The Coffee Line: Starbucks vs Dunkin' Dominance by U.S. State

The Coffee Line: Where Starbucks Meets Dunkin' Across America

This map visualizes the state-by-state balance of America’s two most recognizable coffee brands using a simple metric: the ratio of Dunkin' to Starbucks locations in each state. By shading states in vibrant Dunkin' orange/pink or deep Starbucks greens, it reveals where each brand holds the upper hand, and it draws a bold "Coffee Line" along the borders where dominance flips. A neutral gray highlights near-parity states, acknowledging the many places where loyalties are genuinely mixed.

While Starbucks maintains a sweeping national footprint—especially strong in the West and major metros—Dunkin' remains a cultural mainstay in the Northeast and Mid-Atlantic. The classification reflects intensity as well: subtle shades mark slim advantages, while the boldest hues indicate overwhelming dominance. Designed with a clean, modern aesthetic and a clear legend, the map is easy to read at a glance yet rich enough to spark debate about regional coffee culture, convenience, and brand identity. Note: figures should come from the same-year counts to ensure fair comparisons as store openings and closures change over time.

Why it matters: Coffee choices are habits, commutes, and communities. This map turns those routines into a compelling picture of regional identity—perfect for fueling the ongoing conversation about America’s East vs. West coffee culture.
