wall Street Journal (WSJ)
  • Fox News
  • MSNBC

Access and Usage

Due to copyright restrictions on publisher content, this dataset is distributed via gated access (request-based approval).

The dataset is provided for non-commercial academic research purposes only.

By requesting access, users agree:

  • Not to redistribute the headline text
  • To use the dataset solely for non-commercial academic research
  • To cite the associated publication when using the data

Dataset Structure

The repository contains:

  • Raw dataset (headline text and metadata as collected)
  • Preprocessed dataset (cleaned headline text and normalized dates)
  • LLM-category dataset (topic and category assignments used in the analysis)

Data Collection

Headlines were collected from official outlet sources via:

  • Archive APIs (e.g., The New York Times)
  • Public archive and sitemap pages

All parsing and preprocessing were conducted using standard HTML parsing and text-cleaning procedures.


Limitations

  • Archive availability differs across outlets.
  • Headlines are short textual summaries and may not fully reflect article-level framing.

Citation

We analyzed headlines in our paper. Will soon be released.
