Civil engineering doctorates awarded

Between 2002 and 2021, civil engineering doctorates awarded in the US and the cost of a 30-second Super Bowl ad both increased, correlating at 0.9652 across twenty data points. The implication is that the nation requires one additional PhD for every incremental million dollars spent on football advertising, a staffing ratio that sounds absurd until you realize that someone has to engineer the stadiums where these ads are watched. The civil engineer and the ad buyer have never met, but they are both beneficiaries of the same American conviction that infrastructure—whether physical or commercial—should always be getting bigger.

Civil engineering doctorates grew gradually from roughly 500 per year in 2002 to over 800 by 2021, driven by infrastructure investment, urbanization research, and climate adaptation engineering demand. Super Bowl ad costs rose from $2.2 million to over $6 million per 30-second spot, driven by the game's unique mass-audience position. Both are gradual upward trends across 20 years, one academic and one commercial, producing a strong correlation from shared directionality rather than shared causation.

Twenty years of two gradually rising series will produce a formidable correlation coefficient. The civil engineering PhD and the Super Bowl ad occupy entirely different economies, but the mathematics of gradual growth looks the same in both.
